Living Environment Regents Practice Test

What is one advantage for an offspring to develop internally?

1. Increased genetic diversity

2. Richer genetic material

3. More protection leading to higher survival rates

4. Access to a larger food supply

The correct answer is: More protection leading to higher survival rates

The advantage of internal development, leading to more protection for the offspring, is crucial for survival. When an embryo develops inside the parent, it is shielded from environmental hazards and predators, which significantly enhances its chance of surviving until birth. In contrast, external development often exposes eggs or young organisms to temperature fluctuations, desiccation, or predation. By nurturing the offspring internally, parents can provide a stable environment that supports growth and development, increasing the probability that the offspring will survive and reach maturity. Other options do not capture this critical benefit of internal development; for instance, while richer genetic material and genetic diversity can contribute to species resilience, they are not direct advantages of internal development itself. Overall, the enhanced protective advantage of internal development is paramount in the context of reproductive success.
