Ber [7]

Answer:

It affects the oxygenation of the tissues in a negative way, that is, causing tissue hypoxias.

Explanation:

What will happen is that BPG, having a different relationship with deoxyhemoglobin, hemoglobin will not give oxygen to organs or tissues during glycolysis at times when the sympathetic nervous system is activated or even in the maintenance of physiological tissue vitality, therefore it will trigger a drop in the partial pressure of the gas both in the blood and in the tissues since they will be retained in the hemoglobin structure without being able to release it.

PtichkaEL [24]

The meselson-stahl experiment demonstrated that dna replication produces two DNA molecules each composed of the nitrogen isotopes.

<h3>What was the conclusion of the meselson-stahl experiment?</h3>

Based on observations and experimental results, Meselson and Stahl concluded that DNA molecules can reflect semi-conservatively. Investigation of semi-conservative nature of replication of DNA or the copying of the cells, DNA failed to cease there.

1958, Matthew Meselson and Franklin Stahl carried out an test on E. coli which divides in 20 minutes, to take a look at the replication of DNA. 15N (heavy) and 14N (normal) are isotopes of nitrogen, which may be outstanding primarily based totally on their densities through centrifugation in Caesium chloride (CsCl).

Human gametes should contain chromosomes each. This number would be considered the
Sophie [7]

Answer:

Human gametes should contain <u>23 </u>chromosomes each. This number would be considered the <u>haploid </u>number for humans. The symbol for this is <u>n</u>.

Explanation:

Gametes are an organism's reproductive cells. Female gametes are called egg cells, and male gametes are called sperm.

In most organisms, somatic cells (all cells except for gametes) are diploid, whereas the gametes tend to be haploid. Haploid cells have a single set of chromosomes, while diploid cells have two sets of chromosomes.

When it comes to human cells, somatic cells have 46 chromosomes. This means that each gamete has 23 chromosomes. This is called the haploid number and is marked by a lowercase <em>n</em>. This number refers to the total number of chromosomes found in a gamete (for human cells n=23).
