The best answer is (1)
Fossil fuels are commercially available as an energy source.
They are very easy to find. More and more extractions of fossil fuels is going on everyday. With advancement in science and technology, the refineries and extraction procedures have improved a lot. This makes their availability even better.
Fossil fuels are also easily combustible. Most combustion engines need to be powered with little amount of fuel to produce large amount of energy. Very large amounts of electricity can be generated from fossil fuels.
Answer:
What do they look like?
Glaciers look like solid blocks of ice.
What climate do they exist in?
Regions that have high snowfall in winter and cool temperatures in summer.
Where can you find them?
Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.
What do you think we can learn from glaciers?
Glaciers preserve bits of atmosphere from thousands of years ago in these tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages. Scientists are also finding that glaciers reveal clues about global warming.
(The last question is unclear to me, so I'm going to take a guess as to what you meant)
Why is sea ice so important?
Arctic sea ice keeps the polar regions cool and helps moderate global climate.
I hope this helps!! :3
Answer:
Molecules carrying amino acids are positioned in the ribosome’s two docking sites.
Explanation:
A ribosome is a molecular machine that coordinates protein assembly.
- A ribosome brings together correctly the mRNA, which needs to be translated, and the tRNA, which assists in the translation process, to come together correctly.
- During translation, tRNA molecules carrying amino acids are positioned in the ribosome’s two docking sites.
- After the translation, the tRNA disassemble and is being reused many times.
George Mendel chose to use purebred plants in his experiments because they have a variety of traits.
It is not c or d. I think it is a.
