Answer : (A) "It reflects waves off of objects, measuring the difference of the waves it sends and receives".
Explanation :
In Doppler radar system, radio waves emitted from an antenna. It gives information about the motion of targets and their position.
Phase change between a transmitted wave and received echo is calculated using Doppler radar system.
It also gives radial velocity i.e. velocity in the direction of radar. If the phase shift is positive this means the motion is toward the radar and if the phase is negative this implies the motion is away from the radar.
So, the correct option is (A) "It reflects waves off of objects, measuring the difference of the waves it sends and receives".

Carbon fixation occurs in the second stage of photosynthesis, during the light-independent reactions of the Calvin cycle. In the first step of this cycle, the enzyme Rubisco adds CO2 to the energy-rich compound ribulose 1,5-bisphosphate, ultimately producing two molecules of 3-phosphoglycerate. In a culture of green alga that is carrying out photosynthesis in the presence of CO2 in the laboratory, what would happen to the levels of ribulose 1,5-bisphosphate and 3-phosphoglycerate in the minutes after the lights were turned off and the cultures were plunged into darkness
Ribulose 1,5-biphosphate will be depleted while 3-phosphoglycerate will accumulate.
Carbon fixationThe first step of the carbon fixation during which Rubisco adds CO2 to Ribulose 1,5-biphosphate to produce 2 molecules of 3-phosphoglycerate requires energy molecules from the light reaction.
In the subsequent steps, Ribulose 1,5-biphosphate is regenerated in a step that requires energy molecules from the light reaction.
Thus, in the first few minutes of turning off the light, the available energy molecule from the light reaction will be used up to produce 3-phosphoglycerate. However, the regeneration of Ribulose 1,5-biphosphate will become impossible.

How can we see the object?Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.
The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.
These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.
