Jim was told that he might need to go on medication if his blood pressure continues to be high. What causes blood pressure to increase?
More cholesterol/plaque in the blood

Removal of more oxygen from the blood
Cardiovascular disease runs in Jim’s mother‘s family. Jim is only 17 but knows that his mom and grandparents all have high blood pressure. Which of the following best describes the connection between cardiovascular disease and age?
As people age, their blood vessels become more elastic leading to less cardiovascular disease
As people age, the heart becomes more efficient with each pump, increase in cardiac output
As people age, low pressure decreasing to more cardiovascular disease
As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
The table below shows the average blood cholesterol levels in three patients along with the average range of cholesterol/plaque levels.
Using your knowledge of the cardiovascular system and the above data, which inference can most likely be made about the cardiovascular systems of Patient A and B?
Patient B’s blood is quickly circulating through the cardiovascular system, resulting in high blood pressure
Patient A’s blood is quickly circulating through the cardiovascular system, resulting in high blood pressure.
Patient B should increase salt intake to decrease blood volume to the average range
Patient A should hydrate with water to increase blood volume to the average range holiest
Which of the following events occurs during the first trimester?

Vas deferens
Seminiferous tubules
Scrotoum
epididymis
Although vaccines cannot be used to treat a person who is sick, they can help to prevent infections. Vaccinations tell the body to create "memory cells", which will function later to create antibodies against certain pathogens. When a person is vaccinated, what are they injected with?
antibodies to a disease bacterium
live, inactive viruses
weakened viruses or antigens from the virus
blood from a person who has had the disease
An activity that occurs in the human body is shown beside.
This activity helps to do which of the following?
provide protection against pathogens
produce antibiotics to control disease
eliminate harmful gene alterations
regulate production of ATP by the cell
Many species of bacteria have become resistant to antibiotics because antibiotics have been so widely used. Now, bacteria that used to be killed by antibiotics are more difficult to treat. What is the best way to proceed in dealing with this public health problem?
Antibiotics should no longer be used.
Antibiotics should be made available to anyone without a prescription.
Antibiotics should only be prescribed to people with bacterial infections.
Anti-viral medications should now be used instead of antibiotics.
Which of the following describes a way that a person's health can be affected by heredity?
A person with a family history of obesity is more likely to catch a common cold.
A person with a family history of high blood pressure is more likely to have heart disease.
A person with a family history of obesity is less likely to enroll in a weight loss plan.
A person with a family history of cancer is less likely to be screened for cancer.
The p53 gene codes for the p53 protein that locates DNA errors for cellular repair. The diagram below shows the relationship among possible environmental influences, the p53 gene, and cancer.
Which of the following statements best describes the relationships among possible environmental influences, the p53 gene, and cancer?
Environmental influences can lead to mutations in the p53 gene, which can cause certain cancers.
Increased levels of p53 protein, rather than environmental influences, can cause certain cancers.
Mutations in the p53 gene increase environmental influences that can cause certain cancers.
Genes such as p53 are less casual than environmental influences in stimulating certain cancers.
Which of the following factors would most directly affect blood flow through the circulatory system?
blood pressure
blood sugar
respiratory rate
outside temperature
What causes blood pressure?
cholesterol in the blood
stress that exercise puts on heart muscle
contraction of the ventricles in the heart
removal of oxygen from the blood
Which line in the graph beside best illustrates an effect of the carbon dioxide level in the blood on breathing rate before, during and after a period of exercise?
A
B
C
D
The rate at which blood flows through the human body changes in response to many factors. Which statement describes one of these factors and its effect on blood flow?
A high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
A low blood pH decreases the rate of diffusion through the blood vessels and leads to slow blood flow.
The changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.
The narrowing of blood vessels increases pressure and leads to a faster blood flow.

Many protists are single-celled organisms, as are bacteria. However, protists and bacteria are in different biological kingdoms. Which of the following comparisons of protists and bacteria is NOT true?
Both protists and bacteria can be motile
Both protists and bacteria are microorganisms

The Florida Panther was once considered to be a subspecies of cougars and given a special trinomial taxonomy of Puma concolor coryi. Current scientists however, have studied the Florida Panther and removed the subspieces classification to only Puma concolor. Which of the following would most likely explain why the classification of the Florida Panther changed.
New genetic evidence suggests a much closer relationship between the Florida Panther and other cougars.
Shared features between the Florida Panther and other cougars were also found in newly discovered organisms in the world.
Advanced technologies have shown a large difference in cell structure between the Florida Panther and other cougars.
Trinomial naming conventions are no longer used by longer used by scientists because only the genus and species are important in taxonomy.
Scientists have found evidence that about 2.4 million years ago a gene regulating jaw muscles mutated and may have led to the more graceful human jaw we see today. The diagram below shows the skulls of 3 hominid species.
Which statement below most closely explains the link between jaw size and hominid evolution?
The jaws of hominids evolved to be smaller and less protruding over time.
The jaws of hominids evolved to be larger and more protruding over time.
There appears to be no change in the jaws of hominids over time.
The jaws of hominids changed over time due to a change in brain size.
