Answer 1

3a. An animal that uses internal fertilization is the chicken.

3b. Two reasons why the females of this animal produce only a few egg cells are:
1. Energy conservation: Producing a large number of eggs requires a significant amount of energy, which may not be sustainable for the female.
2. High survival rate: With fewer eggs, the chances of survival for each individual egg increase, ensuring that at least some offspring survive to adulthood.

4. I would expect mouthbrooder females to produce fewer eggs because:
- Increased parental care: By investing more time and resources in caring for each individual egg, mouthbrooder females can ensure that a higher percentage of their offspring survive. This strategy is advantageous in environments where the risk of predation or other threats is high.
- Limited reproductive capacity: The act of mouthbrooding requires a significant amount of energy and resources. By producing fewer eggs, mouthbrooder females can allocate their resources more effectively to ensure the successful development and survival of their offspring.
