During fixation, the initial phase of the Calvin cycle's light-independent reactions, CO2 is converted from an inorganic to an organic compound. In the following phase, ATP and NADPH molecules provide energy and reducing power to transform 3-PGA into G3P, while ATP and NADPH are converted back to ADP and NADP+ respectively.

Answer:
Ethylene. (Ans. D)
Explanation:
Ethylene controls the aging and ripening processes in plants. While many fruits and vegetables generate small amounts of ethylene, climacteric fruits like bananas produce larger quantities. This ethylene release accelerates respiration, triggers more ethylene production, and causes changes in color and flavor.
Therefore, when transporting green bananas over long distances to stores, the ethylene gas should be removed from their surrounding environment.
Spiders are categorized as part of the arachnid family.
Arachnids exhibit several characteristics:
They possess two distinct body segments.
Unlike insects that have six legs, they have eight.
They lack wings.
These features set them apart from insects.
Antonio is questioning the validity of the claim that the differences in spiders arose because they were the first to evolve.
This is due to the fact that the evolution of one species happens independently from another.
Answer:
Ribosomes, Cell membrane
Explanation:
Ribosomes serve as the sites where proteins are synthesized. Therefore, they are referred to as the protein production factories of a cell. Since enzymes are a type of protein, their synthesis occurs within ribosomes.
The cell membrane functions as the boundary that surrounds the cell or separates it from its environment.
To exit the cell and enter the external environment, an enzyme must navigate through both the ribosomes and the cell membrane.
The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
