Hepppp!!! The American curl is a type of cat with curled ears. A single gene with two alleles codes for the ear-shape trait. The dominant allele (R) codes for curled ears, and the recessive allele (r) codes for straight ears. If two curled ear cats produce a kitten that has straight ears, what is the genotype of the parent cats? a Rr x Rr b RR x RR c RR x Rr d Rr x rr

Answers

Answer:

Rr Rr

Explanation: The parents of the cat have to have an R allele to be a curled cat, but they can't be RR because that is a dominant gene, meaning that the recessive trait cannot happen. This means that the parents have to have a recessive trait, which means that they are heterozygous.

Which of the following is a property of life shared by prokaryotic cells and eukaryotic
cells, but not viruses?

Answers

Answer:

Explanation:

. The ability to process energy through metabolism. viruses cant reproduce without a host cell either

Viruses do not possess the tendency to process energy via metabolic reactions.

Difference between viruses and other cells:

Viruses are acellular, that is, they do not comprise any cellular organelles, and fail to divide and grow by its own.

Due to this viruses fail to carry out any kind of metabolic reactions, on other hand, prokaryotes and eukaryotes possesses the tendency to perform independent metabolism.

As viruses are not cells, they can only replicate and assemble within a living host cell, which can be a prokaryote or an eukaryote.

Thus, viruses cannot carry any kind of metabolic reactions while prokaryotes and eukaryotes can.

Explanation:

Nitrogen-fixing bacteria in soil can convert excess nitrogen into nitrates, which can contaminate groundwater.

A cone of depression forms around a well when the water table begins to slope toward the well.

The water in an artesian well comes from a confined aquifer.

A well not only has to reach the water table but also has to go deeper.

Unconfined aquifers are more prone to pollution.

The two primary components of a septic system are a septic tank and a drainage field.

Groundwater that comes to the surface naturally is spring.

Answers

Answer:

Founder effect.

Explanation:

The founder effect is a case of genetic drift in which a small population sample of a limited number of individuals is shed from a larger population, its gene pool carrying only a part of the genetic diversity represented in the source population. Thus, it is likely that the genetic destinies of the population of origin and of the new population are established in different ways. When a new generation has randomly distributed alleles, with a large enough sample size, we can expect that the gene pool of the new generation will more or less represent the gene pool of the previous generation.
