The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.
i hope this helped, have a nice day! (o:
Answer:
<u><em>BRIEF EXPLANATION</em></u>
Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.
Explanation:
<em><u>MAIN ANSWER TO THE QUESTION.</u></em>
Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.
Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.
Energy is defined as the ability to do work
