Most organisms either directly or indirectly use energy from the sun to survive, but not all of them. Plants and some microbes use the energy from the sun to perform photosynthesis.
Answer:
Cell Theory
✓ All living things are made up of cells
✓ Cells come from other cells
✓ Cells are the smallest living part of a living thing
✓ Cell function to keep the cell, and the organism, alive
Answer:
Explanation:
Law of conservation of energy states that energy can neither be created nor destroyed. Thus, in relation to the question, as the object slides down the ramp, the kinetic energy should increase at the same rate the potential energy is reducing in such a way that the kinetic energy of the object at the bottom of the ramp should be equal to the potential energy of the object at the top of the ramp (since the energy was been "transferred" as the object moved). However, this situation only occurs, as explained, in the absence of friction. <u>In the presence of friction, some of the energy is used to overcome friction as the object moves down the ramp and as such there is an energy loss due to friction in the process which makes the kinetic energy at the bottom of the ramp not equal to the potential energy at the top. This also does not violate the law of conservation of energy since no energy was destroyed in the process (as all the energy involved can be accounted for)</u>.
Some of the challenges that scientists might face in space when growing plants would be the fact that plants must have carbon dioxide to carry out their process, which is why they are grown in special chambers. It is true that the astronauts would put off some carbon dioxide, but perhaps not enough. You would also be trying to grow plants in a zero gravity environment, which they aren't accustomed to.
The astronauts would have to be able to provide an extremely large amount of food in order to meet their nutrition needs. There would have to be enough room to grow an adequate amount of food aboard the ship. The plants would also need to be able to produce more than one crop per growing.
If scientists could genetically modify plants to help them grow better in space, they would need to make them able to thrive in a low gravity setting. They would also need to try and engineer them to need less water to survive. They would need to be strong enough to survive the lift off when going into space. The plants would also need to be able to regenerate and produce vast quantities of food.
