How can the energy stored in the photosynthetic organism be used?

Answers

Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy stored in the bonds to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as movement.

Explanation:

The sac-like structure of the alveoli increases their surface area. In addition, the alveoli are made of thin-walled parenchymal cells. These features allow gases to easily diffuse across the cells. so the

Alveoli has thin walls which are surrounded by blood vessels, and they have maximized are for gas exchange. Thus, option A, B, and D are correct.

What are Alveoli?

These are basic respiratory units, which are balloon like structure present in the lungs, where exchange of gases takes place. A pair of human lungs can contain approximately 480 million alveoli, which produces about, 50 to 75 square meters surface are.

Alveoli are made of thin walls, and they are covered by a rich blood supply through capillaries, this supplies a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.

Therefore, the larger surface area, presence of thin wall, which is only one cell thick,  and rich blood supply due to presence of blood vessels enable them to exchange gases efficiently.

Answers

Answer:

Limiting factors fall into two broad categories: density-dependent factors and density-independent factors. These names mean just what they say: Density-independent factors have an impact on the population, whether the population is large or small, growing or shrinking.

the density-dependent factor example is:

Density-dependent factor, also called regulating factor, in ecology, any force that affects the size of a population of living things in response to the density of the population (the number of individuals per unit area).

the independent factors example is:

Pollution. Like other density independent factors, pollution is a good example of a density independence.

Explanation:

Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource.

A protein may fold incorrectly if_________ brings the wrong amino acid to the ribosome to assemble the protein.

Answers

YOUR ANSWER IS tRNA because the mRNA sends out a message to the tRNA and the tRNA brings back the appropriate amino acid but if the tRNA where to bring back the wrong the protein could fold incorrectly.

If tRNA does not bring back the appropriate amino acids, the protein may fold incorrectly. so, the blank is tRNA.

What is tRNA?

The type of RNA that helps in the synthesis of proteins from mRNA, called as tRNA. tRNA acts as an adapter molecule during the translation process, and as an adapter, it connects amino acids to nucleic acids. It carries the amino acids that are added to the peptide chain and decodes the same codons in the mRNA molecule.  

The structure of tRNA can be separated into primary, secondary and tertiary structures. The structure tRNA has four arms (the acceptor, D, anti-codon and -arms), three loops (D, anti-codon and -loop) and a variable region.

It binds amino acids to specific codons present in the mRNA, by acting as an adapter. Therefore, If tRNA bring wrong amino acid to ribosome for assembly of protein, protein may fold incorrectly.

The arrows in the picture below show several ways heat is transferred from the Sun as it strikes sand on the surface of a beach. Which arrow shows convection?

A.
1

B.
2

C.
3

D.
4

Answers

4 shows convention because the heat is coming from out of the ground into the atmosphere

Arrow 4 show convection. Thus option 4 is correct.

What is convection ?

The process in which transfer of heat occurs by movement of a heated fluid either air or water called as convection.

Initially the heat transfer through conduction, however a bulk heat transfer takes place due to the motion of the fluid.

The mechanism of convection involved,  fluid is heated from below, leads to thermal expansion.

So that the lower layers,  which are hotter now, become less dense.

So the less denser layer replaced by colder layer due to buoyancy nd colder layer is more dense.

This process continuously occur  and heat transfer occur through convection

It  occurs in both liquid and gases, may be natural or forced, bulk transfer occur.

Thus option 4 is correct.
