Answer:

After one round of DNA replication, <u>none</u> of the DNA will contain only 14N, <u>none</u> of the DNA will contain only 15N, and <u>all</u> of the DNA will be of an intermediate density.

Explanation:

In order to rule out the conservative model of DNA replication and discover that it in fact a semi-conservative model, this technique was employed to check for what ratio of N15 and N14 was present in cells that had undergone the process of replication. The former would've resulted in equal densities of both N14 and N15.

Which of the following is a reason why cells divide? A.to maintain a surface area large enough to support their cytoplasm. B.to
Studentka2010 [4]
I think the correct answer from the choices listed above is option A. Cells divide in order to maintain a surface area large enough to support their cytoplasm. When they divide, their volume decreases which enables them to obtain enough nutrient and expel wastes.

What genotype is heterozygous for both shape and color dhybrid cross ry sequence
jenyasd209 [6]

Answer:

RrYy is the genotype that is heterozygous for both seed shape and seed color. The traits here we are discussing are pea plant's seed color and shape.

Explanation:

A dihybrid cross is a cross in which two traits are simultaneously being studied. Here there are two traits under consideration that are seed shape and seed color. The seed shape can be round or wrinkled and seed color can be yellow or green. The round seed  allele is dominant over yellow seed allele and the yellow color allele is dominant over green color allele.

As homozygous indicate both alleles of a gene are same in an individual and heterozygous condition indicates that both alleles of a gene in an organism are different.

Therefore the genotype of homozygous pea plants for seed color and seed shape can be RRYY or rryy respectively and genotype of heterozygous genotype will be RrYy respectively.

Hope it helps!
