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.
The reason to maybe explain why crops in the Arctic grow larger than normal during the summer months is because of warmth. The sun may be making it warmer down <span>there at that time.</span>
<span>Most organisms can move from their home territory to new sites in a process called MIGRATION. A lot of animals do this like birds and fish, because they need to find warmer temperatures where they can breed and survive. When animals do not have this capacity, they won't be able to adapt within their given environment and mortality rates might go up. </span>
Fungi are either saprophytes or parasites
