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.

Responsible for releasing adrenaline, if there are answer choices we’d need them in order to reply
if they did something wrong while doing it: for example, if they were supposed to make your future baby's hair pink but instead it made your baby be bald forever, this will be very harmful to the communities. they will lose a lot of money and receive lots of hate.
hope this helps. :)
stay safe, happy, and healthy! have a great day.
Answer:
Species that are broadly distributed are less likely to go extinct than those that occupy a small area or whose habitat is disjointed.
