Topics covered on Exam:
Levels of Organization (Cell, Tissue, Organ, Organ System, Organism)
Characteristics of Living Things
- Composed of cell(s)
- Reproduce
o What are the different types of reproduction? Give me an example of an
organism that reproduces each way.
- Contains genetic material
- Grows
- Metabolism (Obtain nutrients, digestion, cellular respiration, excretion)
- Maintains homeostasis
- Responds to Stimuli
- Evolves
*You should be able to describe/define each of these characteristics.
Identify major function of the Organ (Body) Systems:
- Muscular
- Skeletal
- Circulatory
- Respiratory
- Nervous
- Digestion
- Excretory
- Endocrine
- Reproductive
* Can you describe a place in the body where DIFFUSION takes place? What substances
diffuse there? Hint: Respiratory, Circulatory or Digestive Systems
* You will NOT be tested on organs and their functions.
Compare how life processes are carried out in Unicellular and Multicelluar Organisms
- Unicellular – Organelles
- Multicellular – Organ Systems
* You should know specific examples of differences.
Negative Feedback Mechanism
- Body Temperature
- Blood Sugar Level (Insulin)
o How do cell receptors play a role in this example? Why does insulin only bind
to insulin cell receptors?
- Guard Cells (Plants)
*You should be able to describe (in detail) at least one of the feedback mechanism.
Dynamic Equilibrium
- What happens if an organism cannot maintain homeostasis through dynamic
equilibrium?
Pathogens (Virus, Bacteria, Fungi, Parasite, Protozoan)
- You should know the general characteristic of each of these microbes. You will NOT
be tested on specific examples.
- You should know how to treat each disease.
- What is a vaccine? What does it do?
- Are viruses living? Why is this question a debate? How do viruses reproduce?
Causes of diseases (Briefly describe theses causes of disease. Could you explain an example of
each?)
- Pathogens (see above)
- Genetic Disorders
- Exposure to Toxins
- Poor Nutrition
- Organ Malfunction
- High Risk Activities
- Can you describe an example of a disease/problem that could cause a specific organ
system to malfunction? What would that disease/problem cause to happen? What
would be the effect?
Immune Response
- Describe the steps of an immune response.
- Macrophages, Helper T-Cells, Killer T-Cells, B-Cells and Plasma Cells are all TYPES of
White Blood Cells! Each of them have a specific job in the immune response. What
is the job of each of these cells?
- Antibodies are proteins and have a SPECIFIC shape! Antibodies are NOT a type of
White Blood Cell.
- What is an allergy?
HIV
-
What type of pathogen is HIV?
What is AIDS?
What organ system does HIV attack?
What are two ways that HIV attacks/weakens this organ system?
How can you prevent/control the spread of this disease?
