A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth. the difference mitosis does in plants & animals is Plant and animal cells both undergo mitotic cell divisions. Their main difference is how they form the daughter cells during cytokinesis. During that stage, animal cells form furrow or cleavage that gives way to formation of daughter c

The causitive agent of the cohesion-tension model of xylem transport is transpiration. During the process of transpiration, water vapor is lost from the stomata of the leaf. To replace this water, water from adjacent cells is withdrawn. The water molecules stick together due to cohesion and are transported upwards through the stem in the form of a stream.<span />
Answer:
318,6 ms-1
Explanation:
Como sabemos que la relación entre la velocidad del sonido en el aire y la temperatura viene dada por;
V = 331√T / 273
Dónde;
V = velocidad del sonido
T = temperatura en kelvin = (-20) + 273 = 253 K
V = 331√253 / 273
V = 318,6 ms-1
