Question 3

There are 10 cloned horses, born on the same day, with identical chromosomes.They are each subjected to the same physical training regimen, but given daily injections of different concentrations of a particular vitamin.They all run the same race.You set up a graph to explore a relationship between race finish time and vitamin dose.
Which type of graph is best to explore a relationship between race finish time and vitamin dose?

Accepted Answer

A scatter plot is the best choice for exploring the relationship between race finish time and vitamin dose because it allows for the visualization of individual data points and any trends or patterns that may emerge. A bar graph would not be appropriate because it is designed for comparing categorical data and does not show individual data points. A line graph would also not be the best choice because it implies a continuous relationship between the two variables, but the relationship between race finish time and vitamin dose may not be continuous.

Question 7

You conduct an experiment on twenty 18-year-old male subjects to see how various intensities of exercise influence heart rate.Which of the following is/are considered a dependent variable?

Accepted Answer

The dependent variable is what is being measured or observed in the experiment. In this case, it is the heart rate of the subjects, which is being affected by the various intensities of exercise. The age and sex of the subjects are independent variables, since they have been predetermined and are not being changed or tested in the experiment. The intensity of exercise is also an independent variable, since it is being manipulated by the researcher to see its effect on heart rate.

Question 8

Adaptive significance is an important concept in physiology because it describes the

Accepted Answer

The concept of adaptive significance in physiology refers to the physiological functions that promote an organism's survival. It is concerned with how traits have evolved over time to better serve an organism in its environment.

Question 10

You want to display data on the finish times of the 10 fastest race horses in a single race at the Kentucky Derby.
Which type of graph would be best to display this information?

Accepted Answer

A bar graph is best for comparing the finish times of individual horses in a single race, as it clearly shows the differences in times among the horses.

Question 11

A horse runs 10 races, each a mile long, during a 6-month period, and you are interested in determining if the horse's race time changes with experience.You set up a graph to display the race finish times of this horse.
What would the labels be for the graph axes?

Accepted Answer

The answer of A horse runs 10 races, each a...

Question 12

Which of the following systems does NOT exchange material with the internal and external environments?

Accepted Answer

The circulatory system primarily transports materials within the body and does not directly exchange materials with the external environment.

Question 16

Individuals with Type I diabetes do not make enough insulin.Which of the following would be a mechanistic explanation of how insulin is used by the body?

Accepted Answer

Insulin binds to its receptor which triggers the movement of glucose transporters to the cell membrane, allowing glucose to enter the cells and be used for energy. This is the fundamental mechanism by which insulin regulates glucose homeostasis in the body.

Question 17

You conduct an experiment on twenty 18-year-old male subjects to see how various intensities of exercise influence heart rate.Which of the following is/are considered an independent variable?

Accepted Answer

The independent variable is the variable that is manipulated or changed by the researcher. In this experiment, the intensity of exercise is being changed by the researcher, making it the independent variable. Age and sex are not being manipulated, and heart rate is the dependent variable that is being measured in response to the different intensities of exercise.

Question 18

The human environment is terrestrial, dry, and highly variable.However, our bodies expend enormous amounts of energy maintaining a constant internal environment.Studying why our bodies do this is what kind of scientific endeavor?

Accepted Answer

The study of why our bodies maintain a constant internal environment despite the variability of the external environment is a teleological endeavor, as it is focused on understanding the purpose or function of a biological process or system.

Question 20

A horse runs 10 races, each a mile long, during a 6-month period, and you are interested in determining if the horse's race time changes with experience.You set up a graph to display the race finish times of this horse.
Which type of graph would be best to display the race finish times of this horse?

Accepted Answer

A line graph would be best to display the race finish times of this horse since it allows for a continuous representation of the data over time, and it would be easy to see any changes or trends in the horse's race times as it gains experience. A scatter plot would not be appropriate since there is only one variable being measured (race time) and it does not relate to another variable. A bar graph could be used to display the results, but it would not be as effective as a line graph because it does not provide a continuous representation of the data over time.
