Option A i.e Pollution made in one country might contaminate the ground, water and air of other countries is the correct answer.

TEA [102]
Hi there!

Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins. 

<span>In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.</span>

Which substance is a compound? <br> salt <br> phosphorus <br> sulfur <br> oxygen
tankabanditka [31]

Answer: The correct answer is salt.

A compound is a chemical substance which is formed by the combination of two or more elements, joined together in a fixed proportion.

Salt is a chemical compound which is formed by the reaction of an acid with a base. For example- NaCl ( sodium chloride) is a common salt. It is formed by the combination of two elements. Therefore, salt is a compound.

On the contrary, Phosphorous (P), sulfur (S) and Oxygen (O₂) are composed of a single element. Therefore, they are not compounds.

Thus, the correct answer for the compound is Salt .
