Answer:
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
Explanation:
the question is incomplete, but I annex the options and their explanation
When you compress the heart in this demo, why does the water leave the artery?
A It's like squeezing a sponge
B The arterial valve draws water from the ventricle.
C The atrioventricular valve has parachute-shaped fins to prevent water from escaping from the top.
D The atrioventricular valve works as a rigid door to prevent water from escaping from the top.
the atrioventricular valve during the contraction process closes at the top, thus avoiding the leakage of the liquid and leaving the artery that opens due to the force exerted by the volume and force of the ventricle.
Answer:
Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
"Mathew Meselson and Franklin Stahl performed classic experiments that supported semiconservative nature of DNA replication in 1985."
A band of hybrid 14N and 15N DNA was produced as a result of the DNA's initial duplication in a 14N medium. The conservative replication mode was so abandoned. "Based on their observations and experimental results, Meselson and Stahl concluded that DNA molecules can replicate semi-conservatively."
One original DNA serves as a template for the production of two DNA copies during conservative replication. One of these two is made entirely of fresh DNA, while the other is made of strands from old DNA. In semiconservative replication, the parent strand is used to make two copies of the DNA, each of which contains one original strand and the other new strand.

Answer:
Ur answer
Explanation:
If the bacteria grows for six hours each bacterium will divide <em>3 times/hour * 6 hours = 18 times.</em>
Every time the bacteria reproduce the number doubles.
