Answer:
The blood pressure is increased to pump more blood to distribute more oxygen to the muscles
Explanation:
When we do activities that demand heavy exercise like running, our body needs more oxygen to carry out property the exercise. Oxygen is transported to muscles by the circulatory system (principally blood), our heart starts to pump faster the blood ( increase the blood pressure) to distribute the oxygen between muscles, consequently, we start to breathe faster to increase the oxygen intake.
I think this is an theory changing because a new scientific method was developed. They used what Mendel had learned to test the hypothesis themselves and discovered that he was right.
Answer:
4 1/4
Explanation:
17/4 = 4/4 + 4/4 + 4/4 + 4/4 + 1/4
4 + 4 = 8
4 + 4 = 8
8+8=16 = 16/4
16/4 + the 1/4 remaining in the equation = 17/4
so 4/4 + 4/4 + 4/4 + 4/4 = 4
4 + 1/4 = 4 1/4
sorry if you couldnt follow along. I am not good at explaining things but the answer is 4 1/4

Answer:
The effect might be due to the gene expression.
Explanation:
The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.
