Answer:
Point-source pollution is easy to identify. As the name suggests, it comes from a single place. Nonpoint-source pollution is harder to identify and harder to address. It is pollution that comes from many places, all at once.
Answer:
The answer is A - The populations will not be able to interbreed because they are different species and different species cannot interbreed
Explanation:
The population of birds become reproductively isolated because they are different species and different species are unable to interbreed. This is as a result of barriers which are called mechanisms of reproductive isolation which involves mechanisms, behaviors and processes that are critical for speciation. In reproductive isolation the different species are able to live in the same are but their properties and characteristics do not allow them interbreed to produce healthy and sterile offspring.
Answer:
Geological events can cause drastic changes over long periods of times
Explanation:
He used these insights and stated that Geological events can cause drastic changes over long periods of time. Such changes can cause entire species to become extinct or cause drastic evolutionary physical changes to other species. This is because the environment changes and the animals living in these environments need to adapt in order to be able to survive. Some changes such as continental drift can even move species to different parts of the world where the climate is drastically different.
Answer: Enzymes are organic bio-molecules that catalyze the chemical reactions in biological system. Similar to catalyst, an enzyme accelerates the rate of a chemical reaction and it is neither consumed nor changed in the reaction. Therefore, the enzymes are also called bio-catalysts.
