Which is not an impact to the ecosystem after a drought?

Biology
1 answer:
Nadya [2.5K]3 years ago
3 0

Answer:

A. Floods will wipe out all the vegetation

Explanation:

Drought is an environmental condition characterized by scarcity of water. Less rainfall and reduced ground water levels facilitate drought like conditions. In the event of drought, animals face difficulty in finding food and water and thus are forced to migrate to other areas. However, flood is exact opposite to drought. It is caused by excess rainfall or increase in water level which destroys the ecosystem. It is not a characteristic of drought.

Regulation of heart rate, blood pressure, and digestive functions are carried out by the ______________________.
Svetach [21]

Regulation of heart rate, blood pressure, and digestive functions are carried out by the <u>autonomic nervous system</u>

<u></u>

What is autonomic nervous system?

The peripheral nervous system's autonomic nervous system (ANS), originally known as the vegetative nervous system (VNS), provides smooth muscle and glands, which in turn affects how internal organs work. The autonomic nervous system is a control system that regulates body processes like the heart rate, digestion, respiratory rate, pupillary response, and urination mainly subconsciously. The fundamental mechanism in charge of the fight-or-flight response is this system.

Through the brainstem, the spinal cord, and the organs, integrated reflexes control the autonomic nervous system. Control of respiration, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and other reflex acts including coughing, sneezing, swallowing, and vomiting are all examples of autonomic functions.

Suppose that, among related host species that carry related symbionts, the relationship is mutualistic in some pairs and parasit
romanna [79]

Answer & Explanation:

a) a) Mutualistic relationship differs from parasitism because the first one benefits both of the involved organisms. Otherwise, parasitism benefits only one of the organisms and it can harm the host. Therefore, the parasite would have to be smaller than the host and it would be somehow extracting energy from the host.

b) The direction of evolutionary changes would follow some kind of pattern, like coevolution. Therefore, analyzing the phylogenies individually and then contrasting them, would help to understand how the host, as well as the parasite, have been evolving.

c) The phylogeny would also help to understand what changed first, or if they changed together as a result of coevolution.
