Answer:
genetic trait=eye color (a)
environmentally influenced trait=the language you speak (b).
The position of the Earth in the solar system and more regional effects, such as carbon dioxide levels, all play a role in the causes of ice ages. Thus, option A is correct.
<h3>
What are factor that involve in ice age on earth?</h3>
When the orbital cycle turns back, these feedbacks—involving the spread of ice and the emission of greenhouse gases—work in reverse to warm the Earth once more.
A prolonged period of cooling of the Earth's surface and atmosphere is known as an ice age, which is marked by the development or presence of polar and continental ice sheets as well as alpine glaciers.
Flooding has increased along the U.S. coastline as a result of the warming, rising, and acidifying of the seas.
Therefore, The Earth is currently facing an ice age.

Cohesion: When water molecules stick to one another through cohesion, they fill the column in the xylem and act as a huge single molecule of water (like water in a straw). Capillary action: Capillary action is the movement of a liquid across the surface of a solid caused by adhesion between the two.
American prairie, bison and badgers don't live in any of the other options naturally.
It is necessary to measure air pressure because it gives an idea about the amount of gases dissolve in water, the density of air at a particular place,the direction of winds etc.
Explanation:
- The pressure exerted by the total volume of air in the Earth's surface is called air pressure. It is also called barometric pressure.
- The air pressure decreases with decrease in air density and increases with increase in air density.
- With increase in air pressure more oxygen is dissolved in water.
- The direction of winds on Earth is also determined by the pressure belts. The winds move from region of high pressure to low pressure. Thus, measurement of air pressure helps in weather forecast.
