Answer:
Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are composed of nucleotides. A nucleotide is composed of three smaller molecules; a five-carbon, a phosphate group, and a nitrogenous base.
A DNA nucleotide contains the five-carbon sugar deoxyribose, a phosphate group, and one of four nitrogenous bases; adenine (A), guanine (G), cytosine (C), and thymine (T).
RNA contains the five-carbon sugar ribose, a phosphate group, and one of four nitrogenous bases; adenine (A), guanine (G), cytosine (C), and uracil (U). Uracil takes the place of thymine (T).
Both thymine and uracil pair with adenine.
So DNA and RNA nucleotides differ according to which five-carbon sugar is present, and whether the nitrogenous base thymine or uracil is present. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil.
Explanation:
Greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range.
Answer:
Explanation:
independent= pH as you will change the pH in order to test your hypothesis and see if it's true
dependent= how amylase works-needs to be measured so you can see how easily it does it function depending on the pH (dependent on the independent variable)
