Why do fish have gills​
Marta_Voda [28]

Answer: Like us, fish also need to take in oxygen and expel carbon dioxide in order to survive. But instead of lungs, they use gills. ... As the fish opens its mouth, water runs over the gills, and blood in the capillaries picks up oxygen that's dissolved in the water.

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.

Marat540 [252]

Answer:

Light energy, Water, and Carbon Dioxide/Chlorophyll

Explanation:

Photosynthesis uses 12 water molecules, 6 Carbin Dioxide molecules and light energy so it can produce one glucose, six water and oxygen molecules. This can be expressed and represented by 12H2O + 6CO2 + light energy = C6H12O6 + 6H2O + 6O2

Vital to remember that the produced oxygen is from the original water molecules and not the carbon dioxide.
