The answer is; genetic diversity
Genetic diversity is the number of genetic characteristics in a population. Genetic diversity is important in a population especially in its adaptability to a changing environment. The diversity is acted upon by natural selection and enables the population to evolve with the changing environment.
Thalamus and Prefontal cortex (PFC)
<span>Thalamus is known to be a
small region that is found at the center of the brain and function by relaying
signals to the eyes, mouth of the brain and function by relaying signals from
the eyes, skin, mouth and ears to the other part of the brain for processing.
However, prefontal cortex is the region of the brain that is involved in
planning complex cognitive behavior, decision making and personality
expression. Also, prefontal cortex are considered to be involved in thought
orchestration and support concrete rule learning.</span>
Answer:High pH levels (9-14) can harm fish by denaturing cellular membranes. Changes in pH can also affect aquatic life indirectly by altering other aspects of water chemistry. Low pH levels accelerate the release of metals from rocks or sediments in the stream.
Explanation:
Euthrophication is caused by excess nutrient run off, such as nitrogen or phosphorus. A common chemical that generally cause euthrophication is fertilizers from farm, if there's heavy rainfall or floods, they're easily washed into the rivers and lakes to cause euthrophication.
Euthrophication generally cause a sudden large scale algao bloom, or other plants, and they may cover the whole surface of water. Once these plants die, decomposers such as bacteria decompose them and take in oxygen for respiration, such that animals from the river originally may die due to lack of oxygen.
