Answer: Light is a form of electromagnetic radiation. Other forms of electromagnetic radiation include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays, and gamma rays. The only difference between them is their wavelength, which is directly related to the amount of energy the waves carry. Scientists classify them by the frequency of their wavelength, going from high to low frequency. When a wave has a lot of energy, it could be a gamma ray or x-ray. If it has low frequency, it has less energy and could be a TV or radio wave.

Answer:
Option-D
Explanation:
Captive breeding or breeding in the captivity is the conservation technique employed by the government to conserve nature.
Captivity breeding is also known as the captive propagation of animals in which animals are kept either in their natural habitat (ex-situ conservation) or in artificial conditions like in zoos where condition similar to the habitat of animal are created.
The breeding programme aims at conserving the natural habitat of the animals to prevent the endangered species from extinction. The endangered species are at risk of extinction due to loss of fragmentation, pollution, predation and others.
Thus, Option-d is the correct answer.
Answer:
p53 helps the cells from passing on mutations that lead to DNA damage. Hence, it is known as the guardian angel of the cell as it helps fight against cancer. However, if p53 becomes defective or missing, then the mutations will lead to cancer.
Mutations in the p53 can also cause the tumor-suppressing genes to convert into tumor causing genes. Hence, mutations in such kind of genes can be very harmful for the body.
Valine is a hydrophobic amino acid used for biosynthesis of proteins. It is essential in humans, meaning the body cannot synthesize it and it must be obtained from the diet.
Glutamic is a hydrophilic amino acid used by almost all living beings in the biosynthesis of proteins. It is non-essential in humans and the body can synthesize it.
