Explanation:
Gravitational potential energy is the energy of body due to its position in the gravitational field.
Whereas chemical potential energy is the energy within the chemical bonds of a substance.
For example, when we eat an apple then we get energy in our body so, it is the chemical potential energy stored in the apple.
Items sorted on the bases of gravitational potential energy and chemical potential energy are as follows.
Gravitational potential energy:
- a ball thrown up in the air.
- a stone rolling downhill.
- water stored in an overhead tank.
Chemical potential energy:
- liquid petroleum gasoline used in cars.
- firecrackers that people set off.
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.
<span>A scientist wants to create a florescent ornamental fish. He needs fluorescence similar to that of a firefly. Which of the send processes would help him create this fish?
The correct answer is </span><span>transformation of the DNA of a fish using a fluoroscent gene from a firefly. In order to do so, he would have to use the gene of the firefly as a reference in order to transform the DNA of a fish.</span>
