Explanation:
One activity that can increase genetic variation within a population of earthworms is mutation.
Mutation is a process that results in a change in the DNA sequence of an organism's genome. Mutations can occur naturally due to errors in DNA replication, exposure to environmental factors such as radiation or chemicals, or as a result of genetic recombination during sexual reproduction.
Mutations can be beneficial, harmful, or neutral in their effects on an organism. They can introduce new variations or traits that can be subject to natural selection and influence the evolution of a population. Mutations can also cause genetic disorders or contribute to the development of cancer. The study of mutations and their effects is an important field in genetics and evolutionary biology.

Answer:
A is a eukaryotic cell while B is a prokaryotic cell
Explanation:
The researcher can conclude that cell A is eukaryotic while cell B is prokaryotic.
In eukaryotic cells, the DNA is located majorly in the nucleus and the replication of the DNA happens in the nucleus. Hence, it is only logical to find segments of new DNA in the nucleus of cell A during replication.
Prokaryotic cells, however, lack a nucleus. Their DNAs lie freely within the cytoplasm. This thus means that replication can only happen in the cytoplasm. Hence, it follows logically to find a new DNA segment in the cytoplasm of cell B.
b. Makes mRNA from DNA, binds to DNA, detaches
c. Binds to DNA, detaches, makes mRNA from DNA
d. Binds to DNA, makes mRNA from DNA, detaches
Answer:
D. Binds to DNA, makes mRNA from DNA, detaches.
