I would say
a. biological pest control
biological pest control is when other plants or animals are used to control pests. There are no chemicals used only the natural roles of the environment.

A) DNA fulfils all three conditions:
<span>(1) copy itself precisely - in the process of replication, DNA copies itself and two molecules of DNA are formed. This process is very precise thanks to the great number of proteins involved in these process that prevents error occurring and proteins that can fix the error if it occurs.
(2) be stable but able to be changed - DNA is very stable molecule otherwise, it cannot be a genetic material. However, its chains can separate in a short length so the translational machinery can attach to it and the process of transcription can occur. Also, in crossing over, during meiosis, </span>the exchange of genetic material occurs and chromosomes change a bit.<span>
(3) be complex enough to determine the organism’s phenotype - it contains a number of genes responsible for different traits. All of this results in the </span>organism’s phenotype.
B) DNA copies itself. <span>Meselson and Stahl conducted the experiments on DNA replication in which they used </span>E. coli<span> bacteria as a model system. After they labelled all bacteria's DNA with heavy 15N by using medium with heavy 15N, they switched bacteria to medium with light 14N. After several generations, all bacteria's DNA was labelled with light 14N. This experiment evidenced that the self-replication of DNA is semi-conservative process.</span>
Answer:
The correct option is D. "Don't worry; fat-soluble vitamins are stored in the body. It takes a lot longer than one day to develop any adverse effects.
Explanation:
Fat-soluble vitamins can be described as those vitamins that can dissolve in fats and can be stored in the body in the form of fat-soluble vitamins. Energy is stored in the body for long terms in the form of fats.
The body does not require vitamins A, D, E and K regularly hence, they are stored in the fat tissues. Depletion of these vitamins in the diet for a day would not cause any adverse effects.
The impact of the automobile, in the US, isn't all positive: streets aren't safe for pedestrians, deer, and other animals, are killed in tremendous amounts on roads, and pollution from car emission harms everyone.
