Question

Match the following situations with the appropriate method of reproduction.
the environment becomes unfavorable quickly
speed of reproduction is necessary
contact with other members of a species is rare
genetic variation is necessary

a. asexual
b. sexual

Answer 1

Here is the matching of the situations with the appropriate method of reproduction:

1. The environment becomes unfavorable quickly - **a. asexual** (Asexual reproduction allows for rapid population increase when conditions are favorable, but if the environment changes quickly, organisms can reproduce quickly in large numbers to potentially survive)

2. Speed of reproduction is necessary - **a. asexual** (Asexual reproduction typically occurs faster than sexual reproduction, allowing for quick population growth)

3. Contact with other members of a species is rare - **a. asexual** (In situations where individuals do not frequently meet, asexual reproduction allows for propagation without the need for mates)

4. Genetic variation is necessary - **b. sexual** (Sexual reproduction facilitates genetic variation through recombination and the mixing of genes, which is important for adaptation and evolution)

So the completed matches would be:
- The environment becomes unfavorable quickly - a. asexual
- Speed of reproduction is necessary - a. asexual
- Contact with other members of a species is rare - a. asexual
- Genetic variation is necessary - b. sexual
