What else can I help you with?
Why are there more egg and sperm cells produced during external fertilization than during internal fertilization?
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
Which gender's sperm, male or female, moves faster during fertilization?
Male sperm typically moves faster during fertilization compared to female sperm.
What is the chemical released by sperm during fertilization?
The chemical released by sperm during fertilization is an enzyme called acrosin. Acrosin helps the sperm penetrate the protective layer around the egg, facilitating fertilization.
What unites during fertilization?
During fertilization the sperm unites with the egg. This typically occurs in the fallopian tube.
Does sperm always reach the egg during fertilization?
No, sperm does not always reach the egg during fertilization. Only one sperm typically fertilizes the egg, while the rest are blocked from entering.
What helps sperm reach the egg during fertilization?
During fertilization, sperm reach the egg with the help of their tail movement and enzymes that break down the egg's outer layer.
What process by which the egg cell and sperm cell unite during sexual reproduction?
No. Fertilization is the joining of an egg and sperm.
What is the uniting of an ovum and sperm cell?
The uniting of an egg and sperm cell is called unification
Is sperm considered as antigen at the time of fertilization?
No, sperm is not considered an antigen at the time of fertilization. Antigens are substances that the immune system recognizes as foreign and can trigger an immune response. Sperm is a normal component of reproduction and does not elicit an immune response during fertilization.
What happens to the egg and the sperm during fertilization?
The nuclei of the egg and sperm cells fuse to form the fertilized egg.
What do sperm contribute during fertilization?
Sperm contribute genetic material to fertilization, specifically the father's DNA, which combines with the mother's DNA to create a unique genetic blueprint for the offspring. Additionally, sperm provide the necessary enzymes to penetrate the egg and trigger the process of fertilization.
What prevents multiple sperm from fertilizing one egg during the process of fertilization?
During fertilization, the egg releases chemicals that prevent other sperm from entering once one sperm has successfully fertilized it. This process is called the zona reaction, which helps ensure that only one sperm can fertilize the egg.
