Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. Internal fertilization enhances the fertilization of eggs by a specific male.

I need some answers here
To answer these questions, let's go through each option.
1. Seahorses change color and swim together in predetermined ways before mating. These behaviors are called:
- Asexual reproduction: Asexual reproduction is the process of producing offspring without the involvement of gametes (sex cells) from two parents. This is not the correct answer.
- Sexual reproduction: Sexual reproduction is the process in which two individuals, usually of different sexes, produce offspring by combining their genetic material. This is not the correct answer.
- Courtship rituals: Courtship rituals are behaviors displayed by animals to attract a mate and establish a successful breeding pair. This is the correct answer.
- Budding: Budding is a form of asexual reproduction in which a new organism develops from an outgrowth or bud of the parent organism. This is not the correct answer.
2. A male peacock displays his colorful tail feathers in order to:
- Increase the success rate of asexual reproduction: Asexual reproduction does not involve the display of colorful tail feathers by a peacock. This is not the correct answer.
- Increase the gestation period: The gestation period refers to the time during which an embryo develops in the uterus of a female. It is not related to the display of colorful tail feathers by a male peacock. This is not the correct answer.
- Release gametes into his surroundings: Gametes are released for sexual reproduction, but the display of colorful tail feathers by a male peacock is specifically meant to attract a mate. This is not the correct answer.
- Attract a mate: This is the correct answer. Male peacocks display their colorful tail feathers as part of their courtship behavior to attract a mate.
3. The difference between internal and external fertilization is:
- Internal fertilization occurs outside the male’s body, while external fertilization occurs inside the male’s body: This statement is incorrect. Internal fertilization occurs inside the body of one of the parents, typically the female, while external fertilization occurs outside the body of both parents. This is not the correct answer.
- Internal fertilization occurs outside the female’s body, while external fertilization occurs inside the female’s body: This statement is incorrect. Internal fertilization occurs inside the body of one of the parents, typically the female, while external fertilization occurs outside the body of both parents. This is not the correct answer.
- Internal fertilization occurs inside the male’s body, while external fertilization occurs outside the male’s body: This statement is incorrect. Internal fertilization occurs inside the body of one of the parents, typically the female, while external fertilization occurs outside the body of both parents. This is not the correct answer.
- Internal fertilization occurs inside the female’s body, while external fertilization occurs outside the female’s body: This is the correct answer. Internal fertilization refers to the fusion of egg and sperm inside the female's body, while external fertilization refers to the union of egg and sperm outside the female's body, usually in the environment.
4. A disadvantage of external fertilization is:
- Gametes are released into the surroundings: This is the correct answer. In external fertilization, large numbers of gametes are released into the environment, which leads to a higher chance of them getting dispersed, damaged, or not finding a partner for fertilization.
- Gametes may get washed away: This is not the correct answer. The risk of gametes getting washed away is actually a common challenge in external fertilization, not a disadvantage.
- The developing zygote is protected: This is not the correct answer. External fertilization does not provide protection to the developing zygote, as it is exposed to the environment.
- Large numbers of eggs can be fertilized at one time: This is not the correct answer. While external fertilization allows for the release of large numbers of eggs, it is not considered a disadvantage.
5. An advantage of internal fertilization is:
- Gametes are released into the surroundings: This is not the correct answer. In internal fertilization, the gametes are not released into the surroundings but rather deposited directly inside the female reproductive tract.
- Gametes may get washed away: This is not the correct answer. Internal fertilization reduces the risk of gametes getting washed away, as they are retained within the reproductive tract.
- The developing zygote is protected: This is the correct answer. Internal fertilization offers protection for the developing zygote as it remains inside the female's body, which provides a stable and controlled environment for development.
- Large numbers of eggs may be fertilized at one time: This is not the correct answer. Internal fertilization typically involves the fertilization of a relatively smaller number of eggs compared to external fertilization.
