Explanation: Natural resources are resources provided by nature. They occur in nature without manmade interference. Natural resources include mineral deposits, land water bodies and the atmosphere. These resources are utilized by man for economic, social and educational purposes. Natural resources can be renewable or nonrenewable resources such as water are renewed by rainfall. Heavy manmade activities such as industrialization, war or natural disasters can deplete these resources.

Answer:
Biotechnology.
Explanation:
Biotechnology may be defined as the field of biology that uses the living organisms to make product by using molecular techniques. Biotechnology involves the different field like biomedical engineering, biomanufacturing and bioengineering.
The genetic system of the living organism can be modified to obtain the desired products. Artificial insulin is prepared by the application of biotechnology. The new drugs in the market and desired trait in the living organism can be prepared by the biotechnology field.
Thus, the correct answer is biotechnology.
I remember the secondary structure by visualizing it. Understand that primary structure is just the order of the amino acids. The tertiary structure is the 3dimensional configuration of the whole protein molecule with multiple interactions guiding its fold (disulfide bonds, ionic interactions, hydrogen bonds, van der walls). Secondary structure is a step towards the conformation of the protein where it is made up of either alpha-helices or beta-pleated sheets. The alpha helices look like a spiraling staircase while the beta-pleated sheets look like a repetition of long loops. These two structures hold itself by hydrogen bonds.
