A particular hormone travels by many types of cells in the body. Which mechanism ensures that it acts only on the target cells?

1 answer:

4 0

The mechanism that ensures that it acts only on target cells is that each target cell has a particular receptor for that particular hormone. This makes it impossible for other cells to work with the hormone. This is the reason that different hormones are accepted by different cells very easily. I hope this answer helps you.

<h3>General characteristics of plants</h3>

Plants are classified as autotrophic organisms, since the large one is capable of photosynthesis. With the exception of plants, some achlor species being observed, therefore, not achlorizing plants.

<h3>Chloroplast</h3>

Chloroplast, a structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.

<h3>It happened in real life</h3>

The newly discovered plant — named Gastrodia kuroshimensis — occurs in the dark understory of forests, where little light penetrates. So instead of using sunlight or photosynthesis to generate nutrients, the plant parasitizes the fungi in the forest soil for its daily dose of nutrition.

With this information we can say that the correct alternative is B. where it states that there are no chloroplasts in the plant cells.

B. There are no chloroplasts in the plant's cells.

These plants that do not photosynthesize do not have the green pigment, what gives the plants their green color is the chlorophyll that is in the chloroplast.

Explanation:

Given:

Brown allele (B) is dominant over the white allele (b).

It will be assumed that the alleles are not related to the X and Y chromosomes.

See attached diagram for details of the general case (for both homo-zygous and hetero-zygous parents)

For both parents hetero-zygous,

P1:

Genotype: Bb (100%)

Phenotype: brown (100%)

F1:

Genotypes : BB, Bb, bB and bb in equal proportions, i.e.

BB (25%), Bb (50%), bb (25%)

Phenotypes: 75% brown (from BB and Bb), 25% white (from bb)
