What might happen if genetically modified deer mice with white fur where accidentally released into the wild population of mice? Explain what would happen to each population of mice, brown and
gray. Discuss how the addition of this genetic variation will affect the future generations of mice.

Answers

Answer:

They die.

Explanation:

If genetically modified deer mice with white fur were accidentally released into the wild population of mice, they will die and decrease in population because these genetically modified deer mice with white fur can't survive harsh conditions of the mice. Their colour also attract the predators at night so they catch these genetically modified deer mice with white fur and feed on them which automatically decrease its population.

Meiosis in males produces four identical sperm cells.
A. True

B. False

Answers

Answer:

B. False

Explanation:

Meiosis in males, not produces four identical sperm cells.

Meiosis is a type of cell division which involves the reduction in chromosomal content to half. The four daughter cells formed in meiosis are not identical. Thus, the given statement is false.

What is Meiosis?

Meiosis is a type of cell division in which the number of chromosomes reduces by half than that  present in the parent cell and produces four haploid gamete cells. This process is required to produce both male and female gametes- egg and sperm cells for sexual reproduction.

During the telophase II- last phase of meiosis, cell division is incomplete without another round of cytokinesis. Once the cytokinesis is complete there are four daughter cells, each with half a set of chromosomes (haploid) which are different due to the crossing over between chromatids.

The H substance is needed for the proper phenotypic expression of the A, B, and AB blood types in the ABO blood typing system in humans. Individuals who are recessive for the H substance (hh) will have a type O phenotype, even if they have the A and/or B alleles. Two individuals, each with type AB blood and heterozygous at the H locus have children. What is the probability they will have a child who is phenotypically type O?

Answers

Answer:

The correct answer is - 4/16.

Explanation:

In this question, it is stated that in ABO blood system the proper phenotypic expression of A, B, AB blood types needs H substance. If an individual has recessive for the H substance (hh) will have a type O phenotype.

The cross: ABHh and ABHh

gametes: two set of AH, BH, Ah, Bh

Punnett:

         AH         BH          Ah          Bh

AH    AAHH   ABHH     AAHh     ABHh

BH    ABHH   BBHH     ABHh     BBHh

Ah    AAHh    ABHh     AAhh      ABhh

Bh    ABHh    BBHh     ABhh      BBhh

As shown there is only 4 out of 16 offspring are recessive for H substance therefore, only 4/16 will have O blood group

what do you think if humans don't have stimuli?​

Answers

Then we won’t be able to know what’s going on our surroundings because most of our receptors in our body detect stimuli to come up with a response and if we as humans don’t detect stimuli then our brain won’t work, which will lead to nerve signals to stop working and that means our entire body won’t be functioning.

Answer:

I think it has to do with osmosis

Explanation:

Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.

When a cell is placed into distilled water, hypertonic solution takes place.

A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.
