Viral infections _____. can be treated with antibiotics often can't be treated can be prevented with immunization can be contracted only from direct contact with someone infected

Answers

Viral infections often can't be treated because viruses stay inside the body's cells. This makes it hard to find a cure for them. The best way to treat viral infections is by treating their symptoms. Some infections can be prevented with vaccines as well. They can be transmitted through direct contact with an infected person or via a medium such as air.

I believe the answers are

- often can't be treated

- can be prevented with immunization

- can be treated with antibiotics

Why is preventing pollution at its source the first strategy in minimizing environmental risk?a.

It is easier and more effective to prevent pollution than to clean up and dispose of waste.
b.

Remediation of contamination is easier than pollution prevention.
c.

Habitat restoration cannot be undertaken with modern technologies.
d.

Safe waste disposal is the easiest was to minimize environmental risk.

Answers

The control of pollution is key to minimize environmentalrisk due it is easier and more effective to prevent pollution than to clean up and dispose of waste (option A).

What is pollution?

Pollution refers to the contamination of water, air (atmosphere), and soils with nocive substances that may be harmful to the environment.

  • Pollution may also be harmful to human health, as well as to life in the surrounding ecosystems (either aquatic or terrestrial ecosystems).

  • Pollution may significantly alter the delicate internal equilibrium (homeostasis) of the whole ecosystem.

In conclusion, it is easier and more effective to prevent pollution than to clean up and dispose of waste (option A).

The correct answer for this question is a) It is easier and more effective to prevent pollution than to clean up and dispose of waste.

Yes, it is more effective way to control environmental risk by preventing pollution at its source. First it help us to control the flow of toxicity through water and air. It is often more difficult and expensive to control pollution after it has been released into the environment so it will also help us to cut the cost of treatment of pollutants

25. to conserve water, an animals kidneys can pump ions across cell membranes, allowing water to move by________?

Answers

Answer:

Active Diffusion

Explanation:

In active transport, a molecule is transported against its gradient which means the flow of molecule is from regions of low concentration to regions of high concentration. In order to carryout such transports, external energy is applied through biological pumps such as sodium-potassium pump (Na+/K+ ATPase)  which maintains the resting potential of the cell.  

Some times the energy produced by ATP is directly used and this process is known as primary active transport/diffusion
active deffusion.. this way the water is retained and the unnecessary salts ions are expelled out.

Name one type of cell that uses active transport
Which statement best relates science and societal problems? Societal problems are the result of science. Any societal problem can be solved by using science. A scientific solution to a societal problem does not result in further problems. Science can be used to address societal problems, but it is not always successful.
A wildlife biologist suggests re-introducing the eastern cougar into southern Alabama, reasoning that besides bears, which can survive off of berries and grubs, there are no large natural predators, and that it would be good for the food chain. It is assumed that the eastern cougar would eat deer, which in turn, graze on tree bark, shrubs, and leaves. The average cougar weighs about 100 pounds, as does the average deer. The average cougar has a range of one square mile. A recent biological study showed that there were about 16 deer per square mile in Alabama, an average about 40,000 pounds of vegetation per square mile, and an average of 9.5 people per square mile in southern Alabama. Despite the biologist's proposal, other biologists vote against re-introducing the cougar. Which of these is a possible VALID reason for this?
