The female reproductive tract releases chemicals in the fallopian tube that change the sperm membrane. How do sperm change as a result?
They become hyperactive and swim faster and harder towards the end
They become sluggish and swim slower and softer towards the end
They die and lose the ability to swim towards the egg
They become paralyzed and lose the ability to swim towards the egg

2
Unlimited
Varies
What will happen to the first sperm that comes into contact with the egg membrane?
Their membranes will fuse and the sperm is pulled inside the egg
Their sperm membrane will become glued to the outside of the egg and remain there
Their sperm's DNA will be sucked inside the cell while the rest of the sperm will fall off of the egg's surface
Varies
After the sperm has fused with the egg and entered, what events take place?
The pronuleus of the male and female fuse completing the process of fertilization
The pronuleus of the male and female separate completing the process of fertilization
