Answer:
The correct option is number 3. A deficit of appositional bone growth would not be life threatening.
Explanation:
Appositional bone growth can be defined as the thickening of the bones due to increase in the number of bone tissues at the surface. In this kind of bone growth, the diameter of the bone increases rather than the length of the bone. This can lead to deformation of the bone but it is not life-threatening.
Rest of the options 1, 2 and 3 are serious disorders and can eventually lead to death.
Answer:
there are 4: paracrine signaling, autocrine signaling, endocrine signaling, and synaptic signaling
Explanation:
paracrine:cells that are near one another communicate through the release of chemical messengers
autocrine: a cell signals to itself, releasing a ligand that binds to receptors on its own surface
endocrine:When cells need to transmit signals over long distances, they often use the circulatory system as a distribution network for the messages they send.
synaptic: nerve cells transmit signals. The junction between two nerve cells where signal transmission occurs.

Answers:
#1:
The process that takes place in the stroma in both sunlight and darkness is the Calvin cycle. In sunlight and darkness the Calvin cycle produces a light dependent reaction which then produces ATP and NADPH. Even in darkness the process will still be able to undergo completion. If it has been dark for too long there will not be enough ATP and NADPH to continue sugar production.
#2:
Pyruvate: If there is any oxygen molecules produced in glycolysis will be passed to the Kreb cycle but when there isnt enough oxegen the transport chain wont run which mean fermentation will occur since the NADH molecules have nowhere to go.
NADH: Will go into electron transport.
ATP: Stores energy for a period of time.
#3:
Mitosis and cytokinesis both go through cell division and during mitosis chromatis divides into daughter cells meanwhile cytokinesis has one cell split into two. Without cytokinesis, mitiosis would still happen but only create two nucli in one cell and if cytokinesis happens the cell would die.
