The answer is true. They cannot only replicate themselves within cells, but they cannot outside of a cell.
Answer:
A. They have different genetic sequences but are found in the same location on a chromosome.
Explanation:
In genetics, alleles are the variant form of a gene. According to Mendel, there are usually two alleles for most genes except for few cases where there are multiple alleles. Each allele of a pair is contributed by each parent during sexual reproduction. For example, in a gene Tt, the alleles are T for tallness and t for shortness.
Alleles of the same gene are related in such a way that they have different genetic sequences but are found in the same location on a chromosome. The different genetic sequences makes them alternative form of each other.
A pyramid of energy can never be inverted because energy decreases by tenfold each level. This can't be reversed because energy can't just increase by tenfold. It has to come from somewhere.
