A. It forms a part of the upper atmosphere known as the ozone layer.
Answer:
The water molecules in ice are considerably far apart as compared to cold water of 4 degrees centigrade and below. This, therefore, makes ice less dense than water at these temperatures (because they are fewer water molecules in ice per unit volume). This is why ice floats on cold water below 4 degrees centigrade. Ice, being a bad conductor of heat, shields the water below an ice sheet from excessive heat loss to the atmosphere. This is why water remains liquid below an ice sheet protecting the marine life below from complete freezing.
What is the question you are asking tho?
Answer:
This question is incomplete
Explanation:
This question is incomplete but the keys words in the question provides an idea of what the completed question is.
There are two types of nucleic acid; ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).
They are both made up of ribose/pentose sugar, nitrogenous base and phosphate group.
The ribose sugar of the DNA is one oxygen less than the ribose sugar of the RNA hence the reason for the name "deoxyribose".
There are five nitrogenous bases namely; adenine, thymine, guanine, cytosine and uracil. They both contain adenine, guanine and cytosine; however, the DNA contains thymine while the RNA contains uracil. Of the five bases, adenine and guanine are the purines (have a double ring structure) while the rest are pyrimidines (have a single ring structure).
The phosphate group here is negatively charged
Answer:
inputs: carbon dioxide, water
outputs: sugar, oxygen
Explanation:
Here is the equation for photosynthesis:
CO2 + H2O ----sunlight energy---> C6H12O6 (glucose/sugar) + O2
