Answer:
Nucleic acid types differ in the structure of the sugar in their nucleotides–DNA contains 2'-deoxyribose while RNA contains ribose (where the only difference is the presence of a hydroxyl group).

The pith is the center of a stem and can store food.
Pith is the tissue that is located in the center of the stems of vascular plants. Pith is made up of soft spongy distinctive parenchyma cells which are large but have thin walls. The major function of pith is to convey nutrients to every part of the plant and to store nutrients in its cells.
The options are incorrect. The correct question with options is:
Which of the following statements is true concerning catabolic pathways?
A. They combine molecules into more energy-rich molecules
B. They supply energy, primarily in the form of ATP, for the cell's work
C. They are endergonic
D. They are spontaneous and do not need enzyme catalysis
E. They build up complex molecules such as protein from simpler compounds
Answer:
B. They supply energy, primarily in the form of ATP, for the cell's work
Explanation:
Catabolic pathways are the metabolic pathways that breakdown the complex molecules into simpler substances. The chemical reactions of catabolic pathways are mostly exergonic with a negative value of free energy change.
The released energy is stored in the form of ATP molecules. The energy-releasing reactions of catabolic pathways supply the cells with ATP molecules to perform the functions. For instance, breakdown of glucose into CO2 and H2O during aerobic cellular respiration is a catabolic process and forms as many as 32 ATP molecules.
