Answer:

Goal of meiosis: To produce gametes with half the number of chromosomes as compared to the somatic cells.

Each parent cell produces four daughter cells by the end of meiosis.

Explanation:

The goal of meiosis is to produce gametes for sexual reproduction. Since male and female gametes fuse to produce a zygote, each of the gametes should have half the number of chromosomes as compared to the somatic cells to prevent the doubling of chromosomes by the end of each round of sexual reproduction.

Therefore, meiosis produces haploid gametes from diploid gamete mother cells. Absence of DNA replication between meiosis I and meiosis II ensures that the number of chromosomes is halved in the daughter cells of meiosis. Additionally, meiosis also imparts genetic variations to the progeny by the process of crossing over.

A diploid parent cell enters meiosis I and produces two haploid daughter cells which in turn enter meiosis II to produce a total four haploid daughter cells.

Fluorine (F) has seven electrons in its outter most shell. Flouride ?

Ainat [17]

Answer:

Fluoride theoretically should have 8

Explanation:

Fluoride is the Fluorine ion, meaning electrons are added or substracted from Fluorine to form Fluoride. Usually, an ion has a full outer shell.

olya-2409 [2.1K]

Answer:

The correct option is 3. "At pH 6.5 the enyzme is 50% active"

Explanation:

For the titratable group to be protonated and cause the enzyme to be in the active state, it needs to have gained a hydrogen cation (H+). In order for that to happen, there must be enough hydrogen cations in the environment of the enzyme, and hence, an acidic pH is required in this case.

NikAS [45]

Answer:

Evolution

Explanation:

Evolution – change over time. It is the process by which modern organisms have descended from ancient organisms. Current scientific facts, observations and hypotheses all combine to create current evolutionary theory – which is a well-supported, testable explanation of the biological diversity on Earth.
