(200 words)Which mechanism prevents an ovum from being fertilized by multiple sperm cells? A. Once a sperm penetrates the jelly-like coating of the egg, no other sperm cell can penetrate the coating. B. When a sperm fuses with the plasma membrane of the egg, depolarization of the membrane occurs. C. The egg can survive in the Fallopian tube for 24 hours s it does not have mitochondria to produce energy. D. When more than a single sperm cell fuses with the plasma membrane, multiple zygotes can form, leading to the twin or triplets.evel Basic Features of Reproduction Which of the following features does not differentiate asexual reproduction from sexual reproduction? Asexual reproduction involves a single parent but it is not the case in sexual reproduction. Sexual reproduction does not involve gamete formation but asexual reproduction does.
