In The Punnett Square Fill In The Shaded Boxes With The Alleles Of Each Parent Use B For The Dominant

Answers

Answer 1

Answer:

Explanation:

Under the male put BB

Next to the female bb

then first row should be Bb Bb

second row should Bb Bb

Answer 2

Here, all the alleles of the black parent are dominant and are represented as BB, and those of the white parent are represented as bb, and they both are purebred dominant and recessive alleles that have produced all dominant black (Bb) offspring.

What is Punnett Square?

A Punnett square is a diagram used to predict the possible outcomes of a genetic cross between two parents. In this case, the parents have different alleles for a gene that determines the color of their fur. The dominant allele B produces black fur, while the recessive allele b produces white fur. The Punnett square is arranged in a grid, with each box representing one possible genotype for the offspring. The top row and left-hand column of the grid represent the alleles that each parent can contribute to their offspring. In this case, both parents are purebred,as expressed below.

Hence, black parents are dominant and are represented as BB, and those of the white parent are represented as bb, and have produced all dominant black offspring.

If two individuals were heterozygous for freckles, which are a dominant autosomal trait, what percentage of their offspring would you expect to have freckles

Answers

Answer:

75%

Explanation:

Firstly, an autosomal dominant trait is a trait the becomes expressed in the presence of only one affected allele, which is the dominant allele. Freckles is said to be an autosomal dominant trait meaning that the presence of the dominant allele (F) makes a person have the condition.

According to this question, If two individuals that are heterozygous for freckles cross i.e. Ff × Ff, the following proportion of offsprings will be produced: FF, Ff, Ff and ff (see punnet square).

From the genotypic observation of the produced offsprings:

FF, Ff - possess freckles

ff - do not possess freckles

Since, 3 (FF, Ff and Ff) of 4 offsprings possess freckles, the percentage of offsprings expected to have the condition will be:

3/4 × 100 = 75%

Is the cell an open or closed system? Explain your
answer using at least one example of a cell
organelle and its function

Answers

·         In an open system matter and energy can be transferred

·         In a closed system only energy can be exchanged

·         In an isolated system neither matter nor energy can be exchanged

·         The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system

·         As an open system the cell allows nutrients to enter the cell and waste products to exit the cell

·         The cell does this through the use of a semi-permeable membrane

·         It needs nutrients in the forms of glucose, ions and many other molecules.

·         The nutrients can come into the cell through either passive or active transport

·         In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.

·         During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.

Right atrium, right ventricle, lungs, left atrium, left ventricle, body.

Answers

Answer:

answer is D

l

Explanation:

Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

The statement that describes the order blood flows through the body and the heart is:

Right atrium, right ventricle, lungs, left atrium, left ventricle, body.

What is blood?

It is a red liquid with different shades that varies according to the amount of oxygen it has inside, that is, hemoglobin.

Characteristics of blood circulation

It is a necessary substance for oxygenation to occur between cells, as well as to regulate blood pressure.

Each side of the heart is divided into an upper chamber called the atrium and a larger, lower chamber called the ventricle.

The blood flows since it has left the right ventricle, has been oxygenated by the lungs and has returned to the left atrium through the pulmonary veins, it is carried to the left ventricle.

Therefore, we can conclude that the main function of the blood is to ensure that oxygen and nutrients are distributed between the cells of each organism.

Answers

Answer:

They would instead focus on controlling and diminishing the rodent population.

Explanation:

They would instead focus on controlling and diminishing the rodent population. The best solutions are always those that target the cause of the problem. Therefore, since the cause of the virus are rodents and that is how the virus spreads, then targetting the rodent population would be the best choice. The scientists would have to figure out a way of keeping track and controlling where the rodent population moves, as well as figuring out how to control their reproduction and diminish their population size. All of this while also trying to predict the possible effects that the population size can have on the environment.

Describe the thickness of the uterus lining during
menstruation process.

Answers

Answer:

As the cycle progresses and moves towards ovulation, the endometrium grows thicker, up to about 11 mm. About 14 days into a person's cycle, hormones trigger the release of an egg. During this secretory phase, endometrial thickness is at its greatest and can reach 16 mm.

Explanation:

Answer:

During this timeframe, the uterus is in the proliferative phase. Estrogen induces growth of the functional layer of the endometrial lining, which enables it to grow from about 1-3 mm post cycle to 6-8 mm approximately. Days 12-16 of the menstrual cycle At this point, the endometrial layer is about 6-8 mm thick.
