It has a tail that allows it to propel itself. Also, contractions of the uterus and Fallopian tubes help.
The fact that only one sperm can fertilize an egg. After the sperm enters the cytoplasm of the oocyte, the cortical reaction takes place, preventing other sperm from fertilizing the same egg
A sperm fused with an egg
To get to the egg the sperm has to first go through sexual intercourse and then the sperm travels in a liquid till it reaches the fallopian tube where the egg is to get into the egg the sperm uses its tail. (only a brief way)
Fertilization occurs when a sperm and egg unite.
Yes, if the sperm is in the egg, the egg is fertilized.
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.
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)
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
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.
The fact that only one sperm can fertilize an egg. After the sperm enters the cytoplasm of the oocyte, the cortical reaction takes place, preventing other sperm from fertilizing the same egg

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.
To get to the egg the sperm has to first go through sexual intercourse and then the sperm travels in a liquid till it reaches the fallopian tube where the egg is to get into the egg the sperm uses its tail. (only a brief way)
The size of egg is larger than sperm because the the sperm enters inside the egg and egg has to accommodate the sperm. And egg contains fats and nutrients in order to feed zygote in case of pregnancy.
