One of mom's chromosome 7's has a nonfunctional CTFR allele (cf−) next to a functional allele of another gene (A+). Her other homologue has a functional allele of the CTFR (CF+) gene next to a nonfunctional allele of the other gene (a−). Dad has functional alleles of both genes on both homologues (CF+, A+). A child of theirs has a maternal homologue that is CF+, A+; and a paternal homologue that is also CF+, A+. The best explanation for this is .

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

so whats the answer

the answer is c. it will give up it's valence electron to the other atom.
