The Mitral valve which is also known as left atrioventricular prevents blood movement from left ventricle to left atrium.
Explanation:
- Human heart is four chambered.
- Two of these are receiving chambers known as atria and the other two are distributing chamber known as Ventricles.
- Atria are superior chambers and ventricles are inferior chambers.
- The heart has four valves broadly grouped as Atrioventricular valves and Semi lunar valves.
- Atrioventricular valves allows flow of blood from atria to ventricle. These are tricuspid valve and bicuspid valve.
- Semi-lunar valves allow blood to pass out of the heart. These include the pulmonary and aortic valves.
- The pulmonary valve allows blood to flow from right ventricle to the heart while aortic valve allows blood to flow from left ventricle to the Aorta.
- The Tricuspid valve located between the right atrium and right ventricle allows blood to flow from right atrium to the right ventricle.
- The Bicuspid valve ( Mitral valve) located between the left atrium and left ventricle allows the blood flow from left atria to left ventricle.
- Valves maintain the unidirectional flow of blood and thus prevent its back flow.

Heredity

Im not sure how to explain it lol but thats the answer
Answer:
Animal life cycles have meiosis followed immediately by gametogenesis. Gametes are produced directly by meiosis. Male gametes are sperm. Female gametes are eggs or ova.
The plant life cycle has mitosis occurring in spores, produced by meiosis, that germinate into the gametophyte phase. Gametophyte size ranges from three cells (in pollen) to several million (in a "lower plant" such as moss). Alternation of

(Spore)
Microbes are classified into various groups on the basis of their characteristics to make the study easier.
Generally speaking, there are 2 major forces that cause genetic divergence in the majority of populations and systems.
And those are;
Natural Selection
and
Mutation
Natural selection causes a divergence due to the fact that organisms with " "better", more advantageous traits dependent on their environment, survive and reproduce, while the others have the lesser chance. (This causes traits in the population to change over time.)
Mutilation/Mutations, on the other hand, is a change in the genetic material of an organism-specifically when DNA is copied incorrectly.
This changes a portion of the genetic makeup of an organism, therefore changing the organism, and changing its future generations of offspring (when made...etc)
