How many people would be needed to stain a deck in just one day if 4 people can do it in 2 days?
Correct Answer
A. 8
Explanation
If 4 people can stain a deck in 2 days, it means that the work can be divided equally among the 4 people and each person takes 2 days to complete their portion. Therefore, if we want to complete the work in just one day, we need to double the number of people. So, 4 people multiplied by 2 equals 8 people. Hence, 8 people would be needed to stain a deck in just one day.

How long will it take you to travel 250 miles at a speed of 50 mph to get to the town?
Correct Answer
B. 5 hours
Explanation
At a speed of 50 mph, it would take 5 hours to travel 250 miles. This can be calculated by dividing the distance (250 miles) by the speed (50 mph), which gives the time taken to cover the distance.
5.
Which of the following describes the flow of oxygenated blood from the heart to the body?
Correct Answer
A. Systemic circulation
Explanation
Systemic circulation describes the flow of oxygenated blood from the heart to the body. This process involves the pumping of oxygenated blood from the left ventricle of the heart into the aorta, which then branches out into smaller arteries that deliver the oxygenated blood to the various organs and tissues throughout the body. After delivering oxygen to the body, the deoxygenated blood returns to the heart through the veins and enters the right atrium, starting the cycle again.
6.
In which of the following structures of the mammalian digestive system is it most likely that nutrients will be absorbed?
Correct Answer
A. Duodenum
Explanation
The duodenum is the first and shortest segment of the small intestine, located immediately after the stomach. It is in the duodenum where most of the chemical digestion of food takes place, and it is also the primary site for nutrient absorption. The walls of the duodenum are lined with finger-like projections called villi, which increase the surface area available for absorption. These villi contain specialized cells that transport nutrients, such as carbohydrates, proteins, and fats, into the bloodstream for distribution to the rest of the body. Therefore, it is most likely that nutrients will be absorbed in the duodenum.
7.
Which of the following is most likely to be happening in populations that are supposedly in a zero-growth phase?
Correct Answer
C. The death and emigration rates equal the birth and immigration rates.
Explanation
In a zero-growth phase, the population remains stable as the number of deaths and emigration is equal to the number of births and immigration. This means that the population is neither increasing nor decreasing. If the death and emigration rates are greater than the birth and immigration rates, the population would be declining. Conversely, if the birth and immigration rates are greater than the death and emigration rates, the population would be increasing. Therefore, in a zero-growth phase, the death and emigration rates must equal the birth and immigration rates.
8.
Which of the following will be brought on by an aortic dissection?
Correct Answer
D. Oxygenated blood would not be transported to the body’s cells.
Explanation
An aortic dissection is a serious condition where there is a tear in the inner layer of the aorta, the largest artery in the body. This tear can lead to the leakage of blood into the middle layer of the aorta, causing a separation of the layers. As a result, the flow of blood through the aorta becomes disrupted. Since the aorta is responsible for carrying oxygenated blood from the heart to the body's cells, an aortic dissection can impede the transport of oxygenated blood to the body's cells, leading to tissue damage and potentially organ failure.
