Given that there are over 100 million residential addresses in the United States, which of the following best describes a flaw of this survey as it is described?

A. There were not enough age groups to show a trend based on age.

B. The addresses were chosen randomly rather than strategically

C. The distribution of ages in the sample did not reflect the actual population

D. Each response represents only one person per address

Answer Explanation:

While the random selection and large number of surveys sent out were a good start, to truly study the relationship between age and screen usage, it would have been better to have a few more age groups or just a direct age value from each participant rather than four large categories. As far as whether the age distribution accurately reflected the population, we don't have enough information to say if that was a problem or not. Also, the fact that each response is from just one person at the address is not a flaw but a reasonable way to get a good variety of responses

Therefore, the Correct Answer is A.

Q #1: 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.
Q #2: Which of the following anatomical terms is NOT part of the knee?

A. Medial collateral ligament

B. Patella

C. Lateral malleolus

D. Lateral meniscus

Answer Explanation

The term "lateral malleolus" refers to the bony prominence on the outer side of the ankle.

It is part of the ankle joint, not the knee joint. The other options, such as the medial collateral ligament, patella, and lateral meniscus, are all associated with the knee joint.
Q #3: Which section of the digestive system is responsible for receiving chyme and further digesting it?

A. The large intestine

B. The duodenum

C. The jejunum

D. The gallbladder

Answer Explanation

The duodenum is the first section of the small intestine. It receives partially digested food (also called chyme) from the stomach, further digesting it with the help of enzymes released by the gall bladder. Then, the food enters into the jejunum, then the ileum. The large Intestine's main function is the reabsorption of water into the body to form solid waste. It also allows for the absorption of vitamin K produced by microbes living inside the large intestine.
