Term
| 1. What are the limitations to what the Scientific Method can answer? |
|
Definition
| Hypothesis must be testable and falsifiable. Can not prove or refute God or supernatural entity. Can not make value judgments like global warming is bad. |
|
|
Term
| 2. Why must an experiment be controlled? |
|
Definition
| Not exposed to the experimental variable, so there is a measurable difference between the control group and the experimental group. |
|
|
Term
| 3. Why can science not prove a universal statement? |
|
Definition
| Statements with words "all, always, no, or never" make the statement impossible to prove through experimentation. |
|
|
Term
| 4. Know the relationship between pure science and applied science. |
|
Definition
| Pure science is knowledge obtained through scientific activities. Applied science is using pure science to solve practical problems. |
|
|
Term
| 5. Why use a thin specimen with a light microscope? |
|
Definition
| You see the light that passes through the specimen, through the objective lens, through the body tube, and through the eyepiece lens. The objects you see are actually shadows. You want the light to pass through as little as possible. |
|
|
Term

|
|
Term
| 7. Be able to describe atomic theory. |
|
Definition

|
Term
| 9. Know the difference between an ionic and covalent bond. |
|
Definition
Ionic bond: A chemical bond between ions of opposite charge. Na+ Cl-
Covalent bond: A chemical bond formed between atoms as a result of sharing a pair of electrons. |
|
|
Term
| 10. Know the major functions of cellular organelles. |
|
Definition
chloroplast- photosynthesis
nucleolus -ribosome production
nucleus-DNA maintenance, RNA transcription
ribosome -translation of RNA into proteins
vesicle-material transport
rough endoplasmic reticulum-production of new proteins
Golgi apparatus-sorting and modification of proteins
cytoskeleton -gives shape to the cell
smooth endoplasmic reticulm-prodution of new lipids
mitochondria-energy production from oxidation of food and release of ATP
vacuole-storage, helps maintain homeostasis
lysosome-contains enzymes to help break down large molecules
centriole-anchor for cytoskeleton. Helps in cell division by forming spindle fibers |
|
|
Term
| 11. Understand the make up of the plasma membrane in a cell. |
|
Definition
| Selectively permeable to ions and organic molecules. Consists of the lipid bilayer with embedded proteins. |
|
|
Term
| 12. Understand the attributes of life. |
|
Definition
Derived from pre-existing life
Requires energy
Grows
movement,
Reproduction
Response
Faces death |

|
Term
| 13. Who was the father of Microscopy? |
|
Definition
|
|
Term
| 14. Know how a microscope magnifies an image. |
|
Definition
| You see the light that passes through the specimen, through the objective lens, through the body tube, and through the eyepiece lens. The objects you see are actually shadows. |
|
|
Term
| 15. Understand diffusion and osmosis and the difference between them. |
|
Definition
Diffusion-the random movement of atoms, ions, or molecules from an area of higher concentration to an area of lower concentration.
Osmosis-Diffusion of water molecules through a semipermeable membrane. |
|
|
Term
| 16. What makes something an organic compound? |
|
Definition
Naturally derived from living organisms.
Carbon |
|
|
Term
| 17. What is the relationship between amino acids and proteins? |
|
Definition
| Amino acid is the building block of a protein molecule. |
|
|
Term
| 18. Be able to describe an atom and an electron configuration. |
|
Definition
Atom: The smallest unit of an element that can exist alone or in combination.
C+4 |
|
|
Term
19. Know the differences between a chemical and physical change.
|
|
Definition
Chemical change: A change in which a substance loses its characteristics and changes into one or more new substances. iron into rust
Physical change: Altering a substance in its state of matter and appearance without changing it into a new substance. water into ice |
|
|
Term
| 20. Characteristics of enzymes. |
|
Definition
Proteins
Highly specific
Require energy to perform their functions
Release energy as they perform their functions.
Often require co-enzymes
Enzyme action is affected by heat, radiation, pH, chemicals
Enzymes most often work in series. |
