Where does the heat from your body comes from?

Answers

Answer 1

Answer: Every cell in the body produces heat as they burn up energy. Some organs will be on more than others, such as the brain, or muscles if you are exercising, therefore they get hotter. This needs to be spread around the body and this is done by the blood, which heats some organs and cools others.

Some chemotherapy drugs act by attaching themselves to the growing strand of a DNA molecule, thus preventing its replication. Cells on which phase of the cell cycle would be affected by this drug?

Answers

The answer is S phase.

If drugs prevent DNA replication which occurs in the S phase. That means that the S phase will be affected by these drugs.

is when the cell is on the S phase.

S-Phase is the part of cell cycle when the DNA is replicating, occurring between G1 and G2 phase

If the replication is somehow prevented, the drugs is most likely affecting the S-Phase

A father with type B blood and mother with type A blood have a child. Their child, while in a biology lab at school, tests her blood and discovers she has type O blood. Does she have any concerns about her parentage?A. Yes, because she should have type AB blood if they are her true biological parents.
B. No, because type O blood is possible if her parents both had genotypes AB.
C. No, because both of her parents could be heterozygous.
D. Yes, because both of her parents might be heterozygous.
E. No, because blood types A and B are codominant.

Answers

C. you can have an A or B blood type but also have recessive genes that could give an O if parent were heterozygous, like if the mother was A-i (i being recessive gene that could give 'O') and the father was B-i then if you do a punnett square then you can see that there's a 25% chance she has i-i or type O blood.

C. if the father was B, the mother was A, and the child had O, then the father had to be Bi and the mother had to be Ai
