DNA only replicates once in either mitosis or meiosis. I guess you mean how many times a pair of sister chromatids are separated. Still, once for either of them. The only difference between mitosis and meiosis is that mitosis forms 2 identical daughter cells with diploid number of chromosomes in a single 'split'.
Answer:
a = increased temperature increases the kinetic energy of the gas molecules.
b = higher temperatures will increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.
The endocrine system is made of glands that secrete hormones. These hormones help regulate the organs and cells activity. The hormones among other things control your metabolism.
Explanation:
How widespread is asexual reproduction in planets an compared to animals which methods of asexual reproduction occur in both animals and plants
One big reason for this is because individuals of the same species often have to fight over shared resources (this means shared food and shared environment).
Because they fight over a limited amount of space and food, competition between individuals within one species can be present and very tough.
On the other hand, having members of different species also possibly means different territories and different food sources. A lion has no quarrel with dolphins, while it can have a lot of fights with lions from different prides (large group of lions).
