What is one way that fish interact with a coral reef?
Ksivusya [100]

Fishes use the coral reef for shelter during the day as well as food.

<h3>Information related to coral reef</h3>

One way that fish interact with a coral reef is that fish hide within the coral. Coral reefs are an important resource for large-bodied fish in the Caribbean. They use the reef for shelter during the day.

Coral reefs are important ecosystems because coral reefs contain a great diversity of life. The color of coral depends on the type of polyp present. Coral polyps are tiny little animals that can live individually, or in large colonies that comprise a coral reef.

Great Barrier Reef is considered as the largest coral reef on Earth. Coastal land development, silt runoff, water pollution by humans, damage from scuba diving, boating, and fishing are the threats to the health of coral reef.

Which of these is likely to result in the most competition? A. organisms that live in different ecosystems B. organisms that use
Serhud [2]
It wouldn't be A because the animals wouldn't really be bothered by each other in the first place. They're not in the same ecosystems..
It wouldn't be D because these animals would be ranked the same if they were in the same phylum.
It could be C, but it's not because there is a variety of other resources for them to use. 
I think B would be the best answer because they are fighting each other for the same resource. You need that resource in order to survive and so does that other organism, so of course both organisms would be fighting over it in order to live

hope this helps!

Which cell type in Human lacks a nucleus? What function would this cell be unable to carry out?
AnnZ [28]

Answer:

Red Blood Cell lacks a nucleus, it would be unable to carry oxygen efficiently.

Explanation:

The absence of a nucleus is an adaptation of the red blood cell for its role. This allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its own distinctive bivalve shape, which promotes diffusion.
