A researcher identifies a strand of genetic material that has the sequence ACCGTA. What is the substance, and how will it be identified?

A. DNA, because it contains the bases A, T, G and C
B. DNA, because it contains the sequece GTA
C. RNA, because it contains the bases A, T, T and C
D. RNA, because it contains the bases A, U, G and C

This nucleic acid is DNA, because it contains the bases A, T, G and C (Option A).

In conclusion, this nucleic acid is DNA, because it contains the bases A, T, G and C (Option A).

Explanation:

There's no u. If there was a u instead of a t in the genetic material, it would be rna

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)

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
