I wrote a paragraph summing the importance of Carbon a while back, see if it helps find your answer. :)
Carbon is an element on the periodic table with the symbol C, and the atomic number 6. There are many reasons that carbon is vital to life on earth, not only to humans but to plants as well. First of all, humans are made of eighteen percent carbon. It is not only found in humans, it is also found in every organism currently known, including plants in a technological way. To plants, carbon flows inside of their cells. They need it to create glucose which then works as food. To humans, it's used in many science sets. It is used in a vast array of compounds including gasoline. Gasoline is what keeps motors around the world running, and it's made up of hydrocarbons with at least 5 carbon atoms each. It also aids the greenhouse effect, keeping the earth warm and habitable by human beings.
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
Explanation:
Before a chemical reaction, the elements and compounds which are about to take part in the reaction are known as reactants.
And, when the chemical reaction takes place between the given elements and compounds then they change into products.
For example, we take sodium and chlorine elements and before any chemical reaction they are the reactants.
But when a chemical reaction takes place between sodium and chlorine then it results into the formation of sodium chloride which is the product.
Answer:
Students who take a PE class and who will be eating sugary snacks before PE.
Explanation:
The control variable (or control group) is an experimental element which is constant or unchanged throughout the course of the experiment.
The option "students who take PE class and who will be eating sugary snacks before PE" will remain unchanged and constant because the whole point of the experiment is to see the effects on students performance in PE after eating sugary snacks.
Hope this helps :)
