In the heart, the valves are located between atria and ventricles and between ventricles and arteries (option D).
<h3>What are valves in the heart?</h3>
Valves are membranous partitions which permit the passage of the contents of a vessel or cavity in one direction, but stop or control the flow in the opposite direction.
Valves in the heart enforce a one-way blood flow through the heart and separate atria from ventricles, and ventricles from the large arteries that leave them.
The four valves in the heart and their location is as follows:
- tricuspid valve: located between the right atrium and the right ventricle
- pulmonary valve: located between the right ventricle and the pulmonary artery
- mitral valve: located between the left atrium and the left ventricle
- aortic valve: located between the left ventricle and the aorta.
The valves between the atria and ventricles are called atrioventricular valves or cuspid valves while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
Therefore, it can be said that the valves of the heart are located between atria and ventricles and between ventricles and arteries.

During meiosis but not during mitosis, which of the following is true? __.
A haploid gametes are produced that are identical in their allelic composition
B the cytoplasm divides
C chromosomes line up in the center of the cell during metaphase
D genetic variation among the daughter cells is increased
E two identical daughter cells are produced
Answer:
D. genetic variation among the daughter cells is increased
Explanation:
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. Meiosis occurs in germ cells, as a result; genetic variation among the daughter cells is increased. These cells (germ cells) are our sex cells – sperm in males, eggs in females.
In meiosis, the haploid gametes that are produced are not identical in their allelic composition.
In prophase 1, the chromosome pair up.
During metaphase, The chromosome pairs line up next to each other along the center (equator) of the cell.
Cystic Fibrosis is a genetic mutation
The vaccine used to prevent measles consists of live measles viruses. This type of vaccine is most likely <u>MMR vaccine</u>
MMR vaccine means Measles, Mumps, and Rubella vaccine.
