Answer:

The correct answer is option D) "response to external stimuli".

Explanation:

The phenomenon of tree shedding their leaves during the autumn months is an example of plants response to external stimuli. The deciduous trees start shedding their leaves when light levels and temperatures drop, as a result of the flow of auxin being reduced and the levels of the hormone ethylene rise in the leaves. This process allows the trees to survive winter by conserving resources and protecting from being blown by the winds.

D
This would make the most sense it my opinion because the temperature can play a huge factor in if a tree sheds its leaves or not.

Answer:

Point 3 for kinetic, points 1 and 5 for potential

Explanation:

There is one point that the ball has the most kinetic energy it is at point 3. Point 3 has the most kinetic energy because it has gained the most speed since it was dropped and it also is right before it starts slowing down from trying to go up again. Points 1 and 5 have the most potential energy. When the ball is at point 1 or 5 it is at its maximum height thus it cannot swing any further, so it stops for a split second and gains a large amount of potential energy before it is released into kinetic energy when it falls back down.

What is the main prerequisite for clearance at the G2 checkpoint?
Katena32 [7]

Answer:

The correct answer will be option-accurate and complete DNA replication.

Explanation:

The cell cycle of a cell is controlled by the internal checkpoints where the cell cycle halts until the favourable conditions appear. These checkpoints are G1 checkpoint, G2 checkpoint and M checkpoint.

The G2 checkpoint asses that the DNA replication has been completed, all the chromosomes have been replicated and the replicated DNA is not damaged. The cell cycle stops if the replicated DNA is found damaged.

Thus, option-accurate and complete DNA is the correct answer.
