Answer:
D. Many amino acids are encoded by multiple codons. A gene mutation that encodes the same amino acid would have no observable effect on the cell or the organism
Explanation:
If gene mutation does not change code (gene still encodes for the same amino acid), the same protein with its function will be produced. This is called synonymous mutation.
Silent mutations might also occur when codon is altered to produce an amino acid with similar function as previous (e.g. leucine to isoleucine) so that the function of protein is not significantly changed.
In the absence of ADP, the conversion of NADH to NAD+ via the electron transport chain is prevented from happening.
<h3>What is glycolysis?</h3>
Glycolysis is the series of reactions by which glucose is broken down to pyruvate by the body.
NAD+ is a limiting factor in glycolysis. In the absence of ADP, the conversion of NADH to NAD+ via the electron transport chain is prevented from happening.
In conclusion, NAD+ is a limiting factor in glycolysis.

If we are performing a cross involving seed color in garden pea plants and if we cross true-breeding parents with green seeds and yellow seeds then the F1 offsprings will have yellow seeds.
- Since yellow seeds are dominant over the green seeds therefore in the first filial generation, all plants will have yellow seeds according to the Mendel's Law of Dominance.
- The Mendel's Law of Dominance states that if two parents from two different pure-breeding lines with contrasting traits of a character are crossed, then only one of the traits appear in the filial 1 generation and that trait is the dominant trait. For example, having yellow seeds is the dominant trait in this case.
Thus, if we are performing a cross involving seed color in garden pea plants and if we cross true-breeding parents with green seeds and yellow seeds then the F1 offsprings will have yellow seeds.

Answer:
When the heart contracts the body tissue receives its blood supply. When the heart relaxes the heart ventricles receive its blood supply.
Explanation:
The cardiac cycle consists of contraction and relaxation of the heart. The contraction is called systolic pressure and relaxation is called diastolic pressure.
The systole and diastole are mainly concerned with the ventricles, still, articular contraction and relaxation also occur. The blood from the auricles pushes into the ventricles. This is because of the auricular contraction. This initiates by SA node with a "Lub" sound.
The contraction means the pressure of the blood is more in the auricle and the mitral valve and tricuspid valves open. The blood enters the ventricles. Then the pressure of auricles becomes less.
Now the ventricles are filled with blood and the pressure of the blood is more in the ventricles. This is called ventricular systole, and it leads to open the semilunar valves.
The blood is ejected out by aorta and supply to different parts of the body. After the blood ejection, the ventricles are in the relax stage, which is called the diastolic stage.
One systolic pressure is followed by one diastolic phase. Due to systolic pressure/ contraction, the blood pumps out of the heart.
