Why must meiosis and not mitosis be used to produce gametes?

1 answer:

3 0

This is because meiosis divide the total chromosomes number by half its original number (2n/2 = n) which would be combined with the haploid egg cell to produce a diploid (2n) zygote white mitosis maintains the chromosome number.

Wil the car smoother and more pleasant.

Pavel [41]

Answer:

C). Buffers

Explanation:

The given analogy can best be completed with 'buffers' as it similarly compares with the 'solution pH' like the comparison between 'shock absorbers' and 'vehicle movement.' Like the 'shock absorbers' function to help in improvising the vehicle movement and ride quality by lowering the effect reverberations of traveling on a rough platform, similarly, the 'buffers' help in regulating the 'pH of a solution.' Thus, option C is the correct answer.

Create a Venn diagram comparing prokaryote and eukaryote cells plz help

GuDViN [60]

Prokaryotes: the simplest and oldest form of life, single celled, start of live/where all life came from, they can live in any environment on Earth, bacteria are the only prokaryotes. They DO NOT have a nucleus. Tails help them move along with little hairs around the cell. No organelles, they have circular chromosomes, they're unicellular or colonial, they have a cell wall and cell membrane.

Eukaryotes: Have a nucleus as well as organelles, linear chromosomes, have a cell wall (plants&fungus), have a cell membrane.

Hope I was able to help! :)

miv72 [106K]

Answer:

This question lacks proper arrangements but one can understand and chip in the appropriate terms. The terms missing there in order, which answers the question are:

Nucleus

Transcription

RNA polymerase

mRNA

Ribosome

Explanation:

The cellular process being described in this question is GENE EXPRESSION, which is the expression of the information contained in the genetic material in order to produce useful gene products (proteins). The genetic material (DNA) is stored in the nucleus of eukaryotic cells. The first process of this gene expression called TRANSCRIPTION involves the copying of the information contained in the DNA into an RNA molecule.

Transcription is carried out by an enzyme called RNA polymerase, which synthesizes a complementary strand of mRNA from a DNA template. mRNA ia called messenger RNA and it acts as a conveyer/carrier of this information present on its nucleotides out of the nucleus into the cytoplasm, specifically the site of protein synthesis called RIBOSOME.

The RIBOSOME is a cellular organnelle where the other process of gene expression called TRANSLATION will occur.
