hydrogen bonds are intermolecular, that is, occur between molecules or between different parts of one moleculeThe hydrogen bonds are pretty strong hencehydrogen bonds are only about 1/10 as strong as a covalent bond

Answer:
The digestion starts with the buccal cavity or mouth by chewing the food. Teeth break the ham and cheese sandwich into small and digest the starch present in the food with help of the amylase enzyme present in saliva. The small chewed particles of food mixed with saliva called bolus move to the stomach.
In the stomach, there is HCl acid present that killed any harmful microorganism present in the bolus and digests the protein present in the ham and sandwich by pepsin enzyme secreted by the parietal cells of the stomach.
Lipase digest fat present in the cheese of sandwich by gastric juice. Small intestine digest fat by lipase protein by protease and carbs by amylase.
Absorption takes place in the small intestine that contain numerous villi’s projections in the cell lining for absorption in the small intestine.

<u>Answer</u>: Bacteria through the nucleoid (number 5).
<u>Explanation</u>:
Both paramecium and bacteria are single celled organisms. However, they differ by the fact that the first one is an eukaryote and the second one a prokaryote.
Furthermore, they differ in their capacity to mutate and adapt to environmental changes. Bacteria have a simple internal structure that lacks any organelles and are very adept at adapting to environmental changes. Besides their capacity for high mutation rates, they are also capable of picking up genetic information from their environment through a process called <em>transformation</em>.
Through transofrmation, environmental DNA enter the living bacteria through its cell membrane. Double stranded DNA will have one strand dissolved through hydrolysis, whereas the second strand may recombine with the bacterial <em>chromosome (nucleoid)</em>. Thus, this new genetic material will become incorporated into the bacterium's genome.
Only 10% of the energy from prey is passed on to the higher trophic levels of the food chain.
