Answer:
C) The cell's DNA couldn't be packed into its nucleus
Explanation: Histones are protein that arrange DNA into a structural unit that is called nucleosomes. They are located in the nucleus of eukaryotes, DNA wraps itself around histones for it to be packed.
If a cell could not produce histone the DNA wouldn't be packed because its main function is to keep the DNA closely packed in the nucleus.
Histones are also involved in gene regulation.
A scanning electron microscope fires electrons at surfaces, and by detecting scattered electrons that reflect off the surface tells something about the surface topography. Transmission electron microscopy fires electrons through thin samples. The scattering of electrons as they go through the sample tells something about the structure. Both types of microscope utilise electrons in order to image a sample.

Answer:
D. generating electricity in a hydroelectric power plant.
Explanation:
Renewable energy is also known as clean energy and it can be defined as a type of energy that are generated through natural sources or technology-based processes that are replenished constantly. Some examples of these natural sources are water (hydropower), wind (wind energy), sun (solar power), geothermal, biomass, waves etc.
Basically, a renewable energy source is sustainable and as such can not be exhausted.
Generating electricity in a hydroelectric power plant best describes a method of obtaining energy which may cause changes in water temperature and harm to fish populations. This is due to the operation of powerful electric steam turbines operating at high voltage.
