Explain why the chemical released from the injured fish may not cause an alarm response in other fish species

Biology
1 answer:
Serggg [28]3 years ago
4 0
There is an evolutionary reason why such mechanisms would only work within species: Fish would get an advantage (as a population) from warning their co-specifics, but not from warning other species. So they would (through the process of evolution) tweak their signals to be only readable by the same species.

What does the smooth ER do?
Svetradugi [14.3K]
<span>Endoplasmic reticulum (ER) is a network of interconnected sacs (cisternae). Depending on the presence of ribosomes on the surface of their membrane, ER can be rough or smooth. Smooth ER does not have ribosomes on the surface of its membrane. Smooth ER plays a part in lipid production and metabolism, as well as in the production of steroid hormones. It is also involved in detoxification of organic chemicals, products of natural metabolism, etc.</span>

Which of these disruptions would cause an excess output in the Carbon Cycle?
blagie [28]

Complete Question:

The carbon cycle includes processes that release carbon into the atmosphere and places that act as carbon reservoirs. The diagram below shows both major processes that release carbon and major carbon reservoirs. (See attached picture for the diagram being referred to)

Which of these disruptions would cause an excess output in the carbon cycle?

 A. The destruction of terrestrial biota

 B. Increases in marine biota

 C. A reduction in the use of fossil fuels

 D. A thickening of ocean sediments

Answer:

A. The destruction of terrestrial biota

Explanation:

Terrestrial biota play a very cogent and fundamental role in the regulation of carbon in the carbon cycle. Serving as a reservoir of carbon, terrestrial biota helps in absorbing carbon dioxide from the atmosphere.

Therefore, the destruction of terrestrial biota would lead to an excess output of carbon in the carbon cycle due to the reduction in the capacity of forest and other plant community to absorb carbon dioxide from the environment.

Destruction of terrestrial biota would result in an excess output in carbon when compared to other disruptions.
