When a person has a few drinks containing alcohol, they often feel the need to urinate. This response suggests interplay between
belka [17]

Answer: The way alcohol and ADH interact is:

a. Alcohol inhibits the binding of ADH to receptors in the brain, so individuals "feel" the need to urinate.

Explanation: The alcohol make the nerve cells less excited and it reduces or slow down the brain activities, which would make sure that the ADH is not secreted to decrease the release of urine. Hereby increasing the number of times the person would urinate.

Lubov Fominskaja [6]

Answer:

During mitosis, the nucleus divides. Mitosis is followed by cytokinesis, when the cytoplasm divides, resulting in two cells. After cytokinesis, cell division is complete. Scientists say that one parent cell, or the dividing cell, forms two genetically identical daughter cells, or the cells that divide from the parent cell. The term "genetically identical" means that each cell has an identical set of DNA, and this DNA is also identical to that of the parent cell. If the cell cycle is not carefully controlled, it can cause a disease called cancer, which causes cell division to happen too fast. A tumor can result from this kind of growth.

During mitosis, the two sister chromatids must be split apart. Each resulting chromosome is made of 1/2 of the "X". Through this process, each daughter cell receives one copy of each chromosome. Mitosis is divided into four phases:

Prophase: The chromosomes "condense," or become so tightly wound that you can see them under a microscope. The wall around the nucleus, called the nuclear envelope, disappears. Spindles also form and attach to chromosomes to help them move.

Metaphase: The chromosomes line up in the center of the cell. The chromosomes line up in a row, one on top of the next.

Anaphase: The two sister chromatids of each chromosome separate, resulting in two sets of identical chromosomes.

Telophase: The spindle dissolves and nuclear envelopes form around the chromosomes in both cells.

In the family tree below, people with the recessive trait of attached earlobes are shaded gray.
maks197457 [2]
The first thing that could help you is that squares are male and circles are female, which means that C and D are incorrect.
Now, <span>the sister has attached earlobes, so both parents must have the recessive allele along with the dominant, which means that the child has both recessive and dominant as well. This means that the correct answer is A. </span><span>It is a male with at least one dominant allele.</span>
