Answer:
The correct answer is 18 ATP and 12 NADPH and noncyclic photophosphorylation can produce ATP molecule in the absence of cyclic photophosphorylation.
Explanation:
ATP and NADPH molecules are synthesized during light reaction of the photosynthesis which is utilized during the reactions of the dark phases. Dark reaction or Calvin cycle (C3 cycle) is the cyclic pathway of producing glucose triose phosphates (3C) from carbon dioxide and water. This reaction proceeds into 3 phases: carboxylation, reduction and regeneration.
First ATP and NADPH are utilized during the reduction step in the reduction of 3-phosphoglycerate to glucose-3-phosphate by the transfer of phosphate group from 6 ATP to 3-phosphoglycerate and 6 NADPH reduction as it donates an electron. Regeneration step also uses 3 ATP in conversion of G3P to RUBP molecules.
A total of 9 ATP and 6 NADPH are utilized in producing 3C G3P molecule, So, to produce 6C sugar molecule 18 ATP AND 12 NADPH are used.
During chemiosmosis synthesis of ATP, 4 protons produce 1 molecule of ATP which could be able to generate 3 molecules of ATP for each pair of NADPH. so, noncyclic photophosphorylation or Z-scheme will be able to produce ATP in the absence of cyclic photophosphorylation.
Thus, 18 ATP and 12 NADPH and noncyclic photophosphorylation can produce ATP molecule in the absence of cyclic photophosphorylation are the correct answer.
Answer:
The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.
Answer:
G₀ phase
Explanation:
Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.

All organisms are made of cells. All cells are similar in composition and metabolic activities. Thus, the correct option is A.
The first theory about cell was proposed by two German biologist Theodor Schleiden and Matthias Schwann in 1839.
The main postulates of this theory are as follow:
1. Cell is the basic structural and functional unit of living organisms.
3. All living organisms are composed of cells.
3. New cells arise from already pre existing cells by division.
Modern cell theory is the new version of same cell theory. It also added that all cells are chemically similar in composition and metabolic activities. Cells contain hereditary materials and energy flow occurs with in cell.

Answer:
It is the bell sign, this can be positive due to nerve involvement or due to an ideopathic question.
The bell sign is positive or negative according to different signs perceived by the dental professional or maxillofacial surgeon.
It is the affection of the seventh cranial nerve, that is to say, of the facial nerve.
Explanation:
The facial nerve is a nerve that is responsible for the sensitivity of the face and the motor skills of the muscles of mime, chewing, swallowing and facial expressions.
The pathognomonic signs are:
facial pain, hyperacusis, decreased ocular tearing, diagusia, and when the patient tries to close the eye it deviates upwards and to the side.
In addition to these signs there is a very characteristic one that is anesthesia or hemifacial paralysis, that is, of the middle of the face.
The positive bell sign usually occurs in patients who have serious automobile accidents.
