The tip of the little swimmer contains a kind of fluid that is able to break down the shell of the egg. the fluid will change the surface of the egg enough so it can break through. Using a metaphor, it's like when you pour acid on a wooden table and it eats right through. It's the same principle (only less harsh and brutal as I just made it sound)
What else can I help you with?
When do humans need meiosis?
Meiosis produce haploid cells.So meiosis is used to produce sperms and ova.
How many sperms unite with the egg whath do call this union?
Only one sperm will enter the egg. It is known as fertilisation.
In what ways are sperm and ova similar?
both ova and sperms are reproductive cells or gametes. they both are haploid because their chromosome number is 1n . they both fuse to form zygote which is diploid and has 2n chromosome number
Which part of the female part produces sperms?
A female plant part does not produce sperms. It produces egg. The sperms are produced by the part of a male plant.
Ova are found inside this?
Ova are found inside the ovaries of female animals, including humans. The ovaries are responsible for producing and releasing mature ova, or eggs, which are necessary for reproduction.
what cells of a human are diploid and which are haploid?
Exept sperms and ova all are diploid.
How are sperm cells and ova different?
A woman is born with so many ova, or eggs, at the time of her birth. She does not produce any more eggs through her lifetime but instead, looses one or more each month through menstruation A woman cannot use them after menopause. The supply of sperm is endless. A man produces more sperm as necessary and can produce them until he dies.
Which type of twin are created when two ova are fertilized by two sperms?
dizygotic or non-identical twins
When do humans need meiosis?
Meiosis produce haploid cells.So meiosis is used to produce sperms and ova.
How do the products of meiosis in men compared to meiosis in women?
the products of meiosis i. e. sperms, in men are several times more than the ova, in women
When does human begins its life?
The life of an human begins when the sex cells or gametes unite.Sex cells are the male sperms and the female ova.During copulation the sperms travels to meet the ova in order to fertilise with it.When they fertilise a zygote is formed which is single cell.
What happens if two sperms enter the egg during fertilization?
When two sperms enter the egg during fertilization, it results in an abnormal number of chromosomes in the embryo, leading to a condition called triploidy. This usually results in a nonviable pregnancy and early miscarriage.
Is it fine if sperms enter your belly button?
If the sperm enter your belly button it is fine as you are not going to get pregnant that way. just wash it well.
What is the role of sperms?
The role of sperm is to donate the half genetic material to make a complete diploid individual. It has a tail which help it to swim or to reach to the ova- the female cell. In the head portion there are certain enzymes which can digest the membrane of ova so it can do its job.
There are possibility that you may be pregnant when sperms enter while in period?
You can't, wrong time of the cycle
The vagina is the birth canal from the uterus to the vulva which?
allows blood flow to pass and sperms to enter
What Kind of cells can mitosis not make?
Mitosis can't produce gametes as sperms and ova, which have 23 chromosomes. It only produces somatic cells which are used in the rest of the body that contain 46 chromosomes.
