In the study of human evolution, scientists define modern in terms of: a. a series of anatomical traits that distinguish cro-magnon features from neandertals. b. a designated time frame between the upper and lower paleolithic. c. a series of distinctive anatomical traits that contrast with archaic traits from earlier hominins. d. traits like large browridges, large nasal sinuses, and a large masticatory complex.

 a)  a series of anatomical traits that distinguish Cro-magnon features from Neandertals.

Neanderthals (Homo neanderthalensis) were first discovered in Germany in 1856 and are believed to emerged between 100,000 and 200,000 years ago.

Significant differences found in the human and Neanderthal includes: 1) their DNA, 2) the brain of a Neanderthal had a raised larynx and was also bigger, and  3) Compared to modern humans, Neanderthals had bigger and muscular body but with shorter legs.

Cro-magnon is the earliest known Western European example of our species who lived  35,000 and 10,000 years ago. They are believed to be actually modern in every anatomical respect. They are much like us.

Neanderthal and Cro-magnon were believed to overlap in Europe for a thousand years but long-term interbreeding was not seen. 

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)
