Answer:
I think the answer will be protein.
Bacteria are the simplest single cells that carry out all basic life activities.
Hope this helps!
Have a great day! :D

The end products of electron transport chain are:
Water
Adenosine triphosphate (ATP)
Explanation:
- Most of the free energy released during the oxidation of glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
- Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
- These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.
- The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP
D is the answer. A gene is a part of a chromosome.
Glucagon
This is a hormone that deals with blood sugar homeostasis. When blood sugar levels are low, glucagon is produced to convert the fats in the reserve back to glucose until normal levels are achieved.
Explanation:
Bone remodeling involves coordinations of osteoclasts and osteoblasts cells in the bone. The former breaks down bone tissue while the latter mineralizes bones. Calcium is the main ion in the body significant in mineralization of bone. Excess Ca2+ is stored in bone while low calcium levels in blood result in bone resorption.
Stress on a bone also causes increased mineralization to strengthen the bone against this stress. This is why astronauts when they go to space, due to less stress from low gravity, bone loses its mass. When they return back to earth, the bone readjusts to the increased stress from higher gravity by increased mineralization.
The hormone responsible for bone homeostasis is parathyroid hormone.
