The answer is C.

It is the site of gas exchange in the lungs.

Gas exchange occurs only in alveoli. Alveoli are made of thin-walled parenchymal cells, typically one-cell thick, that look like tiny bubbles within the sacs. Alveoli are in direct contact with capillaries (one-cell thick) of the circulatory system.

Why does climate change affect so many things?

Answers

Answer:

These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.

Explanation:

According to me there are several causes of climate change, but all the problems are based upon a major problem which is over population. Either it is deforestation, any kind of pollution, global warming or whatever it is, all these problems are inter-linked and all are due to increasing population.

define the term (1)semi-permeable membrane (2) osmosis tell the answer i will mark u as brainlist​

Answers

Answer:

a)the outermost part of an animal cell that selectively allows things to pass through and come out.

b) the passing of water molecules from higher conc. to lower conc.

Answer:

(a) Semi-permeable membrane:

A semipermeable membrane is a membrane that only allows the movement of solvent molecules but restricts the movement of solute particles across the membrane.

(b) Osmosis:

The process of movement of water molecules from a region of higher concentration to a region of lower concentration through a semipermeable membrane is called osmosis.

When two nearby concentrations are different, materials will tend to spread out to equalize the concentration. For example, if you put a drop of food colouring in some water it will gradually spread through the whole water.

What is a disadvantage of using a space-filling model to show a chemical compound?

Answers

Answer:

Explanation:

The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond.

The diagram below shows a light ray striking Medium A and Medium B at the same angle. (4 points)

A rectangle labeled Medium A is drawn on the left. A ray of light travels through air and strikes the surface of medium A making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium A and makes an angle of about 15 degrees with the vertical. A rectangle labeled Medium B is drawn on the right. A ray of light travels through air and strikes the surface of medium B making an angle of 50 degrees with the vertical. The light ray bends towards the vertical as it travels through Medium B and makes an angle of about 25 degrees with the vertical.

Which statement is correct?
The speed of the light ray is the same in air and Medium A.

The speed of the light ray is the same in air and Medium B.

Medium A and Medium B have different densities because light refracts at different angles.

Medium A and Medium B have the same density because the light ray strikes both at the same angle.

Why people get cholera in our community​

Answers

Answer:

Search Results

Featured snippet from the web

A person can get cholera by drinking water or eating food contaminated with cholera bacteria. In an epidemic, the source of the contamination is usually the feces of an infected person that contaminates water or food. The disease can spread rapidly in areas with inadequate treatment of sewage and drinking water.

Explanation:

The mode of transmission of Cholera is through fecal contamination of food or water. Transmission is therefore closely associated to poor environmental management due water and sanitation issues

Write down the functions of
1.microtubules
2.tripletsof microtubules

Answers

Answer:

Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility

Centrioles are cylindrical structures that are made up of protein tubes called microtubules. Specifically, nine groups of three microtubules, known as triplet microtubules, are linked together to make the walls of the cylinder.

Hope it helps :)

Answer:

Microtubules have several functions. For example, they provide the rigid, organized components of the cytoskeleton that give shape to many cells, and they are major components of cilia and flagella (cellular locomotory projections). They participate in the formation of the spindle during cell division (mitosis).

triplet microtubules are linked together to make the walls of the cylinder.

Answers

Answer:

have variation that can be passed from one generation to the nextsurvive longer than another organismhave adaptations to their environment. have differential reproductive success.

Explanation:

Naturla selection is the survival and reproduction of individuals due to different phenotypes. The naturla selection represents a mechanism of evolution and changes in traits of species.

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Natural Selection is a mechanism of evolution that occurs when there is a heritable variation for a trait and individuals with one version of the trait have greater reproductive success than do individuals with a different version of the trait.

In order for natural selection to occur, three conditions must be met:

There must be variation for the particular trait within a population.The variation must be inheritableIndividuals with one version of the trait must produce more offspring than those with a different version of the trait.

Thus,

In order for natural selection to occur, organisms must :

have a variation that can be passed from one generation to the next.have differential reproductive success.

Fossils: In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms.

 

Explanation:

The evolution theory is supported by multiple sorts of evidence: homologous structures show common ancestry, whereas similar selective pressure will manufacture similar variations. analogous structures (beneficial features).

In the oldest rocks area unit fossils of the best organisms and within the newest rocks area unit fossils of additional advanced organisms. This supports Darwin's organic process theory, whereby straightforward life forms {progressively|increasingly|more and additional} evolved into more advanced. Proof of adolescence forms comes from fossils.

A.All organisms have a common biochemical evolutionary origin.

B.Organisms can live without genetic code.

C.Four nucleotides.

D.Four nucleosides.

Answers

Answer:

A. All organisms have a common biochemical evolutionary origin.

Explanation:

Genetic code is the biological mechanism by which the DNA in our body is used to synthesize protein needed for growth and development. The genetic code comprises of all the possible 64 codons i.e. a group of three nucleotides that encode an amino acid.

One of the characteristics of the genetic code is that it is UNIVERSAL. This means that all known living organisms make use of the same genetic code and hence, this portrays that all living organisms share a common biochemical evolutionary origin.
