Here’s a matching of the situations with the appropriate method of reproduction:
-
The environment becomes unfavorable quickly - Asexual
- Asexual reproduction allows for rapid population increases which can be beneficial in changing environments.
-
Speed of reproduction is necessary - Asexual
- Asexual reproduction typically allows for faster reproduction rates compared to sexual reproduction.
-
Contact with other members of a species is rare - Asexual
- In cases where contact is rare, asexual reproduction allows organisms to reproduce without needing a mate.
-
Genetic variation is necessary - Sexual
- Sexual reproduction promotes genetic diversity through the combination of genetic material from two parents, which is crucial for adaptation and evolution.
So the matches are:
- The environment becomes unfavorable quickly - Asexual
- Speed of reproduction is necessary - Asexual
- Contact with other members of a species is rare - Asexual
- Genetic variation is necessary - Sexual
