Answer:

For DNA replication to occur, the two chains that form it must be separated, each with a specific base sequence that serves as a template for the coupling of complementary nitrogen bases, that is, adenine with thymine and cytosine with guanine, attending to the base pairing rules.

Explanation:

Base pairing rules is the way in which nitrogen bases are matched in the double strand of DNA during replication, which occurs by <u>binding a purine with a pyrimidine</u>.

The DNA contains sequences of 4 nitrogen bases, two purines and two pyrimidines. Pyrimidines are cytosine and thymine, while purines are adenine and guanine. Adenine should bind thymine and cytosine with guanine, according to the rule. When the bases are paired, they form hydrogen bonds between them, two for Adenine-Thymine and three for Cytosine with Guanine.

The relationship between the two strands of DNA is that one complements the other, due to the complementarity of their bases.

<u>DNA replication is semi-conservative</u>, since by separating the two chains one serves as a template for a new chain to be formed, by pairing complementary bases. The final result is two DNA molecules, each with an original chain and new one.

Vlad1618 [11]

When a solution, in this case water, is cold, the solute (salt) doesn’t mix thoroughly. By increasing the temperature of the solution, the solute can be dissolved. So Gabriel needs to heat the water to make the salt mixture dissolve properly.

Why should one gargle with salt water to help soothe a sore throat?

Sore throats are often caused due to viral infections, like cold or the flu. Sore throats caused by viruses often resolve on their own, whereas sore throats caused by bacteria require addition treatments like antibiotics and home remedies like gargling with salt water.

Gargling with warm salt water is often recommended for sore throats as it soothes the inflamed membranes of the throat, preventing further thickening. Also because salt aids in destroying bacteria, the salt water remedy is a great natural method for temporary resolvement.

When sperm and egg cells undergo meiosis, the number of chromosomes goes from ______ to _______. When an egg is fertilized by a

Lana71 [14]

Answer:

2n to n, n to 2n

Explanation:

Meiosis is known as reductional division because in meiosis the chromosome number gets reduced to half in daughter cells so when sperm and egg cells undergo meiosis than the chromosome numbers get reduced from 2n to n. In humans, the chromosome number is 46 and it gets reduced to 23 after meiosis.

When egg is fertilized by the sperm than the two chromosomes comes in the same cell and the number goes from n to 2n that mean in human it goes from 23 to 46.

if a zebra migrates to join a different herd of zebras is that mutation gene flow genetic drift or natural selection?

jenyasd209 [6]

Answer:

The correct answer would be gene flow.

Explanation:

Gene flow is explained as the transfer of genes from one population to another so there is an increase in their frequency of genes.

It is also called migration. The addition or loss of people can affect the frequencies of the gene pool even if no other evolutionary mechanisms working at the time.

Thus, the correct answer would be gene flow.
