Which cell division, mitosis or meiosis, does fertilization? Explain what fertilization is.

Biology

Firlakuza [10]3 years ago

This is kinda a weird question for me to answer... BUT.... lol

I think it is Meiosis, which occurs over two cycles of cell division, which sperm cells complete before fertilization. It also is the process that creates gametes -- sperm and egg cells -- containing only one, or a haploid, set of chromosomes.

And fertilization is the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote... OR

it could be the action or process of applying a fertilizer to soil or land.

Hope this helps. c;

IRISSAK [1]
Answer:
Letter E - exons are cut from the strand and removed

Explanation:

Letter A and B are incorrect because the poly-A tail and guanine cap are added to the 3’ and 5’ end respectively. They aid in translation of the mRNA, while serving as protection. The poly-A tail is repeated adenine nucleotides, while the guanine cap is a modified guanine nucleotide.

Letter C is incorrect because alternative splicing is one mechanism for generating variation, and is thought to be one of the reasons for why humans have smaller genomes than other organisms and still maintain high complexity. Alternative splicing is incredibly important because it produces more than one transcript from a pre-mRNA.

Letter D is incorrect because introns are the non coding portions of the mRNA. They are excised to make a smaller mRNA transcript, and one that contains all the protein genes.

This letter E is the correct answer, because exons are the coding portions of the mRNA, and are not excised during RNA processing.

Hope that helped! If I made a mistake, please let me know.

Is human survival independent of other species?
wolverine [178]

Explanation:

As far as I can think of, we're dependent on other species. If we can't be carnivores, then literally, the only other option I can think of is being a herbivore, and that still an organism. We need sufficient life essence to keep living. We CANNOT live without harming another organism.

In short of my babbling, human survival is not independent of other species.
