When a human system fails to function properly, the most likely result is this.
What is a disturbance in homeostasis.
100
True or False. Cells in the nervous system are different in structure from cells in the circulatory system, and they carry out different specialized functions.
What is true.
100
These structures work together in order for nutrients to get to all the cells of the body.
What is the villi of the small intestine and capillaries.
100
The hormone produced in structure A most directly brings about change in this.
What is physical characteristics.
100
Allergic reactions are most closely associated with this.
What is an immune responses to usually harmless substances.
200
When a person does strenuous exercise, small blood vessels (capillaries) near the surface of the skin increase in diameter. This change allows the body to be cooled These statements best illustrate.?
What is homeostasis.
200
These are characteristics of asthma.
What is build up of thick mucous in the alveoli and damage from lung infections.
200
These two organs secrete enzymes into the digestive system to help breakdown food. Does food pass through these organs?
What is the pancreas and liver. No food does not pass through these organs.
200
This pair of letters indicate the structure that produces gametes and the structure that makes the delivery of gametes for internal fertilization possible.
What is A and D.
200
Neurotransmitters, or secretions of the nervous system are chemical messengers that? do this.
What is coordinates systems interactions.
300
This process is an example of what?
What is a feedback mechanism maintaining homeostasis.
300
This is caused by a loss in elasticity of blood vessels due to cholesterol deposits.
What is high blood pressure.
300
The most immediate response to a high level of blood sugar in a human is an increase in this.
What is the release of insulin.
300
The process represented in the diagram is this.
What is a zygote dividing by mitosis.
300
White blood cells help maintain homeostasis in these three ways.
What is 1) destroy foreign antigens 2) produce antibodies 3) engulf bacteria
400
Homeostasis is maintained during strenuous exercise in these ways.
What is increased breathing and increased blood flow to muscle cells.
400
The structures that are interacting in this diagram are what. Why is this interaction necessary for life?
What is the alveoli of the respiratory system and the capillaries of the circulatory system. Oxygen enters the blood during this interaction which is delivered to all cells of the body in order for cells to carry out cellular respiration.
400
Hormones are chemical messengers that do this.
What is carry out circulation of materials.
400
A heavy dose of radiation would have the greatest impact on genetic information in future offspring if it reached which of these structures.
What is A. the ovary.
400
This is a cause for failure of a muscle cell to respond to a stimulus.
What is a neuron fails to release neurotransmitters (or damage to the neuron).
500
This graph represents blood sugar level over a 12 hour period in dynamic equilibrium.
What is graph C.
500
In an investigation to determine the change in heart rate with increased activity, a biology teacher asked students to take their pulses immediately before and immediately after exercising for 2 minutes. The data showed an average heart rate of 72 beats per minute before exercising and 90 beats per minute after exercising. This is a valid conclusion that can be made from the results of this investigation.
What is the heart rate of each student goes up 18 beats after jogging for 2 minutes.
500
A hormone may attach to one cell but not another. Why might this be?
What is hormones are specific.
500
New inherited characteristics may appear in offspring as a result of new combinations of existing genes or may result from mutations in genes contained in cells produced by this structure.
What is B. the ovary.
500
What is occurring in this diagram?
What is the marking of a microbe by a specialized cell and the engulfment of the microbe by another cell during an immune reaction.
