Answer:
In mitosis, the daughter cells have the same number of chromosomes as the parent cell. But, in while meiosis, the daughter cells have half the number of chromosomes as the parent.
The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.

Answer:
Cardiac output = 20 L/min
Explanation:
The cardiac output of a person refers to the volume of blood the heart pumps in a minute. The normal range for cardiac output is about 4 to 8 L/min. However, this can vary depending on the metabolic needs of the individual at any instant of time, for example, it is higher when exercising than when resting.
Cardiac output is calculated from the product of the stroke volume in liters/min and the heart rate in beats/min
Cardiac output = stroke volume * heart rate
For the individual who is running; stroke volume = 100 mL/beat or 0.1 L/beat
heart rate = 200 beats/min
Cardiac output =0.1 L/beat * 200 beats/min
Cardiac output = 20 L/min
I would say an island with a lake, mountain, and rivers in the tropics, because that would generally have the most diverse population
Answer:
Explanation:
The Genotype of the woman is XCbXN
The man XNY
Since the allele for the color blindness is carried on one of the X -chromosomes of the carrier mother, then the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal allele from the mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal X allele from the father.
Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes
1. XNY vs XCbXN.Then the one of the boys will be colorblind and the one of girls will be carriers. XNXCb, XNXN, XCbY,XNY 50 %
2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle
Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).
The proportions that will be the females since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls take the defective allele from the mothers and take normal from the father,they will all be carriers,since the X of the father is normal.
They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.
