How many sperm cell are needed for fertilization?
Only one sperm is required to fertilize an egg. One is both necessary and sufficient in order for an egg to be fertilized. But in order to be confident that one will make it, you need a certain minimum sperm count.
When an egg and a sperm join during fertilization they form the first cell of a new organism and this cell divides into many cells to form what?
to form a zygote !!
Adaptations in land animals help ensure internal fertilization?
There are many reasons why land animals use internal fertilization. One very important reasons land animals use internal fertilization is protection.
How many hours must sexual intercourse occur for a sperm cell to fertilize an ovum?
IT takes about 2 hours for a healthy sperm to reach the fallopian tube of the uterus.
Is human fertilisation internal or external?
Human fertilization is internal. In humans, fertilization occurs internally within the female reproductive system. During sexual intercourse, sperm is ejaculated into the vagina, and the sperm cells travel through the cervix, uterus, and into the fallopian tubes. It is within the fallopian tubes that fertilization typically occurs when a sperm cell successfully penetrates and fertilizes an egg. After fertilization, the resulting zygote implants into the lining of the uterus, where it develops into an embryo.
Why is necessary to release so many sperm at a time?
to ensure the fertilization of the egg with the mostcompatible sperm
What happened doing fertilize?
If your question is what happens during fertilization? the answer varies. If your are speaking about sexual reproduction then fertilization occurs when the sperm and egg combine. Basically the first sperm to get to the egg keeps it. The egg hardens to keep excess sperm from entering. (of course some errors can occur which will lead to defects, twins, triplets, etc.) There are many other phases to the reproduction process but fertilization is basically when the egg and sperm combine.
Why so many sperms are needed for fertilization to occur?

What are the similarities of internal external fertilization?
Internal fertilization takes place inside the body of the female. It is necessary for animals which live on land (terrestrial animals) and is retained by aquatic animals descended form terrestrial ancestors eg whales and dolphins. External fertilization takes place outside the body of the female. It usually takes place in water, usually the environment in which the animal lives eg fish and amphibians. This is because eggs and sperm would dry out and die if they are not kept wet. Internal fertilization is more certain than external fertilization so fewer eggs need to be produced. After internal fertilization eggs can be protected and fed while developing inside the mother's body. After external fertilization the eggs are potentially exposed to predators and so must either be produced in very large numbers or protected by the parents or both.
How many hours will sperm live in vagina if fertilization doesnot occurs?
48-72 hours
