Answer:

The process which must occur when intending to work with research animals that are covered by the U.S federal regulations is ethical review and approval

Explanation:

Some animals had been threatened of extinction due to inconsiderate usage and killings due to either commercial, food, or research purpose. The U.S government, therefore, to prevent the extinction of such animals, formulated a law to restrict the engagement of these animals, even in research if the research will involve the slaughtering, injuring, or alter the physiological functions of the subject animals. Therefore, there has been needing to undergo a compulsory ethical review process when planning to undertake research. This process will objectively review the aims and objectives of the intended research, the methodology involved in achieving the aim, as stated in the research proposal. The importance of this review is to determine if the research will have deleterious effects on the animals, both spontaneously and in the future.

choli [55]

Answer:

1/64

Explanation:

The following genotypes were crossed: AaBbCc X+Xr and AaBBcc X+Y

If we asume that the autosomal genes are in different chromosomes, then they will assort independently during meiosis and gametogenesis. In that case, we can use the Multiplication Rule of Probability to obtain the probability of having a specific genotype in the progeny.<u> This rule states that when two or more events are independent, the probability of all them happening at the same time will be the result of the multiplication of the individual probabilities of each event.</u>

<u />

We can separate each gene in the cross to determine the genotypic ratios in the offspring, and then multiply the probabilities of the aaBbCc X+X+ genotypes to obtain the overall probability of having progeny with that genotype.

<h3><u>Aa x Aa </u></h3>

1/4 AA

2/4 Aa

1/4 aa

<h3><u>Bb x BB </u></h3>

1/2 BB

1/2 Bb

<h3><u>Cc x cc </u></h3>

1/2 Cc

1/2 cc

<h3><u> X+Xr x X+Y</u></h3>

1/4  X+X+

1/4  X+Y

1/4  X+Xr

1/4  XrY

The probability of having offspring with the aaBbCc X+X+ genotype will be: 1/4 × 1/2  × 1/2  × 1/4 = 1/64

Convergent plate boundary: how do the plates and mantle interact?
vredina [299]

Answer:

Convergent plates collide causing earthquakes and volcanoes, and creating mountains.

Therefore second answer, The plates move towards each other at these boundaries and the more dense plate will sink under the less dense plate into the mantle where it is destroyed. (This creates a trench.)

Explanation:

In the lithosphere the plates melt when they go down.

!!!

Remember:

Convergent = Collide

Divergent = Divide

Transform = Slide
