Hydropower can be harnessed from flowing and falling water. Water stored behind dams and at a height has a lot of potential energy which is converted into mechanical and electrical energy.This water is released gradually and is made to fall under the force of gravity and drive hydraulic turbines and electri­cal generators. Hydropower is also another indirect form of using solar energy. Hydropower has great potential as a supplier of electricity but environmental constraints limit such a development as the generation of electricity by hydro­electric power plants result in pollution and massive ecological disruptions such as land flooding, siltation, eutrophication and adverse effects on flora and fauna. Smaller dams and reservoirs cause less damage but cannot exploit the full potential of this energy resource. Planning environmental impact assessment and construction of a hydroelec­tric power plant takes many years and the high initial capital investments are also limiting factors in the development of hydropower. The development cost of hydroelectric power plants can be reduced by developing low cost turbines and generators, involving public participation in the development and opera­tion of the project and using efficient environmental friendly technologies.

Irina18 [472]
 A Fourier analysis is a technique that is able to determine both the amplitude spectrum and the phase <span>spectrum of any signal</span>. This analysis is based on the finding that all sound waves can be derived by adding sinusoids together (so long as the sinusoids are of the appropriate frequencies, amplitudes, and phases).

Pepsin, an enzyme that is found in the stomach of humans, functions in breaking down proteins. It is denatured as it travels to
AnnZ [28]

Answer:

A. pH

Explanation:

Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.

However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.

The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.

Explain how the environment play a role in changing the frequency of a mutant allele in a poplution
tiny-mole [99]

Answer:

The environment plays a role in a mutant allele in a population because some mutations are more beneficial to the organism than other mutations.

Explanation:

Organisms with a beneficial allele mutation will be able to pass on their genes as they reproduce. The mutation makes them <em>fit</em> for survival in their environment. Other organisms <em>without </em>the beneficial allele won't be able to pass on their genes since it will be more difficult for them to survive in their environment. Natural selection will deem that the organisms with the mutation will survive better and be able to produce offspring with the same mutation.

What is the purpose of using reverse transcription
Angelina_Jolie [31]

Answer:

reverse transcriptase (RT) is an enzymeused to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. Reverse transcriptases are used by retroviruses to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes, and by some non-retroviruses such as the hepatitis B virus, a member of the Hepadnaviridae.
