Flagella are found in both prokaryotic cells but are structurally different. For cells anchored in a tissue like the epithelial cells lining our air passages this moves liquid over the surface of the cell eg driving particle-laden mucus toward the throat.
Many of these organisms are found in aqueous environments where they are propelled along by the beating of cilia or the whip-like action of flagella.
Cilia and flagella function. Functions of Cilia Cilia are used for locomotion in isolated cells such as some protozoa eg Paramecium. For single cells such as sperm this enables them to swim. They are minute especially differentiated appendices of the cell.
The cilia and flagella are full of the cytosol to their tips and use the ATP in this cytosol to generate force along their entire length. The main difference between cilia and flagella is in their function not structure. They are locomotory in structure.
Primary cilia are immotile and are not undulipodia. Functions of Cilia and Flagella Flagellum acts as the locomotory organs in many algae and other protists. Cilia and flagella are cell organelles that are structurally similar but are differentiated based on their function andor length.
On the other hand flagella are longer and there are fewer flagella per cell usually one to eight. At the base of the cilium where it attaches to the cell body is the microtubule organizing center the basal body. Cilia arise from the basal granules.
They are the means by which many microscopic unicellular and multicellular organisms move from place to place. Cilia occur in the columnar epithelial cells of the respiratory and uterine tube. Cilia are smaller structures which work like oars.
On the other hand flagella are comparatively longer responsible for cell movement. In multicellular organisms cilia function to move a cell or group of cells or to help transport fluid or materials past them. Propelling cells - Using cilia or flagella cells are able to move freely in their environment especially in aquatic or moist environments.
Cilia play such important roles in the human body that defects in their function can cause diseases. Cilia move together in a coordinated way while flagella move independently. Flagella move with undulatory motion in which successive bending waves progress along the length of the organelle whereas cilia move with flexural motion consisting of a planar effective stroke with the organelle extended perpendicular to the cell body followed by a nonplanar curving recovery stroke with the organelle pulled parallel to the cell body.
Both cilia and flagella are structurally identical organelles. Cilia and flagella move liquid past the surface of the cell. Differences of cilia vs.
Microvilli mainly occur in the columnar epithelial cells of the small intestine and kidney tubules. Eukaryotic flagella are classed along with eukaryotic motile cilia as undulipodia to emphasize the role their distinctive wavy appendage plays in cellular function or motility.

In multicellular organisms these serve as gametes or help move cells or cell contents. Difference Between Cilia and Microvilli Occur in. Cilia are short and there are usually many hundreds cilia per cell.
Sensory functions - Some cilia and flagella allow cells to sense changes in their surroundings which in turn allows the cells to respond appropriately. Cilia and Flagella are complex filamentous cytoplasmic structures protruding through a cell wall. Depending on the type of cells cilia and flagella have the following functions.
Microvilli do not arise from the basal granules. Flagella include location movement and length. Flagella are found on sperm cells.
A large number of cilia tend to be located over a wide area of the cell surface while flagella are either solitary or few in number. Brought to you by Sciencing. This activity of cilia causes the movement of either the cell or the surrounding fluid.
Single-celled microorganisms use cilia and flagella for locomotion. Exceptions include Drosophila sperm and Plasmodium falciparum flagella formation in which cilia assemble in the cytoplasm. Flagellum circulates food in the gastro-vascular cavity in coelenterates or spongocoel choanocytes in sponges.
Cilia are short hair-like structures found in high density on the surface of mammalian cells. Cilia exhibit a back and forth beating while flagella exhibit propeller-like motion. Flagella singular flagellum are long hair-like structures that extend from the plasma membrane and are used to move an entire cell.
They both are the appendages of the plasma membrane of the cell and arise from the basal body.

Acid Rain Students Site Ph Scale
The acid pH readings would be very different if we had the same pH reading in untreated tap water containing a large quantity of buffering chemicalsin that case we would be describing a much stronger acid solution which would require a great deal more base to.
Ph of pure water. Thus the ions H and OH- are always paired as the concentration of one increases the other will decrease. Afterwards the water is infused with. Alkaline water has a pH of 8 or above.
For example the hydronium molarity of pure water is 80 C is 49 10 7 M which corresponds to pH and pOH values of. Regardless of pH the sum of the ions will always equal 10¹⁴ M ². This type of reaction in which a substance ionizes when one molecule of the substance reacts with another molecule of the same substance is referred to as autoionization.
The hydrogen ion concentration equals the hydroxide ion concentration and both equal 1 X 10 - 7 M. PH log H 3 O log 49 10 7 631 pOH log OH log 49 10 7 631. While seawater has a pH of around 80 and baking soda has a pH of approximately 80.
Meanwhile a very strong base is household lye which has a pH of approximately 135. Pure water has a pH of 7 and is considered neutral because it has neither acidic nor basic. A stronger base is milk of magnesia which has a pH of around 106.
A solution with a pH of 7 at this temperature is slightly alkaline because its pH is a bit higher than the neutral value of 614. At 100C the pH of pure water is 614. Water with a pH less than 65 is considered acidic.
Although the pH of pure water is 7 drinking water and natural water exhibits a pH range because it contains dissolved minerals and gases. Because pure water is neither an acid or a base it has a pH of 7. A neutral solution is one that is neither acidic nor basic.
The pH of pure water is 7 the negative logarithm of 1 X 10-7. A neutral solution is one that is neither acidic nor basic. Unluckily not every kind of water available is pure water and the chance of getting the actual neutral level is in fact rare.
The most alkaline substances such as lye have a pH of 14. In pure water a very small fraction of water molecules donate protons to other water molecules to form hydronium ions and hydroxide ions. The neutral pH of 7 located in the middle of the pH scale is considered to be pure water.
Once pure water mixes with saliva the pH values will change instantly. Nestle Pure Life water is bottled from a municipal source and goes through a multi-step process of filtration that involves reverse osmosis andor distillation. This means that at 50 C pure water has a pH of 661 while at 0 C it will have a value of 747 pH.
At 25 C it is 700 and at 100 C it is 614. The fluctuation is caused by varying factors affecting the alkalinity and acidity of water. A solution with a pH of 7 at this temperature is slightly alkaline because its pH is a bit higher than the neutral value of 614.
For instance at 0 C the pH of pure water is about 747. But why do pH levels change. That is the neutral point on the pH scale at this higher temperature.
The pH of water is defined as the negative logarithm of the hydrogen ion activity which is often assimilated to the hydrogen ion concentration Eq Table 1. This definition was adopted because ion-selective electrodes which are used to measure pH respond to activity. All of these substances are weak bases.
Purified water is water that has been mechanically filtered or processed to remove impurities and make it suitable for use. Indeed the dissociation of water and the ionic product for water Eqs. However pure water does not really exist in nature due to the ubiquitous presence of minerals and other natural and man-made contaminants.
At 100C the pH of pure water is 614 which is neutral on the pH scale at this higher temperature. While the pH of pure water is approximated to be 70 at 25 C the theoretical value is 6998. Distilled water has been the most common form of purified water but in recent years water is more frequently purified by other processes including capacitive deionization reverse osmosis carbon filtering microfiltration ultrafiltration ultraviolet oxidation or.
At a neutral pH of 7 pure water the concentration of both H ions and OH- ions is 10⁷ M. The pH balance of LIFEWTR ranges between 64 to 74 which makes it slightly less acidic than standard tap water. The amount of temperature change involved and the critical nature of the measurement dictate if this effect must be compensated for or not.

Mass is always constant for a body and there are several formulas to calculate mass. This video aims to tease out the difference between mass and weight by asking. F force N lb f.
Mass is the scalar quantity and weight is a vector quantity. Mass is an intrinsic property of the body and remains the same wherever the body might be. For example you may weigh 100 pounds on Earth but in outer space you would be weightless.
Mass is a scalar quantity whereas weight is a vector quantity. Weight is denoted by W. For instance an object weighs differently on the Earth and Mars but its mass remains the same.
Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity. Weight is the measure of the force of gravity on an objects mass while mass is the measure of how much matter there is in an object. The fundamental relation between mass and weight is defined by Newtons Second LawNewtons Second Law can be expressed as.
If gravity is constant weight and mass are the same. Mass is denoted using m or M. In this short video Nigel and Martin discuss the differen.
If an object mass is heavy it has more inertia and larger the weight it has more inertia too. The difference between mass and weight is that mass is the measurement of how much matter is contained within an object whereas weight is a measurement of how much gravity is pulling down on an object. The weight of a body changes if the gravitational field strength changes however its mass remains invariant.
However you will always have the same mass on Earth as you. The difference between mass and weight is that mass is the amount of matter in a material while weight is a measure of how the force of gravity acts upon that mass. W mg W m 1 W m.
Mass is the measure of the amount of matter in a body. Mass is a measure of the amount of material in an object being directly. So there is a similarity between mass and weight in the measurement issue.
The mass never changes with place but weight does. Mass is simply the measure of the amount of matter in a body. Do you know the difference between Mass and Weight.
In common usage the mass of an object is often referred to as its weight though these are in fact different concepts and quantitiesIn scientific contexts mass is the amount of matter in an object though matter may be difficult to define whereas weight is the force exerted on an object by gravityIn other words an object with a mass of 10 kilogram weighs approximately 981 newtons. The weight of an object is its mass times the acceleration due to gravity. Weight is different from mass.
So Mass and weight are similar on the basis of inertia. Watch this video to understand the concepts of mass and weight.
The octet rule denotes the tendency that the elements in the S and P blocks of the periodic system preferably will have 8 electrons in the outer shell. When atoms have fewer than eight electrons they tend to react and form more stable compounds.
Furthermore all electrons lost by one kind of atom must be gained by the other.
What is the octet rule. Assistant Professor Salt Lake Community College Salt Lake City Utah View all posts by Chris. Lewis through a theory based on a cubical atoms. In this way the element will look like a noble gas that is not reactive.
The octet rule can then be applied. The octet rule is a chemical rule of thumb that reflects the theory that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell giving it the same electronic configuration as a noble gasThe rule is especially applicable to carbon nitrogen oxygen and the halogens but also to metals such as sodium or magnesium. It was formulated by a man named Gilbert N.
Each atom will share gain or lose electrons to fill these outer electron shells with exactly eight electrons. Each atom must lose or gain electrons in order to achieve an octet. What does octet rule mean is that atoms of the main elements develop a tendency in participating in chemical bonding that the resulting molecule of every atom contains eight electrons in the valence shells.
Significance of Octet Rule Octet rule which can explain the chemical bonding in different compounds. The octet rule is a general rule of thumb that applies to most atomsIt states that every atom might want to have eight valence electrons in its outermost electron shell. What is the Octet Rule Octet rule is called the chemical rule of thumb.
Updated August 04 2019 The octet rule is a bonding theory used to predict the molecular structure of covalently bonded molecules. According to the Bohr model an atom consists of a nucleus of protons and neutrons orbited by a number of electrons. The octet rule in chemistry is a chemical rule that explains the rules of atoms electrons and their forms.
The element attaining octet configuration has completely filled outermost s and p orbitals. Octet rule Back to Glossary Index. The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell.
When atoms have fewer than eight electrons they tend to react and form more stable compounds. The valence shell can hold up to 8 electrons. Eight electrons in the outer shell allows atoms to have a configuration that is similar to the closest noble gas.
Are expressed by his celebrated octet rule which states that electron transfer or electron sharing proceeds until an atom has acquired an octet of electrons ie the eight electrons characteristic of the valence shell of a noble gas atom. It is based on the observation that the atoms of the main group elements have a tendency to participate in chemical bonding in such a way that each atom of the resulting molecule has eight electrons in the valence shell. The octet rule is an informal measure of how favorable a chemical bond is between atoms.
A rule that says the outer valence shell of electrons is complete when it contains 8 electrons. The octet rule is a general rule of thumb that atoms will form bonds either ionic or covalent in order to fill the octet of their valence shell. When complete transfer occurs the bonding is ionic.
In 1919 Irving Langmuir refined these concepts further and renamed them the cubical octet atom and octet theory. Lewis referred to this insight as Abeggs rule and used it to help formulate his cubical atom model and the rule of eight which began to distinguish between valence and valence electrons. It defines the propensity of elements belonging to the main groups in the periodic table to react with each other to form compounds and become stable.
Following the octet rule results in completely filled s- and p- orbitals in an atoms outermost energy level. 3 Minerals Back to Glossary Index. Accordingly atoms can combine either by transferring valence electrons from one atom to another gaining or losing or by sharing valence electrons so as to have one octet in their valence shells.
According to the rule atoms seek to have eight electrons in their outeror valenceelectron shells. Why Elements Follow the Octet Rule Atoms follow the octet rule because they always seek the most stable electron configuration. The octet rule can be used both in connection with ions and covalent bonds.
A valence shell is the outer shell of an atom. The octet rule is one of the chemical rules of thumb stating that atoms prefer to combine in a manner such that each atom has 8 electrons in their valence shells. The octet rule dictates that atoms are most stable when their valence shells are filled with eight electrons.
What is the Octet Rule. The octet rule states that atoms gain stability when its outer valence shells comprise eight electrons. This law is known as the Octet rule.
An exception to the octet rule occurs in the case of the three ions having the He 1s 2 structure that is H Li and Be 2. Everything within our planet is made up of atoms and it is interesting to understand how they work.
