As the temperature of air cools down, the air __________ (in other words, it becomes _______ dense)
As Air Density Increases, Air pressure also _________________
As Air pressure Decreases, air density also _________________
The most common gas in the atmosphere (76%) is ___________________
The second most common gas (22%) in the atmosphere is ________________.

5. Key Atmosphere Concepts that you MUST know!
Fluids (such as air) move from areas of ________ pressure to areas of ________ pressure
Air pressure is different in different places on Earth because…
Air moving from areas of high pressure to areas of low pressure parallel to Earth’s surface is called _____.
The measurement of how much water vapor is in the air is called ________________.
The warmer air is, the ______________ humidity it can hold.
When water vapor condenses on dust particles in the atmosphere, ___________ are formed

6. Key Atmosphere Concepts that you MUST know!
A drop in air pressure in an area indicates a _____________ front.

7. Characteristics of Living Things: Vocabulary
A living thing-- this is an individual example of a specific species of living thing. ORGANISM

8. Comparing Similarities Between Living Things

9. Characteristics of Living Things: Vocabulary
There are seven characteristics that all living things share with one another:
All living things RESPIRATE
All living things EXCRETE waste
All living things require NUTRIENTS
All living things GROW
All living things REPRODUCE
All living things are SENSITIVE to their environment
All living things MOVE
***Of course within any species, there are injuries or problems with the body that can cause one of these features to not work properly– this does not mean that the organism isn’t “alive”. For instance, a dog who has had its reproductive organs removed (spayed or neutered) is not suddenly a “non- living thing”

10. Introduction to Cells: Vocabulary
This is the smallest individual part of an organism that can still be considered "alive". It is capable of carrying out all life functions that living things do (such as respirate, excrete, reproduce, etc.) CELL

11. Introduction to Cells: Vocabulary
This is a type of organism made of many cells working together. An example would be a human being
MULTICELLULAR ORGANISM

12. Introduction to Cells: Vocabulary
This is a type of organism that is made of only a single cell. An example of this would be bacteria. UNICELLULAR ORGANISM

13. Introduction to Cells: Vocabulary
These are microscopic, single-celled organisms that live everywhere. Some types of these cause food to spoil; other types of these can make you become sick.
BACTERIA

14. Today’s Topic:
What is the difference between a eukaryotic cell and a prokaryotic cell?

15. Eukaryotic Cells vs. Prokaryotic Cells: Vocabulary
These are a type of cell that does not contain a nucleus; instead, all genetic material (DNA) is found floating freely in the cytoplasm
PROKARYOTIC CELLS

16. Eukaryotic Cells vs. Prokaryotic Cells: Vocabulary
These are a type of a cell in which the cell's genetic material (DNA) is found inside a nucleus
EUKARYOTIC CELLS

17. Prokaryotic Cell: Eukaryotic Cell
How are prokaryotic and eukaryotic cells different?
Eukaryotic cells have distinct and separate parts, called ORGANELLES, that carry out life processes. Prokaryotic cells do not have separate and distinct organelles.
Eukaryotic cells have DNA in their nucleus; Prokaryotic cells have DNA that freely floats in the cytoplasm
DEOXYRIBONUCLEIC ACID (DNA)-- This substance includes all of the genetic information for how a living thing is put together.

18. Prokaryotic Cell: Eukaryotic Cell
Most unicellular organisms are PROKARYOTIC
Most multicellular organisms are EUKARYOTIC

19. The Organelles of a Cell: Vocabulary
This is the gelatin-like liquid that makes up the majority of the cell. CYTOPLASM This is the outer layer of a cell that separates and protects the cell from the environment around it. CELL MEMBRANE This is the organelle in a eukaryotic cell which in which you would find the genetic material (DNA) for the cell. NUCLEUS
