Answer:
The correct answer will be option- adhere to cell surfaces.
Explanation:
The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.
The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.
Thus, option- adhere to cell surfaces is the correct answer.
The given statement saying it is proper to put away the knives and the cups in the drawers after towel drying them is false. Towel drying them will make them susceptible to the bacteria. It is better that the utensils should be air-dried. The towel may contain a lot of the microorganisms. They cling to the moist and get transferred to the utensils when the towel is used to dry those dishes.
Hence, the answer is 'false'.
The graph would be the 4th picture, a bell-shaped graph.
The optimum temperature should have the highest rate of enzyme activity. When the temperature is increased or decreased, the enzyme activity would be decreased. The graph that follows both conditions should have a bell shape graph.
I'm pretty sure after water, the most abundant substances in the body are the 6 elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. (:

Answer:
Cell organelle
Explanation:
The cell organelle is the small organ-like structure present inside the cell in the cytoplasm.
Different types of cell organelles are present in the cell which performs specific functions like of storage, of digestion of biomolecules like lysosomes, of protein synthesis and many others.
The organelles are usually enclosed by either a single phospholipid membrane like in lysosomes, Golgi apparatus or two lipid layers like in nucleus and chloroplast.
Thus, cell organelle is the correct answer.
