Answer:
How energy is produced and managed from solar cells?
Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun's core and fuse to create a helium atom. This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy
Explanation:
All based on research.
Answer:
The energy trapped in fossil fuels came from the energy plants converted during photosynthesis. This trapped energy is. chemical ... are using energy for
Explanation:
You need to draw a food chain starting with something small like bacteria and and getting back around the loop to bacteria again( explaining what the the previous organism does to the next for example it eats it). Then you need to underline the organisms/animals. Then write in bold the way it got the energy from the previous one( for example if it eats it )
Answer:
(2) low power: 100 small pollen grains
high power: 25 large pollen grains
Explanation:
Compound light microscopes are devices used to greatly magnify objects. They have several objective lenses, a low-power lens magnifies 10 times (10X) the objects, and the high-power lens magnifies them 40 times (40X).
For that reason, when observing the pollen grains with the high-power lens the student will see them bigger than with the low-power lens. However, the field of view (the visible area through a lens) is reduced when a higher power lens is used, so fewer pollen grains will be seen.
The answer therefore is the option of higher number of pollen grains of small size for the low-power lens, and lower number of pollen grains of larger size for the high-power lens.
