Both light-dependent and light-independed reactions of photosynthesis are similar in a way because they both require chemical energy to proceed.
Photosynthesis occurs in two successive stages. These stages are:
1) The light-dependent reactions
2) The light-independent reactions
The light dependent reactions absorb energy from sunlight and converts it into chemical energy. The chemical energy produced (ATP) by the light-dependent reactions is used by the light-independent reactions for it to function properly. The remaining chemical energy (ADP) in the light-independent reactions is returned to the light-dependent reactions to obtain more energized electrons.
Answer: oxygen is present; electron transport chain is used
Explanation:
weight=mass*gravitational accelaration
we know the weight and the gravitational acceleration
400N=m*10m/s^2
m=400N/10m/2^2
m=40kg
Arrows coming from one organism and pointing to another shows the flow of energy.
Plant------>Mouse
The mouse is getting energy from the plant.
Answer:
The correct answer will be option-Cells can generate from nonliving matter.
Explanation:
Rudolf Virchow is known for modifying the cell theory proposed by the Schleiden and Schwann in 1839. He added to the existed theory and suggested that all living cell come from the pre-existed cells.
But this hypothesis was disproved after the Miller and Urey performed an experiment in 1953 and demonstrated that cells were originated from the non-living matter present in the atmosphere during primordial time.
This fact disproved the hypothesis of Virchow ans thus is the correct answer.
