Explain why volcanoes form at both convergent plate boundaries and divergent plate boundaries.

Answers

Answer:

Volcanoes often form along tectonic plate boundaries where oceanic plates sink beneath other plates. As a plate sinks deep into a subduction zone, it will start to heat and melt, forming something called magma. Volcanoes can also be created near tectonic boundaries where plates pull apart. This allows magma to rise up from the mantle.

Which best describes why active transport requires atp to move molecules across the cell membrane?

A. Molecules are moved with the concentration gradient

B. Molecules are moved against the concentration gradient

C. No net movement of molecules needs to occur

Answers

Answer:

B. Molecules are moved against the concentration gradient.

Explanation:

Due to the higher concentration of the molecules of one of the sides than the other,in order to move molecules from the side with higher concentration of molecules to the side of lower concentration of molecules which is against the movement of molecules across the membrane, energy must be applied i.e atp.

The reason active transport requires ATP to move molecules across the cell membrane is because molecules are moved against the concentration gradient.

ACTIVE TRANSPORT:

Active transport is a type of cellular transport that requires the input of energy in form of ATP. Examples of active transport are pumping of Na+/K+ ions, exocytosis etc.

Active transport requires ATP because molecules are being moved against concentration gradient. This means that molecules are moved from regions of low concentration to that of high concentration.

Passive transport, which does not require energy, moves molecules down a concentration gradient.

Therefore, the reason active transport requires ATP to move molecules across the cell membrane is because molecules are moved against the concentration gradient.

Until recently, we have had to fear that the United States might be attacked by atomic bombs during this war and that her only defense might lie in a counterattack by the same means. Today, with the defeat of Germany, this danger is averted and we feel impelled to say what follows: The war has to be brought speedily to a successful conclusion, and attacks by atomic bombs may very well be an effective method of warfare. We feel, however, that such attacks on Japan could not be justified, at least not unless the terms which will be imposed after the war on Japan were made public in detail and Japan were given an opportunity to surrender. If such public announcement gave assurance to the Japanese that they could look forward to a life devoted to peaceful pursuits in their homeland and if Japan still refused to surrender our nation might then, in certain circumstances, find itself forced to resort to the use of atomic bombs. Such a step, however, ought not to be made at any time without seriously considering the moral responsibilities which are involved. The development of atomic power will provide the nations with new means of destruction. The atomic bombs at our disposal represent only the first step in this direction, and there is almost no limit to the destructive power which will become available in the course of their future development. Thus a nation which sets the precedent of using these newly liberated forces of nature for purposes of destruction may have to bear the responsibility of opening the door to an era of devastation on an unimaginable scale. If after this war a situation is allowed to develop in the world which permits rival powers to be in uncontrolled possession of these new means of destruction, the cities of the United States as well as the cities of other nations will be in continuous danger of sudden annihilation. All the resources of the United States, moral and material, may have to be mobilized to prevent the advent of such a world situation. Its prevention is at present the solemn responsibility of the United Statessingled out by virtue of her lead in the field of atomic power. . . . In view of the foregoing, we, the undersigned, respectfully petition: first, that you exercise your power as Commander-in-Chief, to rule that the United States shall not resort to the use of atomic bombs in this war unless the terms which will be imposed upon Japan have been made public in detail and Japan knowing these terms has refused to surrender; second, that in such an event the question whether or not to use atomic bombs be decided by you in light of the considerations presented in this petition as well as all the other moral responsibilities which are involved.DISCUSSION QUESTIONS1.
