It is useful for the walls of capillaries to consist of a single layer of thin, flattened cells in order to easily diffuse oxygen and nutrients easily from the blood and into the capillaries. Not only that, but this also makes it more efficient for carbon dioxide and other waste molecules to diffuse from the capillaries and into the blood. If capillaries were thicker than a cell, then it would be more difficult for materials to diffuse through the thick layer of cells.
The enzyme which digests proteins in pineaapple called BROMELAIN becomes inactive when heated to a certain temperature of about 160°F, hence cooked or heated pineapple would be unable to digest gelatin since the enzyme has been deactivated.
- Pineapples usually contain a protein digesting enzyme called BROMELAIN, this enzyme prevents gelatin from solidifying.
- However, these enzyme becomes inactive at certain temperature level of about 160°F.
- Therefore, when pineapple is cooked, BROMELAIN becomes inactive and can no longer digest protein.
Therefore, the temperature in which cooked pineapple is subjected to deactivates BROMELAIN and hence, enzyme can no longer digest protein.

Answer:
Pili
Explanation:
The sex of bacteria is determined by a structure called Pilli. Pilli is not present in all species of bacteria, but within species that have this structure, such as Escherichia coli, pilli is considered an appendage present in male bacteria.
Pilli presents itself as a long hair and can also be called F factor or fertility factor and has a reproductive function, as it allows the conjunction between two bacteria (one with pili and the other without), where the male bacteria transmit genetic resources to within the body of the female bacteria , which will combine these resources with its own resources and will give rise to another bacteria.
