Answer;
True.
When the northern part of the earth is farthest away from the sun it gets cold and the other side of the earth gets warm / summer
Explanation;
The Earth's orbit is not a perfect circle, but a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away.
When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, because the Earth is tilted on its axis.

b.an increase in oxygen levels in the blood
c.a decrease in the rate of cellular respiration
d.an increase in carbon dioxide levels in the blood?
Answer: The correct answer is D) An increase in carbon dioxide level in the blood.
During exercise, contraction of muscles take place very quickly as they work harder during exercise. As more oxygen is required to burn calories efficiently, the demand for oxygen supply increases.
When we start exercising, body temperature increases as the rate of cellular respiration also increases.
An increase in carbon dioxide in the blood causes increase in heart rate as there is more demand of oxygen for efficient contraction of the muscles.
Artery and veins are the blood vessels responsible to carry oxygenated and deoxygenated blood respectively. The innermost layer of these blood vessels is referred to as tunica interna.
Blood vessels are responsible for circulating blood from heart to other body parts and vice-versa.
These carry oxygenated blood from heart to other cells and deoxygenated blood from cells to lungs and then to heart.
These are of two types, namely artery and vein.
The innermost layer of an artery or vein is referred to as the tunicainterna.
Thus, the correct answer is tunica interna.
