Many prokaryotes are adapted to live inside the body because the majority of bacteria are mesophilic.
Depending on the optimal temperature of development, there are three types of bacteria:
* Mesophilic bacteria prefer average temperatures between 20 and 40 ° C. The majority of bacteria is mesophilic. This is the case of pathogenic bacteria of man and animals, but also commensal bacteria of natural cavities, cutaneo-mucous membranes and especially saprophytic environmental bacteria involved in the degradation and recycling of dead organic matter. (necromass).
* The psychrophilic bacteria have an optimal temperature of development close to 0 ° C.
* Thermophilic bacteria can live at high temperatures (45 ° C in hot springs).
All eukaryotic cells have membrane covered compartment called organelles. They include the nucleus, the Golgi, mitochondria, endoplasmic reticulum and many others. So the answer is- organelles. ;)
Answer:
Reactions require an input of energy to initiate the reaction; this is called the activation energy (EA).
Activation energy is the amount of energy required to reach the transition state.
The source of the activation energy needed to push reactions forward is typically heat energy from the surroundings.
For cellular reactions to occur fast enough over short time scales, their activation energies are lowered by molecules called catalysts.
Enzymes are catalysts
The process that is non-functioning in the person with diabetes is negative feedback mechanism. The correct option is B.
<h3>What is negative feedback mechanism?</h3>
A self-regulating system is a negative feedback loop, also known as an inhibitory loop. Increased output from the system inhibits future production in a negative feedback loop.
When blood glucose levels are too low, the pancreas secretes the hormone glucagon. This travels to the liver in the blood and causes glycogen to be broken down into glucose.
When glucose enters the bloodstream, glucose levels return to normal. This is an illustration of negative feedback.
Thus, the correct option is B.

B. Mitochondria because it converts chemical energy from food in the cell to energy in a form usable to the host cell.
