Each of two parents has the genotype green divided by brown​, which consists of the pair of alleles that determine eye color​, a
Liula [17]

Answer:

A)BB-Bg-Bg-GG

B)The probability is 25%

C)The probability is 75%

Explanation:

In order to solve this you just have to create a punnet square, where the parents are shown to both have brown and green coloured eyes genes, so it would be like this:

               Mother:      Brown                                 Green

Father↓  

Brown                      Brown-Brown                 Brown-Green

Green                      Brown-Green                  Green-Green

As the instructions say that if any kid had one green allele that would be the dominant, only the Brown-Brown will show the fenotype, so there´s 1/4 chance to happen, or 25%, the other probability of having green eyes is 3/4 or 75%

What kind of viral replication cycle will most likely damaged host cells immediately
Verizon [17]

Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.


toxic enzymes that damage the host cell that are coded for in the viral genome

secretion of chemicals from the virus to the membrane of the host cell

replication of the viral genetic material within the host

lysis of the host to release new viruses

Using Grime’s Triangle as a framework, discuss how natural selection and trade-offs work to form the niche of species.
Jobisdone [24]

Natural selection affects the scope of the niche of a given species. Moreover, trade-offs are associated with differences in traits that also may affect the niche of a species.

<h3>Natural selection and trade-offs </h3>

Natural selection refers to the differential survival or reproduction of individuals in particular environmental conditions.

The different niches occupied by species are mainly a consequence of differential trade-offs among species, i.e., by differential phenotypic features that generate negative correlations among species.

Grime’s Triangle is based on the associations (trade-off) between adaptation to productivity and/or competition, stressful environments (habitats) and disturbance.
