To identify the molecule that accepts 
, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The acceptor concentration would increase when the is cut off, but decrease when the light is cut off.
The correct option is d.
The process through which living things absorb inorganic carbon from the atmosphere and transform it into organic molecules is known as carbon fixation. These substances are employed as chemical energy storage. For life to continue, it is a necessary process.
Calvin and Benson disrupted the carbon-fixation cycle by either removing or removing light from cultures of photosynthetic algae in order to find the molecule that takes . Following the alteration, they evaluated the concentrations of several metabolites.

Which statements describe why organisms are classified? Check all that apply.
1. Classification shows how closely related organisms are to each other.
2. Classification makes organisms easier to study.
3. Classification allows for better identification of new organisms.
The grouping system makes it easier for scientists to study certain groups of organisms.
Answer:
b. Synergistic dominance
Explanation:
The stabilizing muscles will always be <u>synergistic</u>, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.
In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.
