Biology

Xelga [282]3 years ago
5 0

Based on DNA sequences, it is believed that changes in nucleotide sequence between two species are equivalent to the time that has elapsed since the two species diverged from their common ancestor. Gene sequencing is being used in addition to morphology to determine evolutionary relationships between organism. Homologous sequences show greater evolutionary relationship

quizlet i]n the heart, valves are located in the heart, valves are located just between the ventricles and the arteries. just be
ser-zykov [4K]

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:

  1. tricuspid valve: located between the right atrium and the right ventricle
  2. pulmonary valve: located between the right ventricle and the pulmonary artery
  3. mitral valve: located between the left atrium and the left ventricle
  4. 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.

Why do traits increase within a population over time
Olegator [25]
Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
