The diagram shows a nucleic acid in the shape of a double helix.
A D N A strand in the shape of a double-helix is shown.

Which sugar is present in the nucleic acid that is represented in the diagram?
phosphate
uracil
deoxyribose
ribose

deoxyribose

Explanation: From the information provided, (though the diagram is not shown), the structure is a DNA double helix. A DNA contains deoxyribose sugar thus the name deoxyribonucleic acid. RNAs contains ribose sugar thus the name ribonucleic acid. A deoxyribose is a pentose (a 5- carbon sugar) which lacks one oxygen atom at position two of its carbon skeleton, hence the name deoxy - ribose. It's usually written chemically as 2- deoxyribose.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
