Sindrei [870]

Answer:

The correct answer is option E.

Explanation:

The effect on the growth of the full sunlight and green light or the increased carbon dioxide and normal air. There are several effects that can affect the growth of the plant can be affected. Provided options are directly or indirectly affects the variables that are unknown but can affect the growth of plants.

Increased in carbon dioxide does not leads to the decrease of other essential gasses in substantial amount, common uniform strain of seedlings are also cause effects the experiment of plant growth in specific manner. Light is also one of influential and limitation factor that affects the growth of the plant.

Thus, the correct answer is is option E.

A protein domain is another phrase describing what type of structure of a protein?.
dlinn [17]

Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds

independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.

One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.

In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.

The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.

Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.

Why must the cell move things in and out of it?
Varvara68 [4.7K]

Answer:

Moving things in and out of the cell is an important role of the plasma membrane. It controls everything that enters and leaves the cell. There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy.

Systemic fungal infections (e.g. Candida and Cryptococcus) and tuberculosis (Mycobacterium) are on the rise. One of the reasons
miss Akunina [59]

Answer:

a) the molecules can be found in the picture below

b) (i) isocitrate lyase ( isocitrate to glyoxylate)

   (ii) malate synthase (glyoxylate to malate)

c)  Glyoxylate cycle do no exist in animals

Explanation:

b) in the glyoxylate cycle isocitrate lyase helps in conversion of  isocitrate to glyoxylate. Also, helps in conversion of glyoxylate to malate by using malate synthase.

c)   Glyoxylate cycle do no exist in animals, it only exist in plants and bacteria. This is because they can produce glucose from acetyl-CoA in required amounts.They have the ability to change acetyl-CoA from fat into glucose. But in animals, this mechanism is not possible.

Explain how increased CO2 in the atmosphere results in greater acidification of oceans and describe the effect on marine organis
marishachu [46]

Answer:

When carbondioxide gas is emitted from vehicles and industries and goes upward in the atmosphere. The carbondioxide gas combines with the rain water forming an acid called carbonic acid and make the rain acidic.

When rainfall occurs this acid comes to the ground and ocean and adversely affected the living organisms due to acidic nature. The marine animal's body comprise of shell and skeleton. This skeleton and shell are made from calcium, when acidification of ocean water occurs, the calcium dissolved and the body of animals are destroyed.
