Humans are more closely related to hogs than hogs are to guinea pigs.

Explanation:

The difference in the amino acid sequence of a protein is used to know the  relation between organism i.e. how closely they are related.

It is known that proteins are the result of DNA sequence ie genes of the organism.

The gene or protein is compared between organisms to understand the evolutionary evidence and similarities between them.

The less is the difference the more is the two organisms closely related as in the case of hog and human which have only 1 amino acid difference in their insulin enzyme. While guinea pig is having  a difference of 17 amino acids so it is expected to be distantly related.

These relations helps the scientist to resolve the issues of crisis say insulin. They zero out the possibility of extracting the enzyme genes of possible organism and increase the yield.

Therefore, Wendy's genotype must be bb and her father's must be Bb. 

The genotype is your total heritable hereditary character; it is your one of a kind genome that would be uncovered by individual genome sequencing. In any case, the word genotype can likewise allude just to a specific quality or set of qualities conveyed by a person. For instance, in the event that you convey a change that is connected to diabetes, you may allude to your genotype just as for this transformation without thought of the various quality variations that you may convey.

The rapid depolarization phase of the action potentials of myocardial contractile cells is due to which ion(s)? The rapid depola
fgiga [73]

Answer:

Na+ only

Explanation:

Depolarisation of membrane refers to the change in the resting membrane potential of the membrane of a cell which is usually -70mv to a more positive value.

This value changes when the positive ions move inside the cell which increases the positive charge inside the cell.

In the myocardial cell, the sodium ions move inside the cell which changes the potential towards the more positive side as a result of which the signals for contraction arises.

Thus, Na+ only is correct.

andriy [413]
<span>If Noam chooses a filter, it might be more effective than a screen. After using it for a while, though, he will have to replace it, which could be expensive. A screen might be less effective, but it can be cleaned instead of replaced.</span>
