Prokaryotic organisms have a single origin of replication, whereas eukaryotic organisms have many origins where replication occurs simultaneously. Which of the following is the most probable reason for this observation?

A) Prokaryotic DNA is single-stranded. B) Prokaryotic DNA is much smaller than eukaryotic DNA. C) Prokaryotes do not replicate their DNA. D) Prokaryotic DNA is replicated more slowly than eukaryotic DNA.

B) Prokaryotic DNA is much smaller than eukaryotic DNA

Explanation:

As prokaryotic DNA is circular and much smaller than eukaryotic DNA, DNA repilcation is:

The chromosome of the prokaryotes is a circular molecule of DNA. Replication begins at one origin of replication and proceeds in both directions around the chromosome.

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)
