She could use a control to compare her data to and make sure it is cleaner. Ex. Use the old detergent on ten shirts and then use the new detergent on another ten shirts. She would then compare the shirts she did each detergent on and come up with her conclusion.

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%

masha68 [24]

Answer:

<em><u>The answer is</u></em>: <u>Folded, fault block, volcanic.</u>

Explanation:

<u>The main types of mountains are</u>: Folded, fault block, volcanic and upwarped.

Folded mountains. These types of mountains tend to change constantly depending on their complexity, however they always conform to the basic type.

Volcanic mountains. It is about the mountains that come to form when a volcano erupts.

Domes. These mountains are created by domed strata, as a granitic intrusion is generated.

Mountains in block. These are large-scale structural failures. These inside are usually folded and tend to have failures.

Plateau mountains. These are created when there is activity in the deepest of the earth's crust. They are formed with the deep channels that the current water produces, where the rivers can cut any table regardless of their depth, thus producing high-rise mountains.

<em><u>The answer is</u></em>: <u>Folded, fault block, volcanic.</u>
