Answer:
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

Satellites helping scientists map the earth doesn't really have an example of science. It just says that Satellites help scientists, and satellites are technology.
Robotic machines are also technology. Robots assisting doctors in surgery is technology helping people not science influencing technology.
So A and B would be the answers.
Hope this helps :)
