Answer:
The four seasons happen because of the tilt of the Earth's axis. At different times of the year, the sun's rays hit different parts of the globe more directly. The angle of the Earth's axis tilts the Northern Hemisphere towards the sun during the summer.
Explanation:
Answer:
Because of the difference in surface area to volume ratio
Explanation:
Surface are to volume ratio is the area of an object that is exposed to the external environment (surface area), compared to the amount within an object (volume).
Therefore an elephant has a lower surface area to volume ratio than a mouse.
The smaller an object is the greater its surface area to volume ratio.
Small animals have much more surface area per mass than large animals. With so much surface area, they lose heat very quickly. So, a mouse, with a lot of surface area per mass, must spend a lot more energy to stay warm than a large animal.
It is C, because DNA has 2 pairs: a t and c g.
When translated into RNA, a pairs with u instead.
The answer to this question is hematocrit. Hematocrit is the
volume of red blood cells in the blood. Hematocrit is also known as packed cell
volume. Hematocrit levels of a person also notes health problems. When the level
of hematocrit is high it can cause sleep apnea, dehydration, COPD, and even
falling of plasma levels.
