Answer:

The diagram is not attached but the question can be solved with the question alone, since the necessary information was provided.

• D. Offspring D (ff EE)

Explanation:

This is a cross involving two genes in mice. The two parents mice are crossed to produce four offsprings. The genotypes of the parents mice are FFEe (black fur) and ffEe (white fur).

These two parents will produce the following allelic combinations of gametes;

FFEe- FE, Fe, FE, Fe

ffEe- fE, fe, fE, Fe

Using these gametes in a pumnet square (see attached image), 16 possible offsprings will be produced with only three (3) distinct genotypes viz:

FfEE (4/16)

FfEe (8/16)

Ffee (4/16)

Hence, based on this question, all of the offsprings except offspring D (ffEE) is likely to be produced. This means that the offspring with genotype ffEE is the imposter as the parents mice with genotypes FFEe and ffEe could not have given birth to such offspring.

A study is being done to test the effects of habitat space on the size of fish populations. Different sized aquariums are set up

olga_2 [115]

Answer:

On the basis of the given information, the six goldfish are taken in distinct sized aquarium to examine the influence of habitat space on the rate of survival of the fishes. The kind and amount of food, cleanliness, and temperature are maintained similarly.

Thus, with the help of the information one can state that:

A. The size of the aquarium is the independent variable.

B. The number of fish survived after six months is the dependent variable.

C. Water temperature, the kind of amount of food, maintenance, and cleanliness of aquariums are the controlled variables or the constants.

In the controlled experiments, there are dependent and independent variables. The independent variable will get modify generally and is compared to the control. The variable, which is determined in an experiment is considered as the dependent variable. It relies upon the independent variable of the experiment. The control group in an experiment is created similar in each circumstance in an experiment. The control group is the one, which is compared with the experimental group.

In which type of front is the flow of air on both sides of the front almost parallel to the line of the front?

lisabon 2012 [21]

Answer: the answer is B which is stationary

Explanation:

This type of front behaves like a warm front only that it is quiescent because the front barely shifts its position. The weather may also be similar to that of a warm front. The two abutting air masses run almost parallel to the front because none is stronger than the other to cause displacement.

Yes because brown eyes are a dominant gene while blue is recessive gene so one of both of the parents ancestors had to have them for her to be their biological daughter.
