C.
Explanation:
Human reproduction is any form of sexual reproduction that results in fertilisation by humans. It normally includes a man and a woman having sexual intercourse. During sexual intercourse, the contact between male and female reproductive systems leads to the woman's ovum being fertilised by the man's sperm.
In human fertilization, a hapoloid ovum is released that fuses with a haploid sperm and produces a single 2n diploid cell called the zygote.
Hence, the correct option is C.

The ice age was a period during which the average temperatures on the globe dropped significantly, in a short geological time. We know that large animals have a big volume to surface ratio so that they do not have as many problems with regulating heat in cold conditions as smaller animals; they have proportionally less surface, hence there are fewer ways for them to lose heat. Thus, large animals are well-suited for the ice age. A major factor in the extinction of such animals is a hotter climate since this makes heat regulation in the animal very hard (the animal cannot cool itself). Thus, given the findings, one can infer periods of rising temperatures in LA by the fossil record.
