How many egg cell will meet sperm cell?
To create an embryo ONE egg and ONE sperm must meet. Males usually produce millions of sperm Females usually produce just a small number of eggs (depends on the animal) Once a sperm has fertilized the egg all the rest of the sperm are prevented from entering the newly created embryo.
Why are so many sperm released at a time?
The release of a large number of sperm in one ejaculate increases the chances of fertilizing an egg. Only one sperm can successfully fertilize an egg, so the more sperm released, the greater the likelihood of a successful fertilization.
Where will a sperm met an egg?
The sperm meets the egg inside the fallopian tube inside the woman's body. Once there is sperm inside the vagina, it must travel up through the cervix, up through the uterus, and into the fallopian tubes. Once in the fallopian tube where the egg has been release from the ovary, the sperm can meet up with the egg for fertilization.
Why must fertilisation take place in the fallopian tube and no in the uterus?
Fertilization takes place in the fallopian tube because that is where the egg and sperm meet. The fallopian tube provides the right environment for the sperm to travel and meet the egg, allowing for fertilization to occur. The uterus is where the fertilized egg implants and develops into a fetus.

Why must the male provide an excess of gametes while the female does not?
In most species, males produce a larger number of gametes (sperm) because they are smaller and more mobile compared to eggs. This higher number of sperm increases the chances of successful fertilization as sperm must travel to the egg and compete with other sperm for fertilization. Females, on the other hand, invest more energy in producing larger, nutrient-rich eggs that are less mobile and need protection, hence the lesser quantity.
Successful fertilization occurs in what tube?
isthmus boundary between the ampulla and isthmus
What are some challenges predator must meet?
Predators face challenges such as competition for food, adapting to changing environments, avoiding detection by prey, and dealing with potential injuries from hunting or defending territory. Additionally, they must also ensure successful reproduction and survival of offspring amidst these challenges.
Why are so many sperm necessary for fertilization to occur?
The large number of sperm released during ejaculation increases the chances of at least one sperm successfully fertilizing the egg. Sperm must navigate through the female reproductive tract, overcome various barriers, and compete with other sperm to reach the egg. By releasing millions of sperm, the likelihood of a successful fertilization event is significantly increased.
He came in you but you didn't get pregnant?
his sperm must not have reached the egg or the sperm is defuncted which means its useless
What layers that sperm must penetrate?
Sperm must penetrate through the cervical mucus, the cervix, the uterine cavity, and the fallopian tubes to reach the egg for fertilization.
