Answer:
b
Explanation:
tricuspid valve
mitral valve
The mitral valve prevents a backflow of blood into the left atrium. It closes when the heart contracts, preventing blood from flowing back. Other valves like the aortic and tricuspid have different functions.
The mitral valve, also known as the bicuspid valve, is the valve that prevents a backflow of blood into the left atrium. This valve is located between the left atrium and the left ventricle. When the heart contracts, the mitral valve closes, preventing blood from flowing back into the atrium. The other valves listed, the aortic valve and the tricuspid valve, have different functions. The aortic valve controls blood flow from the left ventricle into the aorta, and the tricuspid valve prevents backflow of blood into the right atrium.

Dichotomous keys are represented in two ways including either as descriptive representation in which a series of paired statements arraged in a numbered sequence or as a branching flowchart (diagrammatic representation).
Hence, the correct option is c.
Answer:
Each is a series of statements
Explanation:
If you have seen dichotomous keys you see that there are tables and flo charts. Notice each answer choice says "Each" but there are many different kinds. Dichotomous keys are definitely not mathematical formulas. SO you can infer it is a series of statements. Also I took the test
