Question

4 do animals that fertilize their eggs internally produce more or less young than animals that fertilize their eggs externally?
5 which eggs are more likely to be fertilized, those that are fertilized internally or those fertilized externally?

Explanation:

1. External fertilizers release large numbers of gametes into the environment, where many are lost, so they produce far more offspring to compensate for low survival rates. Internal fertilizers invest more in each offspring, so they produce fewer.
2. Internal fertilization involves direct transfer of sperm to the female reproductive tract, which reduces gamete loss and increases the chance of sperm-egg contact, unlike external fertilization where gametes are exposed to environmental factors that reduce fertilization odds.

Answer:

1. Animals that fertilize eggs externally produce more young than those with internal fertilization.
2. Eggs fertilized internally are more likely to be fertilized than those fertilized externally.
