Answer:
The correct answer is letter C.
Nitrogen fixation is the process where atmospheric nitrogen is converted by bacteria into biologically usable forms.
plant can not take nitrogen directly from the leaves.
The answer is immune system
The bacteria, Angelinus ballerinea secretes a compound that inhibits the growth of other Gram-positive bacteria. Scientists take this compound and add chemical groups to it to make it more stable for use in humans to treat bacterial infections. This is an example of antibiotic.
<h3>
What is antibiotic?</h3>
- Antibiotics from the key class of glycopeptides can stop this process.
- Through five H-bonds, these antibiotics bind to the C-terminal d-Ala-d-Ala of the murein precursor, lipid II, and immature peptidoglycan, preventing transglycosylation and/or transpeptidation during the production of the cell wall.
- Contrarily, antibiotics have easier access to the thick, porous peptidoglycan layer in the cell walls of Gram-positive bacteria, allowing them to more easily enter the cell and/or interact with the peptidoglycan itself.
- The two main antibiotics that prevent the synthesis of bacterial cell walls are penicillins and cephalosporins.
- Penicillin is one of many antibiotics that assault the bacterial cell wall in order to operate.
- The medications specifically stop the bacteria from producing peptidoglycan, a chemical that gives the cell wall the toughness it needs to live in the human body.

Answer:
because you don't get soil like you get the Sun rays everyday. It takes millions of years for formation of soil and you can't get it within the lifespan of one human. Hence it is considered as Non-Renewable resource.
