Answer: b. Increased nutrient run-off
Explanation:
Nutrient run-off is when an excessive amount of nutrients like Nitrogen and Phosphorous find themselves in bodies of water. This acts as a fertlizers and promotes algae growth.
This algae growth compromises the qualiy of water and depletes the oxygen in the water. This essenfially harms the habitat thus this is noy an ecological benefit.
“Two species of crickets, Gryllus rubens and
Gryllus texensis, have different courtship songs which can be identified only
by the opposite sex of their own species” is an example of behavioral isolation.
Behavioral
isolation<span> is an
important evolutionary mechanism that helps members of the same species
identify each other as proper mates.</span>
The correct answer between all
the choices given is the third choice or letter C. I am hoping that this answer
has satisfied your query and it will be able to help you in your endeavor, and
if you would like, feel free to ask another question.
The scientist can tell that punctured equilibrium has occurred if they have examined the fossil fuels and can see that one organism rapidly evolved different characteristics.
Answer: Option D
<u>Explanation:</u>
Punctured Equilibrium is an evolutionary theory which proposes that the species appearing in the fossil's record will show little evolutionary changes. In punctuated equilibrium, change occurs gradually, First very little change can be seen which later results in the occurrence of huge changes.
Such huge changes can be clearly seen by examining the fossil records. Thus if there is any evolutionary changes seen in the fossil's record, the scientist can conclude the occurrence of punctuated equilibrium.
Answer:
Intervention and prevention programs on college drinking could incorporate education about strategies for self‐control, including strategies for withstanding peer pressure and diverting one's attention to activities unrelated to substance use. Focusing on strategies of self‐control may be a useful starting point for a more in‐depth discussion about the motivations, values, and psychological needs satisfaction that are associated with drinking and other drug use.
