If a cell with 36 chromosomes undergoes mitosis, how many chromosomes will each of the two new cells have?
andrew11 [14]

Answer: 36 chromosomes

Explanation: Mitosis is a type of cell division that occurs in somatic or body cells. In mitosis, and a cell undergoes division to produce two daughter cells each with the same number of chromosome as the parent cells. Mitosis produces diploid cells and diploid cells are cells that have the same number of chromosomes as the parent cell. Diploid cells have two complete sets of chromosomes. For example in humans, somatic cells with 46 chromosomes undergo mitosis to produce two daughter cells each with 46 chromosomes.

Normally, the hydrostatic pressure difference between capillary fluid and interstitial fluid favors movement of fluid __________
timofeeve [1]

Answer:

out of

into

Explanation:

As pressure exerts force, Hydrostatic pressure is a type of force that occurs in fluid e.g (interstitial fluids) on the walls of the capillary. The helps to carry fluid-like materials out of the tissue capillary. There are quite bunch of relative factors affecting the hydrostatic pressure which include; the liquid density and distance beneath the liquid surface,force of gravity.

On the other hand, The protein osmotic pressure difference between capillary fluid and interstitial fluid normally favors movement of fluid into a tissue capillary. This protein substances consist of albumin, plasma protein etc. From our knowledge of osmosis as well, we knew it is the movement of substances through a semi-permeable membrane from the region of higher concentration to a lower concentration.  Therefore the protein osmotic pressure bring about movement of fluid like substances into the tissue capillary.
