It is TRUE that each lung is fed oxygen by a separate bronchus.

Humans respire through the use of lungs. Each human being possess two lungs and each lung has its own bronchi. The bronchi serve as the path for the movement of air from the nose / mouth to the alveoli in the lungs. The alveoli are surrounded by blood vessels and the oxygen from the outside enter the blood through the thin capillary wall of the blood vessels while the carbon dioxide is released to the outside through the same medium.

Snowcat [4.5K]
<span>While alien genomes may be constructed by completely different molecules (for example, silicon based life forms are a possibility rather than carbon) it is logical to assume that all life forms would have some sort of protective mechanism to prevent the degradation of DNA during replication. Essentially, to prevent mutations and rapid aging, DNA, alien or otherwise, would have some types of telomeres. They might either be long chains of repeated or irrelevant code or molecules that would not be easily corrupted.</span>

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.

Sedbober [7]

Answer:

This is an example of "Disruptive selection".

Explanation:

<em>Disruptive selection</em> occurs when <em>selective pressure</em> <em>favor homozygous</em>. In equilibrium, <em>the two alleles might be present or one of them might be lost</em>. If an environment has two extremes, then in these environments, both alleles are presented in homozygous.  

The disruptive selection causes an <em>increase</em> in the two types of <em>extreme phenotypes over the intermediate forms</em>. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.

Populations show two favored extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the <u>extremes forms</u>.  Individuals in <u>the middle</u> are not successful at survival or reproduction.

<em>Color</em> is very important when it comes to <em>camouflage</em>. Dark green caterpillars that live in dark foliage and light green caterpillars that live in light foliage can <em>hide from predators</em> more effectively and will live the longest. Intermediate colored green caterpillars that don't camouflage or blend into either will be eaten more quickly.

Where is dna located in a cell that is not going through cell division?
castortr0y [4]

Answer:

Actually, cell division is the mechanism by which DNA is passed from one generation of cells to the next and ultimately, from parent organisms to their offspring. During meiosis, the cells needed for sexual reproduction divide to produce new cells called gametes.
