The spem head or acrosome cap contains digestive enzymes such as hyaluronidase and acrosin which are used to lyse the outer wall of the ovum during fertilization
AcrosomeAcrosome
sperm head= contains DNA; also has acrosome (an enzyme to digest the membrane of the ovum) aids in egg penetration.
The sperm or the egg have 23 chromosomes. Humans have 46 chromosomes, so when these two combine they create a human zygote.
Enzyme Hyarulonidase is found mainly.It helps to degrade membranes around ovum
hyaluronidase
Probably because of the tail. It also depends on what kind of sperm are you looking at. The Head of the Human Sperm is 5µm and the tail is around 50µm. Human Red Blood Cell is 6-8µm. But if you will look at a bulls sperm its larger the human rbc and sperm
The nucleus of a sperm contains the DNA, seeing as a sperm is just another eukaryotic cell of the human body.
The enzyme in human saliva is Amylase.
human sperm cannot get a cow pregnant. The only species humans can get pregnant with their sperm is another human.
The tail of a sperm remains with the head until the sperm goes into the egg to fertilise it.
The sperm create an enzyme that eats away at the outer layer of the membrane of the egg allowing it to enter. The sperm then enters the egg and attaches its self.
Of course not. A female human can only get pregnant with a male human's sperm.
