Answer:
D
Explanation:
Geothermal energy utilizes the natural heat of underneath rocks to heat water to steam. The steam is then used to turn turbines and generate electricity. The water is usually recycled by being injected back to the ground to make sustainable use of the water. However, this process of injecting water in the ground may contaminate the groundwater in aquifers. The water can, therefore, be unsuitable for human use such as watering of plants and animals including household use.

Here is a scientific theory chart
Answer:
Option (b).
Explanation:
Melting temperature may be defined as the temperature at which the DNA strand melts. The melting temperature depends on the Guanine and cytosine content of the DNA.
The thymine binds with Adenine with two hydrogen bonds whereas cytosine binds with guanine with three hydrogen bonds. More energy is required to break the guanine cytosine bonds and they have high temperature. The second strand 5'-ACGGCTACG-3' contains more GC content and hence have high melting temperature.
Thus, the correct answer is option (b).
The human skin is the protective layer of the human body against the external forces like the temperature, sharp objects, microbes, fungi and other related materials that can penetrate and weaken the body however, the integumentary system prevents any harm come to the organism.
