Which of the following cause sperm death on their journey to the egg?
Acidic environment
Cervical Folds
Female Immune Cells
Traveling to empty fallopian tube
Trapped in cilia of fallopian tube
Wind-like current caused by the cilia
Factor that HELP sperm get to the ovum
Factor that PREVENT sperm get to the ovum
Activation by chemicals in the female reproductive tract that change sperm membrane
Factor that HELP sperm get to the ovum
Factor that PREVENT sperm get to the ovum
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
Activation of digestive enzymes in this structure allow sperm to burrow through the corona radiata.
Acrosome
Flagella

Midpiece
How many sperm can fertilize a single egg?
1
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
Why can't multiple sperm fertilize an egg?
The egg produces chemicals that push other sperm away from the egg
The egg cell membrane changes preventing sperm from attaching to it
The zona pellucida hardens trapping sperm inside
The zona pellucida hardens so no more sperm can enter
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
Cilia pull zygote towards infundibulum
Cilia pull sperm towards infundibulum
