Systolic and diastolic blood pressures are affected differently by exercise? what could account for the difference?

Biology

kondaur [170]3 years ago

Your heart has to work hard to pump more blood during exercise for each contraction, accounting for the increase in the systolic blood pressure. Diastolic pressure tends to not change at all or change slightly. The reason for this is that since the blood flow is increased during exercise, our arteries dilate, making the diastolic pressure stay the <span>same, or decrease slightly.</span>

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
swat32

The correct answer is optionD 134/200.

The frequency of the dominant allele can be calculated by the summation of the frequency of the homozygous individual frequency that has  dominant allele  and half of the heterozygous individuals, as half of the heterozygotes have dominant allele.

The frequency is no of individual of desired trait divided by total number of individual.

The calculation is shown below:frequency of dominant allele=frequency of dominant individual+\frac{1}{2} frequency of heterozygotes\\frequency of dominant allele=\frac{50}{100} +\frac{1}{2} (\frac{34}{100} )\\frequency of dominant allele=\frac{50}{100} +\frac{34}{200} \\frequency of dominant allele=\frac{2(50)+34}{200}\\ frequency of dominant allele=\frac{134}{200}

EastWind [94]
<h2>Answer:</h2>

Based on the information given we can not say pea aphid as an autotroph. Because pea aphid ability to produce ATP in the presence of sun is due to the light-capturing pigment that it gains from the genes transferred from fungi.

As pea aphid do not have any chloroplast and it cannot fix carbon so it is not a true autotroph. We can say it false autotroph because it can produce ATP in the presence of sunlight and can show increased production of ATP at the higher level of pigment.
