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.

Answer:
1. Light.
2. Atmospheric.
3. Energy from e.
4. Water molecule.
5. Oxygen.
6. Energy, hydrogen.
A.
TUC GCT
B.
ATG CGA
C.
UAC GCU
D.
TAC GCT
The complementary DNA strand for the given DNA strand "ATG CGA" would be "TAC GCT". Therefore, option (D) is correct.
When DNA is transcribed to mRNA, it follows the base-pairing rules where Adenine (A) pairs with Uracil (U), and Cytosine (C) pairs with Guanine (G).
However, in the question, we are asked about the complementary DNA strand, where Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G). Therefore, to find the complementary DNA strand, we need to replace each base with its complementary base.
