Answer:
B. The increase is due to industrial point source pollution.
Explanation:
Pollution is the release of harmful substances into land, air or water. The harmful or toxic substances are called POLLUTANTS. According to this question, a community discovers via analysis that its river is now polluted with small amounts of over 20 different chemicals.
This chemicals is a pollutant that can likely emanate from industrial companies and industries that produces these harmful chemicals as waste. Hence, the increase is due to industrial point source pollution.

Give an example of how energy transformations are involved in the development of an energy source.
Answer:
Energy transformations are processes that convert energy from one type (e.g., kinetic, gravitational potential, chemical energy) into another. Any type of energy use must involve some sort of energy transformation.
Energy must obey the laws of thermodynamics.
Thermodynamics is the study of how energy changes from one type to another. The laws of thermodynamics apply to energy and energy conversions.

Why would blood volume play a role in the amount of time a mammal can stay under water?
Answer:
The answer is that they store oxygen in their blood, and in their muscles rather than in their lungs. Marine mammals have a very high blood to body volume ratio. The mammalian diving reflex allows mammals to lower their heart rate and ultimately survive submersion in water for extended periods of time.
Explanation:
The reason why blood volume played a vital role should be explained below.
Role of blood volume:In the case when the oxygen is stored in the blood & in their muscles instead of their lungs so this represents the role of blood volume. Also, marine mammals contain a high blood-to-body volume ratio. It permits the mammals for lowering the rate of heart and survive the submersion in the water for extension of the time. This is the main reason.

There are plenty of resources.
No predators are present.
There are no resources.
Answer:
There are plenty of resources.
No predators are present.
Explanation:
There r plenty of resources + no predators
Exponential population growth happens when there are plenty of resources and no predators are present.
What do you mean by Population growth?Population growth may be defined as the change in population per unit of time.
Exponential growth occurs in the population of continuous breeders. For example, some insects, humans, bacteria, etc.
Exponential population growth requires an enormous amount of resources in habitat and no predator influence.
Therefore, exponential population growth happens when there are plenty of resources and no predators are present.

The flocks all started with 10 birds. Flock
was the most successful at feeding, so it will have the greatest number in the second generation. Flock
was the least successful at feeding and has shrunk the most.
In this scenario, natural selection is affecting many populations of birds with different beak morphologies, which affects how well they can eat the available foods. Each flock initially consisted of 10 birds, but over many generations, natural selection favored some traits over others, changing the population size.
One flock, referred to as "Flock," had the greatest number of second-generation birds because it was the most successful at feeding. Another flock, known as "Flock," had the worst feeding results and has had the greatest shrinkage.

Your question is incomplete, most probably the complete question is:
The flocks all started with 10 birds. Flock was the most successful at feeding, so it will have the greatest number in the second generation. Flock was the least successful at feeding and has shrunk the most. With three foods available, natural selection has favored Flock , which has increased the most in the first three generations. Meanwhile, Flock has declined the most because its beak was the least successful phenotype for the food available.
