No. Because plant roots do not have access to direct sunlight. And sunlight is needed for photosynthesis.

This is high power. The lowest setting on a microscope is 40x. Each power is going by being multiplied by 10.
The study of earthquakes is seismology. Scientists (seismologists) use instruments to record the strength of earthquakes in an area. The instrument that is used to measure seismic waves is called seismograph. <span>It records the shaking of the Earth. </span>The size of an earthquake is measured with its magnitude and intensity.
The answer should be C, It diffuses from the alveoli into the blood.
Alveoli, also called the air sac, is the place where the oxygen we breathed in is exchanged with carbon dioxide that our body produces. Oxygen is passed into the blood in the capillaries through the process of diffusion, while carbon dioxide is diffused from the blood back to the alveoli, so that we can exhale the carbon dioxide after that.
Both a and b are not right because when we breathe in, the oxygen travels from the trachea to the bronchi, to the bronchiole, and to the alveoli, instead of directly into blood vessels like arteries, capillaries, or veins. d is also not right because the direction is wrong.
Therefore, your answer should be C.
