Answer:
The correct answer is option D. Light and some other factors are necessary for chlorophyll production
Explanation:
By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.
Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.

Answer: It can create unique landforms, such as wave-cut cliffs, sea arches, and sea stacks. Deposits by waves include beaches. They may shift along the shoreline due to longshore drift. Other wave deposits are spits, sand bars, and barrier islands.
Explanation:
Together with the Moon, Venus and Mars are the planets nearest to the Earth. All of these celestial bodies are continuously held captive to the sun by the effect of gravity; the bodies are continually forced to orbit the sun as the central body in elliptical orbits. Mars
Mars Close Approach to Earth
Simply go outside and look up and, depending on your local weather and lighting conditions, you should be able to see Mars. That is the point in Mars' orbit when it comes closest to Earth, this time at about 38.6 million miles (62.07 million kilometers) from our planet. 24.8 million miles
Venus is closest to Earth at its inferior conjunction. The smallest distance this can be today is just under 24.8 million miles (40 million km). Their orbits rarely make this happen, but there is such a close approach in January 2022. Also, The Moon
A huge system of stars is called a galaxy. The Moon is the closest celestial body to our Earth. Earth is the third nearest planet to the Sun. Planets do not have their own heat and light.
