A water that has a pH (potential hydrogen) of 3.2 would be the most acidic. That is because 7.0 is the neutral phase or measurement of a substance or a solution. Anything that is below 7.0 is acidic, the lower it is the more it becomes acidic. Anything that is higher than 7.0 is basic (alkaline) opposite with the acid, the higher it gets the more it is a basic.
The phenotype ratio would be 25% each for widow's peak and freckles, widow's peak without freckles, straight hairline with freckles, and straight hairline without freckles.
<h3>Dihybrid crossing</h3>
Genotype of the heterozygous parent: HhFf
Genotype of the other parent = hhff
Crossing the two parents:
HhFf = 1/4 = Widow's peak, freckles
Hhff = 1/4 = Widow's peak, no freckles
hhFf = 1/4 = straight hairline, freckles
hhff = 1/4 = straight hairline, no freckles.

Answer:
See the answer below
Explanation:
First, the image tells that chromosomes are made up of genes or that genes are located on chromosomes. It further showed that genes are translated as proteins in the cell and this protein respectively control the expression of traits.
Secondly, it also showed that during sexual reproduction, the offspring produced usually have the same proteins as the parent and therefore have exactly the same traits as the parent. Only one parent is needed for asexual reproduction.
<u>However, two parents are needed for sexual reproduction where each parent donate chromosomes containing gene to the genome of their offpsring. The mixture of genes ensures that the offspring look different from the parent.</u>
<em>The image further showed that asexual reproduction does not lead to any variation while sexual reproduction leads to variation of the offpsring from their parents.</em>
Selective breeding is something only ascended organisms can adapt to. Us humans use selective breeding. Animals without complex language, artistic capabilities, etc, are unable to adapt to C.
D is your answer.
