Two factors within : Dependent and independent variable

Question 6

What is an independent variable?

Answer 6

It is varied / manipulated by the research

6. Growth
7. Responds to environment (stimuli)

Question 12

What is homeostasis?

Answer 12

When something maintains constant conditions

Question 13

Induction vs deduction : definitions

Answer 13

Induction : General to specific

Deduction : Specific to general

Question 14

What is an experiment?

Answer 14

A research study conducted to determine the effect that one variable has upon another variable by maximizing control over as many aspects of the environment.

Question 15

What is a immunological reaction?

Answer 15

Blood clumping that occurs when the receiver of a blood transfusion has antibodies against the donor blood cells

Question 16

Karl Landsteiner’s Significance

Answer 16

Made it possible to determine Blood Types and improve transfusion safety
Won the Nobel prize

Question 17

Red Blood Cells

Answer 17

Contains proteins (hemoglobin) that bind oxygen and transport it and remove carbon dioxide from tissues
Covered in proteins (antigens) that help signal when there is an invading organism in the blood stream and signal white blood cells to fight the invader

Question 18

White Blood Cells

Answer 18

Help to fight infections

Question 19

The platelets

Answer 19

Help the blood to clot (occurs when we get wound so we don’t bleed out)

Question 20

The Plasma

Answer 20

Contains salt and various kinds of protein

Question 21

What are the different blood types?

Answer 21

The difference in human blood types are due to the presence of a sense of certain antigens
The antigens are located on the surface of the red blood cells
Individuals have different combinations of these molecules
Blood group depends on what you have inherited from your parents

Chemical composition of blood

Question 28

What are antigens?

Answer 28

A toxin or foreign substance that induces an immune response in the body, especially the production of antibodies Located on the surface of RBC

Question 29

What are antibodies?

Answer 29

A blood protein produced in response to and counteracting a specific antigen Combine chemically with substances that the body doesn't recognize (invaders) Located in the Plasma

Question 30

What is agglutination?

Answer 30

Clumping of particles

Question 33

Type AB Blood

Answer 33

Both 'A' and 'B' antigens on the surface of your Red Blood Cells No antibodies

Question 34

Type O Blood

Answer 34

No antigens | 'A' and 'B' antibodies in your plasma
