341378 What is true in the process of fertilisation?

1 Only one sperm reaches the egg and enters it.
2 The entry of sperm activates the egg for completing meiosis.
3 Two haploid nuclei fuse and immediately divide to produce two nuclei which are again haploid.
4 Only the acrosome of the sperm enters the egg.

341380 Select the incorrect statement about external fertilization

1 Organisms showing external fertilization produce a large number of male gametes only.
2 External fertilization is very uncertain and requires synchrony between release of male and female gametes.
3 It replaced by internal fertilization in higher organisms as it wastes energy and requires external medium like water.
4 It occurs in most of the fishes and amphibians.
