It has a tail that allows it to propel itself. Also, contractions of the uterus and Fallopian tubes help.
No, generally only one sperm is able to fertilize an egg. Once a sperm penetrates the egg, the egg's protective layer prevents other sperm from entering. This ensures that only one set of genetic material combines with the egg to form a new individual.
Yes, it is possible for 2 sperm to reach the egg, however only one will fertilize the egg. It isn't uncommon for more than 2 to reach the egg, depending how are along the egg is down the falopian tube. And how much sperm was ejaculated.
Fertilization occurs when a sperm and egg unite.
In humans, only one sperm can fertilize an egg to form a zygote. If more than one sperm were able to fertilize an egg, it would result in an abnormal number of chromosomes in the zygote, leading to developmental issues and likely miscarriage. This phenomenon is known as polyspermy and is usually prevented by mechanisms in the egg that block additional sperm from entering once one has already fertilized it.
Yes, sperm can enter the uterus without fertilizing the egg. Just because a woman is fertile doesn't mean she will fall pregnant, there are a LOT of things that can go wrong to prevent pregnancy such as poor sperm quality or there not being enough sperm reaching the egg to fertilize it.
Puberty.
Puberty.
The shape of the sperm is a component needed in order for the sperm to penetrate the layers surrounding the egg. Each sperm needs a head, tail, and mid-piece.

The Ovalry Releases an egg and and the sperm travels through the fallopian tube to meet the egg.When They Meet they form A Zygote then it develops into an Infant
no it does not it says in the information that it keeps the sperm from reaching the egg (it kills the sperm not the egg)
after an egg is penetrated by a sperm, the egg and sperm nuclei fuse to form a single nucleus. within 2- 5 minutes after sperm penetration, a fertilization membrane forms beneath the jell coat to prevent the entry of additional sperm.

It enables the sperm to swim towards the egg so that it can fertilise it. ------------------------------------- Sperm have tails because they need to be able to swim to the egg. They wiggle their tail which helps them to move along and make it to their destination. ----------------------------------------- Tail with the Sperm is just like tail with the fish. so tail makes the sperm to move along the path. it works like a flagella in bacteria. ------------------------------------------------ it is to aid the sperm to swim from the point of ejaculation to the egg. Once it enters the egg the tail breaks off. -------------------------------------------------- The sperm cell has a long tail in order to propel the head of the sperm, which carries all the DNA information, towards the egg. It is simply to help the sperm reach the egg. Once the sperm reaches the egg, the tail is naturally absorbed through the body's tissues. ------------------------------------------------------
sperm and egg. the sperm FERTILIZES the egg.
