A Crime Scene Investigator (CSI) is called to the scene of a mysterious death. Which of the following is NOT one of the initial steps used to process a crime scene?
Interview witnesses to establish a theory of the case.
Examine the crime scene and mark any evidence.
Perform DNA analysis on all biological samples.
Sketch a diagram of the crime scene.
Investigators collected the following evidence from a crime scene: Type A blood, Dyed brown hair, Whorl pattern fingerprint, and a Shoe print. Suspect #1 was found to have type A blood, dyed brown hair, low similarities in fingerprint match and hiking shoes. Which of the following could be used to potentially eliminate suspect #1 as a suspect?
Blood type A
Dyed brown hair
The fingerprint
The graph represents the diameter of the bloodstain (cm) versus the height from which it was dropped (cm). Using the graph, from what height was the blood most likely dropped that would result in a blood stain pattern with a diameter of 1.9 cm?
80cm
120cm
150cm
200cm
A student tested four unknown food samples for their nutritional content. The student's results are recorded in the table below. According to the table, which unknown sample would be the least healthiest choice?
Unknown sample 1
Unknown sample 2
Unknown sample 3
Unknown sample 4
On a cold day, a person's body temperature begins to drop. The cold stimulates this person's brain cells. The brain cells send a signal to other cells that release a hormone that starts a biochemical pathway. This increases the metabolic activity of the cells of the person's body. The increased cellular activity produces heat. This heat helps restore this person's normal body temperature. When the body temperature is normal, the brain cells stop sending a signal. Which type of process does this example describe?
A positive feedback loop
A cause-effect feedback loop
A negative feedback loop
A neutral feedback loop
The diagram represents the molecular structure of an organic compound. Which class of macromolecules uses this structure as a building block?
Fats
Carbohydrates
Nucleic Acids
Proteins
Which statement best describes how complex molecules in food are broken down into simpler molecules?
Sugars break down into starch
Monosaccharides break down into polysaccharides
Triglycerides break down into lipids
Proteins break down into amino acids
What does an elevated white blood cell count typically indicate?
A defect in the liver
Anemia
A rise in oxygen concentration
An infection
Which of the following describes how the protein hemoglobin helps red blood cells?
It carries oxygen to the tissues of the body
It monitors glucose levels in the body
It protects the body from viruses and bacteria
It carries oxygen to the tissues of the body
What is the primary factor that determines the three-dimensional shape of a protein?
The structure of the peptide bonds
The sequence of amino acids
The sequence of peptide bonds
The structure of amino acids
What is the term for distinct segments of DNA that differ from person to person?
Chromosomes
Traits
Nucleotides
Genes
How are sickled red blood cells different from normal red blood cells?
Sickled red blood cells have an increased ability to fight infections
Sickled red blood cells have an increased ability to carry wastes
Sickled red blood cells have a decreased ability to carry oxygen
Sickled red blood cells have a decreased ability to carry nutrients
Which statement about blood pressure is true?
The top number of blood pressure reading represents the pressure exerted on the vessels when the heart is relaxing
Factors that can increase blood pressure include stress, a high salt diet, and cholesterol buildup in the blood vessels
Blood pressure can be measured directly with an EKG
A blood pressure reading of 160/100 is considered a healthy blood pressure
Both the respiratory system and circulatory system are necessary for the delivery of oxygen to body tissues. Which statement correctly explains how these two systems work together?
The lungs supply the oxygen and the veins deliver the oxygen to the body
Capillaries surround the alveoli and allow oxygen to diffuse into the blood stream to be transported to body tissues
White blood cells bind to oxygen from the lungs and carry the oxygen to the body tissues
Oxygenated blood moves from the bronchial tubes to the aorta and then is transported to the body tissues
Which condition would be a consequence of a malfunction in the large intestine?
Acid reflux
Salivation
Diarrhea
Ulcers
How does the urinary system maintain cellular homeostasis?
Delivers oxygen to cells
Regulates water balance
Separates damaged cells
Regulates blood sugar
What was the control?
I. Weight gain
II. Decreased urination
III. Feeling hungry
IV. Feeling thirsty
V. Weight loss
VI. Hyperactivity
I. A diet low in carbs
II. Exercise
III. Insulin
IV. Anti-viral drugs
V. Warmer climates
Which lipoprotein takes up more room?
LDL
HDL
Can someone be a carrier of the FH gene? Why or why not?
Yes, because it is recessive
Yes, because it is dominant
No, because it is recessive
No, because it is dominant
What shape are these bacterium?

bacillus
spirilla
none of these
What shape are these bacterium?
coccus
bacillus
spirilla
none of these
Which of the following is not true about Sickle Cell Anemia?
It is most common among those of African descent.
It is caused by the genetic mutation that replaces GLU with VAL in the hemoglobin protein
It is caused by a frame shift mutation
It has a protective factor for malaria
The reason someone dies is called the:
type of death
manner of death
cause of death
mechanism of death
A method for the differential staining of bacteria that involves fixing the bacterial cells to a slide and staining with crystal violet and iodine, then washing with alcohol, and counterstaining with safranin. Results in gram-positive bacteria retaining the purple dye and gram-negative organisms having it decolorized so that the red counterstain shows up.
Gram Stain
Aseptic Technique
Microbiology
Transmission
A spherical bacterium.
Coccus
Bacillus
Spirillum
Prion
