Copied, I agree with the person above ^ :’)
C Pollutant just like emissions or oil spills
Condensation is the process by which water vapor is changed back into liquid water. Condensation is very important to our weather and climate because it is what is responsible for cloud formation.
Without clouds, we would not get to the third phase, called precipitation, which we will talk about in a minute. Clouds form when water vapor condenses around small particles, like bits of dust or smoke in the air. Depending on the size of the drops, these particles may or may not be visible. Even on a clear, cloudless day, water vapor is always present in the atmosphere, but it does vary in amounts. We know it is present on a very humid day; it often feels like we need to swim through the air! Fog is condensation near the ground.
<span>Fog forms when moist warmer air comes in contact with cooler air near the surface. Just like when the bathroom mirror gets all foggy during a shower because of condensation, fog also forms because of this warm air contacting a cooler air mass. The fog forms drops in the air rather than on the surface of your mirror.</span>Clouds will be useless since they will not carry and drop water.
Answer:
The correct answers will be option-B
Explanation:
The polymerase chain reaction is the technique which involves the chain of reaction. The reactions are performed which polymerises or make exact copies of the DNA in higher number from a small sample in vitro-conditions.
The PCR technique is based on the DNA replication mechanism which involves the DNA primers and Taq polymerase, a type of DNA polymerase enzyme.
The PCR proceeds in three steps that are denaturation, annealing, and extension in which the DNA is denatured to break the hydrogen bonds, the addition of the primers at both ends called reverse and forward primers which function simultaneously, synthesis of DNA and extension in which the sample is cooled.
Since the primers are added to both the strands and not on the same strands therefore, the selected option is the correct answer.
