Meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or n) from parental cells with two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, producing a diploid zygote (2n). The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation.
<span>In sexual life cycles, meiosis and fertilization keep the number of chromosomes constant from generation to generation. </span>
Each of the resulting daughter cells will have 64 chromosomes.
Mitosis is one of the components of the cell cycle when the duplicated chromosomes are distinguished into two nuclei. In mitosis, the two resulting daughter cells will always comprise of the similar quantity of chromosomes as the parent cell from which they are obtained.
The main function of mitosis is to keep the number of chromosomes constant in each cell division, thus, permitting one to grow and self-sustain the bodies.

Answer:
Umami identifies foods that might contain essential amino acids.
Explanation:
You may have heard that our taste buds can recognize the four basic tastes: sweet, salty, sour and bitter. But what many still do not know is that the human taste recognizes one more taste - the "umami".
Umami is recognized by our taste buds when we eat foods that contain substances called aminoacids. The umami flavor is composed of three main substances present in various foods: glutamate, inosinate and guanylate. The ability to recognize umami taste is an evolutionary advantage of humans that represents the ability to identify foods that may contain essential aminoacids.
