To identify the molecule that accepts CO₂ , Calvin and Benson manipulated the carbonfixation cycle by either cutting off CO₂ or
Alexxandr [17]

To identify the molecule that accepts CO_{2}, Calvin and Benson manipulated the carbon-fixation cycle by either cutting off CO_{2} or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. The CO_{2} acceptor concentration would increase when the CO_{2} 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 CO_{2} or removing light from cultures of photosynthetic algae in order to find the molecule that takes CO_{2}. Following the alteration, they evaluated the concentrations of several metabolites.

How is a frog disected?
Stella [2.4K]
<span>Lay the frog on its back, spread out its limbs, and pin them to the tray. Use forceps to lift the skin between the hind legs and make a small incision with a scalpel. Continue the cut up the center of the frog's body with scissors, being careful to cut through the skin only. Use forceps to hold the skin away from the muscle while you cut, if necessary. Make horizontal incisions just above the legs and just below the arms, then fold the resulting flaps back and pin them. (You may need to use a scalpel to help separate the skin from the muscle underneath as you fold it back.)Repeat the incisions as before, this time cutting through the muscle layer to a point just below the arms. Lift the muscle with the forceps to prevent cutting the organs underneath.When you reach the area just below the arms, turn your scissors and make horizontal cuts through the hard sternum. Repeat the horizontal cuts just above the arms, and then remove the bony strips entirely. Pin the remaining muscle flaps back, just as with the skin.<span>Look into the body cavity. The yellow finger-like projections on the sides are the fat bodies. It may be necessary to remove some of these in order to see the organs clearly. Likewise, a female specimen may have well-developed eggs filling the body cavity and obscuring the organs. Remove them as necessary.</span></span>

What would happen without any decomposers in the cycle​
VikaD [51]

decomposers break down dead things and waste, so I would say that dead animals would not go back into the ground as fast and the nutrients would not go back into the cycle
