When blood is flowing through a vena cava, which main blood vessel will it flow through next?

Biology
1 answer:
prohojiy [21]3 years ago
6 0

Answer:

C.

Explanation:

When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts.

As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.

2. A certain recessive, lethal gene is carried on the X chromosome. (Lethal genes are those that result in death.) A man marries
son4ous [18]
The surviving children would be 66.7% female and 33.3% male. Of the female children, 50% would be expected to be carriers of this gene (like their mother)
| Xg | X
—————-
X | XXg | XX
—————-
Y | XgY | XY

Pretty ugly, but the best punnet square I can do without a link. The offspring with the “g” are those that carry the lethal gene. The male child that carries it will die, but since it is recessive, the female child will live but will be a carrier for this gene. I hope this helps.
