Answer:

This change in skin color provides evidence that the environment can influence gene action.

Explanation:

Many studies have revealed that the physical traits of a person are attributed to the genetic makeup as well as the environmental characteristics. Some traits depend on both the factors. Environmental factors can determine which genes would be turned on or off or it might control the expression rate of a gene.  For example, two identical twins might have different skin colour if one works in sunlight and the other works indoors.

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.

Why rapid binge drinking is more dangerous than slower consumption of alcohol?
Tpy6a [65]
The same way we never inject a full bag of anything quickly and intravenously. Your body would not be able to compensate for the amount of the substance. Alcohol or more importantly the Ethanol or Ethyl Alcohol in alcoholic beverages is the active ingredient of such beverages. It is also a drug called a CNS (Central Nervous System) depressant which means it is in the same class category of Opioids (Such as Heroin and Morphine) and Barbiturates (Rophynol). Your body processes alcohol via the liver, as it is also considered a toxin. By consuming a massive amount of alcohol without spacing it out, you will overload your system, not only literally overwhelming your liver and causing Alcohol Poisoning, but you also can go into a state similar to a Heroin overdose.

What does a S-shaped curve demonstrate for population growth?
11111nata11111 [884]

A design of growth in which (occurs only in a different situation), the population frequency of an organism rises gradually originally, in a good acceleration time, later progresses swiftly nearing an exponential growth pace just like the J-shaped curve, however, it later declines (meaning rejects) in a bad acceleration time till at zero growth rate the population maintains. For example, yeast is a tiny fungus, so tiny, a microscope is required to view it, furthermore, it is used to produce bread and alcoholic drinks, displays the traditional S-shaped curve if raised in a test tube. Its maturity levels off as the population deplete the nutrients that are essential for its growth.
