Some researchers claim that sponge genomes have homeotic genes, but no Hox genes. If true, how would this impact the phylogenetic tree of animals

it's c. (to reduce the greenhouse effect/carbon gasses)

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)

the correct answer is b

i believe your answer would be c.. : )
