One similarity between DNA and mRNA is that they both . pls help !!!

B) Both contain genetic codes based on sequences of bases

Explanation:

DNA chemical bases are ATGC, while mRNA chemical bases are AUGC. Uracil replaces Thymine in mRNA, so your answer (option C) is incorrect. However, they are similar in that mRNA carries genetic code from DNA in a cell's nucleus to ribosomes, while DNA contains the genetic information for development and function of living things.

who knows

explanation:

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)
