1. Green, because it serves as a perfect camouflage against prey in vegetations.

2. It is a process whereby a breeder of animals or plant cultivator, chooses to breed between different species for their characteristics that are inheritable.

3. Mutations is an evolutionary process that helps a specie better adapt to their environment. DNA changes causes by mutation can help lighten or darken colour pigment. Like in the dark-coated mouse, where 9 changes to the DNA coding for color makes its fur lighter for better camouflaging.

Increasing the volume of air that reaches the alveoli and takes part in gas exchange will cause blood pH to:
Karolina [17]

Answer:

B. increase, because the partial pressure of CO2 in the blood will decrease.

Explanation:

The presence of carbon dioxide gas in blood imparts H+ ions due to its reaction with H2O and thereby, lowers down the blood pH.

When more air reaches alveoli, the rate of gaseous exchange is increased. More of the carbon dioxide is removed from the blood and is released out of the body via exhalation.

Removal of carbon dioxide from blood would increase the pH of the blood since the partial pressure of CO2 in the blood would decrease.

Use scientific language to describe two ways that fossils and embryos are alike.
Misha Larkins [42]

Answer:

Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos

How has waste leaving a cell affected its surface area to volume ratio?
lapo4ka [179]

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger and as volume increases, surface area to volume ratio decreases. The larger a cell, the less easily it can get rid of waste and it also has more trouble getting water, nutrients and gases in. That is why we do not see giant cells. Instead we see multiple cells in larger organisms.  

One way to increase surface area is to flatten the cell. That is why red blood cells are flat discs, instead of spheres. Another way is elongation. That is why many bacteria are rod shaped, and why neurons are elongated. In fact, the human body relies on the same principle to adapt to climate. Long tall and lean folks with long arms and legs live in East Africa, because such shapes increase surface area to get rid of excess body heat to avoid heat strokes. Europeans and Asians adapted to cold climates, in contrast, have shorter arms and legs and rounder torsos to minimize surface area. to conserve body heat.
