                            Pulse Rates 
A student heard a sports news report that several fans who were wearing smartwatches received irregular heart rate warnings as they were viewing the last few minutes of a football playoff game. The alert stated that they had an irregular increase in heart rate during a time in which they were inactive. The student decided to conduct his own experiment in order to determine if watching an exciting sporting event would increase the pulse rates of viewers. He asked six of his friends to watch a championship game and had them take their pulse rates during the first quarter of the game and at the end of the game. The results are recorded in the data table below.

During a lab experiment a student took his resting pulse rate, counting 23 beats in 20 seconds. The student then exercised for several minutes. The student’s pulse was taken immediately after the exercise, and then every minute for 6 minutes. The graph below shows changes in the pulse rate after the exercise was completed.

What was the student’s resting pulse rate in beats per minute?

The diagram below represents a lab setup. The artificial cell (dialysis tube) contains a starch solution and the beaker contains a solution of starch indicator and water. The setup is left undisturbed for twenty minutes.

Identify one molecule, present in this setup, that will be able to pass through the dialysis tubing.

The process of transferring energy during respiration occurs in a series of steps. This prevents too much heat from being released at one time. Maintaining an appropriate temperature is beneficial to an organism because:

enzymes need a proper range of temperatures to catalyze vital reactions

cellular waste products can only be excreted in cooler temperatures

hormones can only produce antibodies if temperatures are not excessive

nutrients diffuse faster into cells when temperatures are lower

Blood sugar levels increase after a meal and eventually return to normal. This is represented in the diagram below.

This constant correcting of blood sugar levels within the body is accomplished by

a feedback mechanism

an immune response

an allergic reaction

manipulating a gene

Will individuals who have taken the vaccine be protected against future tetanus infections? Support your answer.

Although the digestive system is primarily responsible for the breakdown of food, this process can be disrupted if the circulatory system malfunctions. The best explanation for this disruption is that:

human body systems interact with each other to perform life functions

the circulatory system is the control center of the body

the digestive system and the circulatory system have many organs in common

the circulatory system is responsible for the coordination of life functions, including the breakdown of food

Which two body systems provide humans with the raw materials necessary for their cells to release energy?

muscular and skeletal

endocrine and nervous

digestive and respiratory

reproductive and circulatory

The diagram below illustrates the release of chemical A from a human cell in response to a specific stimulus.

Which cell structure plays a direct role in the release of this chemical from the cell?

nucleus

ribosome

chloroplast

cell membrane

The diagram provides information about some of the digestive enzymes produced by the human pancreas.

Another important molecule not shown in the diagram is also produced by the pancreas. It functions to decrease glucose levels in the blood. This molecule is:

progesterone

insulin

testosterone

ATP

Antibodies produced against one pathogen infecting the human body may not work against a different pathogen because antibodies are:

only produced once in the body so they can’t work on any other infection

unable to produce effective antibiotics against the infection

made of DNA the second pathogen doesn’t contain

specific for the shape of the proteins present on a particular pathogen

State whether the new drug used without the chemotherapy drug would enable the immune system to successfully attack the cancer cells. Support your answer.

Explain the role of white blood cells in the process of killing cancer cells.

It may be harmful when people compete to see who can hold their breath the longest under water. Without oxygen, brain cells:

cannot make enough ATP

have too few mitochondria

make too many enzymes

have too much water

Which statement is an example of a feedback mechanism in humans?

An increase in the level of blood sugar results in the pancreas increasing the amount of insulin it secretes.

Increased exposure to pathogenic bacteria results in an increase in the number of red blood cells produced.

An increase in exercise results in a decrease in the rate of respiration.

Increased muscle activity results in a decrease in heart rate.

Many disorders are due to the inability of an individual to break down a particular chemical. Sometimes these disorders can be treated by giving the affected individual the appropriate:

enzymes

antigens

chromosomes

organelles

The student stated that data from his experiment supported his claim that pulse rate increases when watching an exciting sporting event.

State an argument for why someone might not accept his claim.

Changes in external temperatures often result in a person either sweating or shivering, as represented in the diagram below.

These responses are one way:

to counteract feedback mechanisms that would otherwise be beneficial

to make the body release insulin to control blood circulation

the body is able to maintain dynamic equilibrium

skin and muscle cells are able to disrupt homeostasis

Human cells have many molecules attached to their surfaces. Some of these molecules are involved in producing the symptoms associated with allergies. Histamine is a chemical produced by some human cells. When histamine binds to molecules on the surface of cells that line the nose and throat, the cells will swell and leak fluid, causing the characteristic itching, sneezing, and congestion associated with allergies. A model of this mechanism is represented below.

Antihistamines are medications taken to block this reaction. Which of the antihistamine molecules represented below would be the most effective?

The structures most directly involved in the synthesis of cellular proteins are the:

nucleus and ribosomes

cell membrane and nucleus

chloroplasts and cell membrane

mitochondria and chloroplasts

The diagram below represents changes that take place within the human body.

The diagram represents:

cellular differentiation
