Hello
all the options that have been presented are involved in meiosis but two of those are also involved in mitosis.
so in meiosis, germ cells (diploid) are being divided into 4 haploid daughter cells that are genetically different. it goes through two rounds of division and each time they go through prophase, metaphase, anaphase, and telophase.
in mitosis, a somatic cell (diploid) becomes 2 genetically identical diploid daughter cells. it goes through one cycle of division which involved prophase, metaphase, anaphase, and telophase.
as we can see, the three options that apply to meiosis but not mitosis are:
it generates genetically different cells
it generates haploid cells
it involved two rounds in nuclear division
hope this helps
have a nice day :)
<u>Answer</u>:
The activation of parasympathetic nervous system results in the relaxation of the GI tract.
<u>Explanation</u>:
Parasympathetic nervous system helps the brain to understand that the danger is now over and it can relax. Hormones named corticotropin and adrenocorticotropin which are realising the body to start working against danger is now going to be relaxed with relaxation of parasympathetic nervous system. This is how sympathetic and parasympathetic nervous system works together co-ordinate together in fight or flight mechanism of the nervous system.
The body fight or flight response is under the control of sympathetic nervous system, which is one part of autonomic nervous system. The another part is parasympathetic nervous system that relaxes and slow down the body's response.
J-shape curve
J-shape curve is a curve that shows the population density of an organisms as they increase rapidly in a logarithmic or exponential form but abruptly stops due to environmental resistance. Thus, the population rate is largely determined by the biotic potentials and size of the population. However, exponential growth produces J-shaped curve.
