This is a cellular respiration question, related to biology.
Some processes in our bodies require the use oxygen, others do not.
In this case, the conversion of pyruvic acid to acetyl co-enzyme A and the production of water in the electron transport chain do require oxygen.
If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. Water in the ETC is formed in the process when NADH and FADH2 are converted to molecular oxygen due to the electron transporters. The protons are then pumped and oxygen is reduced to form H2O.
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.
Birds have hollow bones due to the fact thay need to be as light as possible for their wings to generate enough lift for them to fly
Capillary action is a combination of the adhesive and cohesive properties of water in which the water is able to move up a small tube against the pull of gravity. Therefore, the uptake of food and water is due to capillary action.
Change in climate has nothing to do with adhesion and cohesion in water. Some insects can walk on water due to surface tension, which is due to cohesion. However, there is no movement upward through a tube with surface tension, and so it is not an example of capillary action.
Hope this helps! :)
