Answer:

Explanation:

So lets go over facts of mieosis and mitosis:

Meiosis is sexual reproduction

Mitosis is asexual reproduction

Meiosis in animals is how they reproduce

Mitosis in animals is how they regenrate their cells

Mitosis copies the orgninal cell.

Meiosis mixes a male and female egg and sperm to form a zygote

Ok, knowing this. We can find our answer.

Since we know meiosis is sexual, and mitosis asexual, we can get rid of C.

We also know that meiosis is in animals, and so is mitosis, so we can get rid of A.

Finally we can get rid of D, since we know due to the male and female genetics(and through the swapping of chromesomes during prophase)that genetic variation occurs in meiosis, but since mitosis copies a single cell, it is not genetically varient.

<u>So the answer must be C, which states that Mitosis has genetically identical cells, while mieosis does not. </u>

Hope this helps! ;)

Answer:

Forms of fossils and there arrangement with layer of rock.

Explanation:

The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks.

The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.

Suppose a gene has two alleles, one of which is dominant over the other. An individual whose genotype is for the recessive allel

Trava [24]

Answer:

This question is incomplete, the options are:

A. Two copies of the allele that determines phenotype whenever the allele is present

B. Two copies of the allele whose effect is hidden unless the other allele is absent

C. One copy of the allele that determines phenotype when present and one copy of the other allele

D. One copy of each of two alleles that both contribute equally to determining phenotype

The answer is B.

Explanation:

According to Gregor Mendel, a Gene comes in two alternative forms called ALLELES. One allele called the DOMINANT ALLELE is capable of masking the phenotypic expression of the other called the RECESSIVE ALLELE. The dominant allele will always express itself whenever it is present. However, a recessive trait will only be expressed when two alleles for recessiveness occur in the gene.

An individual whose genotype is for the recessive allele will have two copies of the allele whose effect is hidden unless the other allele is absent. This means that in that particular gene, the two present alleles will be recessive alleles.

Answer:

Exergonic reaction

Explanation:

A chemical reaction which is associated with a release of energy and thus, is associated with a negative free energy change is said to be an exergonic reaction.

An exergonic reaction owing to the negative free energy change is a spontaneous reaction.

The energy that is released in the exergonic reaction is usually observed in the form of heat and light.

The energy is released due to the breaking of the chemical bonds.

Therefore, on burning of the firewood the bonds between the glucose molecules break up which leads to the release of energy in the form of heat and light and this is thus, an example of an exergonic reaction.
