In certain rats, black fur is dominant over white fur, If two rats that are both heterozygous for fur colored are mated, what would their offspring be expected to have?

Answers

Answer 1

Answer:

Three different genotypes and two different colors

Explanation:

Because both rats have heterozygous genes, meaning they have 2 different alleles, ex: "Yy") The offspring can have different genotypes and colors because the parents have heterozygous genes.

hope this helps!

Answer 2

The offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

According to this question, a gene coding for fur color in rats is involved. The allele coding for black fur (B) is dominant over the allele for white fur (b).

If two rats that are both heterozygous for fur are crossed i.e. Bb × Bb, gametes B and b will be produced by both rats. Using this gamete in a punnet square (see image), the following offsprings will be produced: BB, Bb and bb.

BB - black offspringBb - black offspringbb - white offspring

Therefore, the offsprings of the cross between two heterozygous rats will have the following genotypes: BB (black), Bb (black) and bb (white).

Brackish water is when freshwater meets with sewer water or salty water.

Brackish water can be found in the mangrove swamps ecosystem.

They are marked by halophytic trees, shrubs and different flora thriving in saline to saline tidal waters.

What is the mangrove swamps ecosystem?

Mangrove forests, also named mangrove swamps, mangrove shrubs or trees, are formative wetlands that appear inshore intertidal zones. Mangrove forests grow mainly in equatorial and subtropical spaces because mangrove trees cannot resist freezing .

It is distinguished by such qualities as a damp climate, saline habitat, waterlogged soil or sludgy soil.

Thus, Brackish water can be found in the mangrove swamps ecosystem.

The first line of defense involves which structure(s)?
OT-cells

OB-cells

Answers

Answer:

skin

Explanation:

The skin is vital for our general health and well-being. In addition to acting as the body's first line of defense against bacteria and viruses, healthy skin also maintains fluid balance and helps regulate body temperature. She is very sensitive, she recognizes the slightest touch as well as pain.

As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.

Corals grow in dense groups on the floor of the ocean. Which type of distribution pattern does this represent, and what is the advantage of this distriubtion?

Answers

Answer:

Clumped distribution

Explanation:

Clumped distribution is a type of distribution in which organisms are clustered in groups. This is the most common form of distribution. Clumped distribution occurs in environment that are patchy (the patches are the part suitable for the organism to live in).

Clumped distribution is good because organisms have better protection from predators providing defense, and there is more access to food resources.

Since the Corals grow in groups on the ocean floor, hence it is a form of Clumped dispersions.

A. The bacteria would lose all their RNA.

B. The colony could not produce bacteriophages.

C. The colony would have less genetic variation

D. The bacteria in the colony could not reproduce.

Answers

The colony would have less genetic variation. The Bacteria in the colony would be too genetically similar

The bacteria living in a colony is aunable to perform the conjugation as they have less chances of survivial due to the colony is less genetically divere. Thus the option C is correct.

What is conjugation ?

This is a process wherein organism of the same species like the bacteria, exchange the nuclear mating materials during a temporary union and are capable of transferring one consent form from one organism to another. Thus the lack of genetic variation will lead to fewer chances of species survival.

Answers

Answer:

1. Cytokinesis

2. G1

3. S

4. Mitosis

5. Interphase

6. G2

Explanation:

This question is describing the phases in the MITOTIC PROCESS. Mitotic process is grouped into Interphase and Mitosis. The Interphase involves stages such as G1 (first gap phase), S (synthesis phase) and G2 (second gap phase) while mitosis consists of prophase, metaphase, anaphase, and telophase.

1. The stage where the cell divides into 2 daughter cells with identical nuclei is called CYTOKINESIS

2. The G1 stage is the first stage of interphase which occurs immediately after the cell divides i.e. after cytokinesis

3. The SYNTHESIS or S stage of interphase is the stage where the cell copies its DNA i.e. duplicates its genetic material (DNA).

4. MITOSIS is the process directly after interphase that consists of four stages viz; prophase, metaphase, anaphase, and telophase. This is where the nucleus divides and each cell contains a complete copy of the parental chromosomes.

5. The INTERPHASE is the main stage of mitosis where the cell grows, carries out normal functions, and duplicates its DNA.

6. The SECOND GAP PHASE or G2 stage takes place before mitosis and after synthesis of DNA (S phase).

1. The stage where the cell divides into 2 daughter cells with identical nuclei is called:

Cytokinesis

2. The stage of interphase which occurs immediately after the cell divides is known as:

3. The stage of interphase is where the cell copies the DNA is known as:

Synthesis

4. The process which directly occurs after interphase that consists of four stages. This is where the nucleus divides and each cell contains a complete copy of the parental chromosomes. This is called:

Mitosis

5.The main stage of mitosis where the cell grows, carries out normal functions, and duplicates its DNA is known as:

Interphase

6. The stage which takes place before mitosis and after synthesis of DNA is known as:

These are all the mitotic process where the cells are divided into interphase and mitosis and they further break down their process of cell division and differentiation.
