Answer: number of daughter cells per cell
Explanation: The process of meiosis give rise to four daughter cells that are haploid, that is, they contain half the number of chromosomes of the diploid parent cells. In the process of mitosis, two daughter cells are usually produced.
Answer:
The circulatory system comprises of blood vessels which help in removing carbon dioxide from the body. The carbon dioxide produced by the cells is collected by the capillaries where the carbon dioxide gets dissolved in the blood. This blood is carried to the heart via the veins. The heart pumps the deoxygenated blood to the lungs where gaseous exchange occurs between the blood capillaries and the alveoli of the lungs. When we exhale, the carbon dioxide is breathed out.
Answer:
pressure gradient
Explanation:
The correct answer would be pressure gradient.
<em>A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.</em>
In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.
