An anthropologist discovers the fossilized heart of an extinct animal. the evidence indicates that the organism's heart was large, was well-formed, and had four chambers, with no connection between the right and left sides. a reasonable conclusion supported by these observations is that the:
a) animal had evolved from birds.
b) animal was endothermic and had a high metabolic rate.
c) animal was most closely related to alligators and crocodiles.
d) animal was likely an invertebrate animal.
e) species had little to no need to regulate blood pressure.

B

Explanation:

animal was endothermic and had a high metabolic rate

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)

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this
