An open system starts with 52 J of mechanical energy. The energy changes to 45 J of mechanical energy and 2 J of thermal energy. What is the final total energy of the system? 50J
47J
9J
54J

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

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)
