Organelles are specialized structures within a cell that serve a specific function. For example, mitochondria supply energy to the cell by generating adenosine triphosphate. Ribosomes are the site for protein synthesis. The nucleus is in charge of all of the activities of the cell.

There are two types of nitrogenous bases: purine and pyrimidine bases. Purine bases have two rings in their structure and consist of adenine and guanine. Pyrimidine bases only have one ring in their structure and consist of thymine and cytosine (DNA) and uracil and cytosine (RNA). Therefore, the correct answer is B since thymine is a pyrimidine.

Enzymes are substrate-specific. Most enzymes catalyze only one biochemical reaction. Their active sites are specific for a certain type of substrate and do not bind to other substrates and catalyze other reactions.

There are four major types of carbohydrates: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides (mono- means one) are made up of one sugar molecule, while disaccharides (di- means two) are made up of two sugar molecules. Oligosaccharides (oligo- means few) are usually less than a dozen sugar molecules, while polysaccharides (poly-means many) are usually more than a dozen sugar molecules.

Pentasaccharides are not a type of carbohydrate.

Liquids have no definite shape, but they do have a definite volume. While the particles of liquids move more freely than those in solids, they do maintain a definite volume.

Of these orbitals, the last to fill is 6s.

Orbitals fill in the following order: 1s, 25, 2p. 35, 3p, 4s, 3d, 4p, 55, 4d, 5p. 6s, 4f, 5d, 6p. 7s, 5f, 6d, and 7p. The number is the orbital number, and the letter is the sublevel identification. Sublevels has one orbital and can hold a maximum of two electrons. Sublevel p has three orbitals and can hold a maximum of six electrons. Sublevel d has five orbitals and can hold a maximum of 10 electrons, Sublevel f has seven orbitals and can hold a maximum of 14 electrons.

The gastrocnemius vein is found in the calf. The femoral vein is found in the proximal anterior thighs/pelvis.

Since the gastrocnemius vein is found below the femoral vein it is distal or inferior to the femoral vessel.

Homeostatic mechanisms are involuntary actions by organs, glands, tissues and cells to maintain balance within the body. If a function is disrupted the body will readjust in an attempt to maintain balance. During periods of starvation the body will break down glucose reserves in order to maintain normal glucose levels.

There are three types of proteins: fibrous, membrane, and globular. Fibrous or structural proteins consist of collagen, elastin, and keratin. Membrane proteins are interactive and anchored to a membrane. Globular proteins consist of functional proteins like enzymes, hemoglobin, and insulin.

Therefore unsaturated is the correct answer.

Enzymes act as catalysts for biochemical reactions. A catalyst is not consumed in a reaction, but rather lowers the activation energy for that reaction. The potential energy of the substrate and the product remain the same, but the activation energy-the energy needed to make the reaction progress can be lowered with the help of an enzyme.
