I just took the test and the answer is actually D) Because Solar cells transform radiant energy from the sun into electrical energy. It is more expensive, however, than the transformation of thermal energy into electrical energy by combustion. Therefore, solar cells would be more practical if they were LESS EXPENSIVE<span><span>. </span></span>

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.

How do the daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in G 1 of the cell cy
Vikentia [17]

Answer:

b. The daughter cells have the same number of chromosomes and the same amount of DNA.

Explanation:

Mitosis is the cell division that maintains the DNA amount and chromosome number in daughter cells. This is due to the fact that each mitosis is preceded by one round of DNA replication in S phase.

For example, if the parent cell had 2n DNA in 46 chromosomes, the daughter cells at the end of mitosis and cytokinesis would also have 2n DNA in 46 chromosomes.
