Michael’s mom drops him off at school early two days a week. Michael likes to use this time to get his homework done for the week. A disadvantage of this study time is that a. He is always wide awake in the morning c. His friends aren’t there to help him do his homework b. It is not available to him everyday d. All of these

hope this !

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

why do you want to cheat? i dont take it, so i dont know.

explanation:

some tips: get a tutor

study

ask for

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)
