1. how did scientists discover that all living things are made of cells? 2. how did pasteur’s experiment with the flasks disprove the idea that living things could just appear or come from nonliving things like water and air? 3. why are nutrients needed for living things? describe the difference between living and nonliving things.

The answer for the first question os based on cell theory by 3 well-known scientists

The answer for the third question is living things require energy and it will be derived from nutrient.the differentiation is phloem and large intestine where they'll process and absorbed into bosy by vilus

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

D. h2o + h2o > h3o + oh- confirmed.
