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 of the following are examples of homeostatic mechanisms?

A. Increasing heart rate when blood pressure is low, Consuming excess calories to gain weight

B. Lifting weights to increase muscle mass

C. Shivering when the body temperature falls

D. Shivering when the body temperature falls, Secreting insulin to decrease blood sugar concentration, Increasing heart rate when blood pressure is low

Answer Explanation

Homeostatic mechanisms are involuntary actions by organs, glands, tissues and cells to maintain balance within the body. For example, if a person becomes dehydrated, the kidneys will retain fluid by decreasing urine output.

Consuming excess calories and lifting weights are not involuntary actions, nor do they maintain the body in its baseline state. Rather, they are actions specifically taken to move the body away from its baseline.
Q #2: Which is NOT a type of protein?

A. Fibrous

B. Membrane

C. Globular

D. Unsaturated

Answer Explanation

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.
Q #3: Which of the following does NOT obey the law of independent assortment?

A. Two genes next to each other on a chromosome

B. Two genes on opposite ends of a chromosome

C. Flower color and height in snapdragons

D. Seed color and flower color in peas

Answer Explanation

Two genes next to each other (or within a specified close distance) are said to be linked. Linked genes do not follow the law of Independent assortment because they are too close together to be segregated from each other in meiosis.
