Answer: Option B.
Damage to the sun
Explanation:
Damage to the sun is not a negative way we use science because the sun is very far away from the Earth. The sun is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us. This means that The distance from the sun to the Earth is far and it's difficult for science to have negative effects on the sun. The sun is not easily accessible and sun damage is not easily affected compared to pollution, climate Change, overuse of resources which it's as a result of science negative effect.
Answer:
genetic engineering is the process of using recombinant DNA technology to alter the genetic makeup of an organism. genetic engineering involves the direct manipulation of one or more genes.
Explanation:
ggene therapy seeks to alter genes to correct genetic defects and thus prevent or cure genetic diseases. genetic engineering aims to modify the genes to enhance the capabilities of the organism beyond what is normal.

The correct answer is: D. 3H2 + N2 → 2NH3
Ammonia (NH3) is a colourless gas with a characteristic pungent smell with wide use. Ammonia is a common nitrogenous waste, specially among aquatic organisms, and it is a precursor to food and fertilizers to terrestrial organisms. It is used as building block for the synthesis of many pharmaceutical products and cleaning products.
chemistry of the nitrogenous bases are really the key to function the DNA<span>. something called complementary base pairing. cytosine can forms three hydrogen </span>bonds<span> with guanine, and </span>adenine<span> can form two hydrogen </span>bonds<span> with thymine.</span>
