Answer:
A.it travels at a different speed
bisible energy from the sun is different from the non visible energy.
Answer:
Radio waves, microwaves, infrared and visible light can all be used for communication.
The result which would be seen from a properly prepared negative control is nothing.
<h3>What is a Negative control?</h3>
This type of control is used to test and ensure that in the absence of the antigen we do not still get a positive reaction.
Since proper aseptic technique was practised and there was no swabbing of the surface then there would be nothing seen in the properly prepared negative control.

DNA replication is the process by which two DNA molecules are produced from one parent DNA molecule. DNA replication is semi conservative, this implies that, each strand in the double helix DNA molecule act as a template for the synthesis of a new, complimentary DNA strand. Because semi conservative method has a DNA template that is already accurately formed, the probability of having errors in the newly formed strand is drastically reduced.
Answer: The correct answer is B) Vaporization.
A process is called endothermic when it absorbs energy from surrounding. In other words, if energy is consumed in any process then it is termed endothermic change. When any process releases energy in the surrounding then it is called exothermic process.
In vaporization, energy is absorbed by water molecules, which form vapors. Thus, it is an endothermic change.
On the contrary, in condensation, deposition, and freezing, the new bonds are being formed and thus energy is released in the surrounding. Therefore, they are exothermic process.
