Question

4 multiple choice 2 points which will most likely cause variations to occur within a species? mutation mutualism predation competition 5 multiple choice 2 points identify \c\ gene p arm centromere q arm

Explanation:

For question 4, mutations are changes in DNA sequences that can introduce new traits and cause variations within a species. Mutualism is a symbiotic relationship, predation is one - organism eating another, and competition is organisms vying for resources, none of which directly cause genetic variations within a species like mutation does. For question 5, the segments on a chromosome that code for traits are genes. The p - arm and q - arm are parts of the chromosome structure relative to the centromere, and the centromere is the constricted region of the chromosome.

Answer:

1. mutation
2. gene
