Vitamin K is found in bacteria like E. Coli and aids in blood clotting. Vitamin K aids the body's absorption of mineral calcium, allowing for proper muscle growth and repair.
<h3>What is E. coli?</h3>
E. coli is a Gram-negative, facultative anaerobic, rod-shaped coliform bacterium of the genus Escherichia that is frequently found in the lower intestine of warm-blooded organisms.
Vitamin K, which is found in bacteria such as E. Coli, aids in clot formation.
Vitamin K promotes mineral calcium absorption in the body, allowing for proper muscle repair and growth.
Thus, due to this reason, humans would not be able to repair and grow muscle without bacteria.

Answer:
When patient takes in antibiotics the resistance bacteria gets a competitive survival advantage over the normal sensitive bacteria and hence grows faster.
Explanation:
- Bacteria can acquire resistance by taking in plasmids containing MDR (Multi-Drug Resistance) gene cassettes. The MDR genes produces proteins that can:
- Render the antibiotic ineffective to act on its target by inducing chemical modifications on the drug.
- Promote efflux of the drug from the bacterial cell so that the drug cannot act upon its target.
- When a healthy person ( having no prior exposure to the antibiotic) is infected by bacteria ( both sensitive and resistant varieties):
- A competition develops for the host cells and nutrients between the sensitive and the resistant variety.
- This mutual competition restricts either of the sensitive or resistant bacterial strain to grow profusely.
- When a person (having prior antibiotic exposure), gets infected by bacteria ( both sensitive and resistant varieties) and is exposed to the same antibiotic:
- The sensitive variety, due to its sensitivity towards the drug, gets killed.
- The resistant variety, due to its MDR genes, bypasses the lethal effect of the drug and survives.
- These surviving resistant bacteria can now infect all the available host cells and utilise all the available nutrients without facing any competition and multiply rapidly.

<h3><u>Answer;</u></h3>
<u>The second part of the cell theory</u> which states that the cells are the basic units or the smallest units of living things.
<h3><u>Explanation</u>;</h3>
- <em><u>Cell Theory is the basic theory of biology that describes one of the major characteristics of life. All living things have cells.</u></em>
- The first part of The Cell Theory states that all living things are made of cells.
- <u>The second part of the cell theory states that cells are the basic units or the smallest units and function of living things.</u>
- The third part or the third statement of The Cell Theory states that the cells only come from or originates from living cells.
