Mitosis is when a DNA error, aka mutation, occurs in a body cell. When cells divide, it needs a copy of the DNA. During DNA replication, that error can cause the instructions for building proteins to differ. The change can not affect offspring. Meiosis is the same situation, but in sex cells. This can be transferred to offspring.

The statement that "A clustering appointment type is when patients with similar problems are booked consecutively on the same day" is true. Clustering is type of appointmnet scheduling. In this type of scheduling patients with similar problems are booked consecutively. A block of time is set aside for particular types of cases.
Channels, when they open, just allow the molecule to pass through. With a pump, it requires energy, and will move it in a certain direction. They move rapidly into the cell via protein molecules.

Glad I could help you!
Answer:
70 ml/beat.
Explanation:
Stroke volume may be defined as the volume of the blood that are pumped by the left ventricle in one contraction. The blood output can also be determined by knowing the stroke volume.
The stroke volume can be calculated by the formula as follows:
Stroke volume = End diastolic volume - End systolic volume
Here, end diastolic volume = 120 and end systolic volume = 50.
Stroke volume = 120 - 50
Stroke volume = 70 ml/ beat.
Thus, the answer is 70 ml/ beat.
