If a man and a woman, each with sickle-cell trait, were planning to marry, what information could you provide them regarding the
kiruha [24]

Answer:

I'll inform them that the possibility of all their future children/offspring being phenotypically sickle-celled is very high.

Explanation:

Sickle cell is an inherited disease condition in which the red blood cells of the blood loses its shape and hence, dies or gets broken down. It has to do with the blood genotype of an individual. There are three major types of blood genotypes in humans namely: AA, AS, and SS. SS is the recessive genotype that codes for the sickle cell trait.

Hence, a human with the sickle cell trait has a genotype- SS. Therefore, according to this question, a man and a woman, each with sickle-cell trait (SS), were planning to marry, This will mean that both the man and the woman will always produce a gamete with S allele, which will combine to form an SS offspring. In other words, all of the offsprings of this man and woman will be sickle-celled.

Suppose the North American plate is moving away from the Eurasian plate at a rate of 2 cm per year. The eastern-most point of No
Archy [21]

The correct answer is - 1,180 km.

North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.

To get to the result we only need to multiply the number of years with the annual movement

2 x 200,000 = 400,000

Than divide the result with 100,000, as that is how much cm are in one km

400,000 / 100,000 = 4

And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.

The base pairs are found in the _ of the DNA molecule
dybincka [34]

Answer:

Base pairs are found in double-stranded DNA and RNA, where the bonds between them connect the two strands, making the double-stranded structures possible. Base pairs themselves are formed from bases, which are complementary nitrogen-rich organic compounds known as purines or pyrimidines.
