F=ma
m=40 kg
a= unknown
f= 400 N
rearrange equation to f/m=a
so (400)/(40) = 10 m/s/s

Answer:
Aids in preventing polyspermy.
Explanation:
Polyspermy is a process that involves multiple fertilization of an egg by multiple sperm, which leads to the embryo inheriting multiple centrioles from the parents. Polyspermy is often considered lethal, and there are several mechanisms in most animals that prevents multiple fertilization of eggs. One of such mechanisms is the possession of a micropyle by zebrafisg eggs which limits the chances of multiple fertilization, as only one sperm is able to pass through the micropyle at a time. This micropyle most likely aids in preventing polyspermy.
