Every child in a certain family has been diagnosed with autism spectrum disorder (ASD). Based on this evidence, what possible conclusion can be drawn about ASD?

A. ASD may be lethal.

B. ASD may be genetic.

C. ASD is related to traditional nuclear family structures,

D. No conclusion can be drawn based on this evidence.

Answer Explanation:

The evidence says that every child in a certain family has been diagnosed with autism spectrum disorder (ASD). All of these children have genetic commonalities. Therefore, ASD may be genetic.

The evidence does not mention whether the children died from ASD. Therefore, no conclusion can be drawn that ASD may be lethal. Furthermore, the sample size of the evidence is much too small to suggest that ASD is related to traditional nuclear family structures.

Therefore, the Correct Answer is B.

Q #1: Which is NOT a major type of carbohydrate?

A. Monosaccharides

B. Disaccharides

C. Pentasaccharides

D. Polysaccharides

Answer Explanation

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.
Q #2: Which of the following statements concerning the states of matter is NOT true?

A. Plasmas are high-temperature collections of ions and free electrons.

B. Solids are the least compressible due to the more rigid positions of the particles.

C. Gases have no definite volume and expand to fill their containers

D. Liquids have no definite shape and no definite volume.

Answer Explanation

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.
Q #3: Homeostasis is defined as:

A. Ability of human beings to keep body weight within normal limits

B. Maintenance of a constant external temperature inside a room

C. Ingestion of enough food to keep hunger pains from developing

D. Tendency of the body to maintain a stable environment

Answer Explanation

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.
