Answer:
Any somatic cells in a diploid eukaryotic organism will have the diploid number (2n) of chromosomes. For humans that number is 46
Answer:
all cells have 23 pairs and 46 all together it does not matter what cell it is always the same amount other wise they whold say every cell has a diffrent amount
Explanation:
A) Meiosis I brings together sister chromatids, and meiosis II separates them.
B) Meiosis I separates tetrads, and meiosis II separates sister chromatids.
C) Meiosis I separates sister chromatids, and meiosis II separates tetrads.
B) Meiosis I separates tetrads, and meiosis II separates sister chromatids.
A) They permit digestive end-products to make
contact with body cells.
B) They permit exchange between the external
atmosphere and the circulatory system.
C) They transport gaseous cellular wastes from
body cells to the lungs for excretion.
D) They regulate the amount of ammonia and salt
dissolved in body fluids.
The function of the respiratory passageways in humans is to permit the exchange of gases, mainly oxygen and carbon dioxide, between the body and the external environment through the process of respiration.
The main function of the human respiratory passageways is primarily to permit the exchange of gaseous substances, namely oxygen and carbon dioxide, between the body and the external atmosphere. This is achieved through a process called respiration.
When we breathe in, oxygen from the air gets filtered and warmed in the respiratory passageways and reaches our lungs. It then gets transferred to the bloodstream. On the other hand, the carbon dioxide, a gaseous waste product of our body cells, moves from the bloodstream to the lungs, gets expelled through the respiratory passageways when we breathe out.
It's worth mentioning that the other options such as allowing digestive end-products to touch body cells or regulating the amount of ammonia and salt in body fluids are not direct functions of the respiratory passageways.
