Replication
Transcription
Translation
Protein synthesis
Organism whose DNA is surrounded by a nucleus.
Prokaryote

Why is the mitochondria called the powerhouse of the cell?
because it releases energy from food in cellular respiration
because it creates food in photosynthesis
because it stores food for future metabolism
because it makes proteins
The graph shows the number of mitochondria in breast muscles of different birds. Which statement best explains these data?
The number of mitochondria in chickens would be higher if they could fly.
The chicken breast muscle requires the greatest amount of energy per cell.
The energy requirement of pigeon breast muscle is low.
Duck breast muscle require the least amount of energy.

Passive Transport
Osmosis
Simple Diffusion
Active Transport

Control Group
Experimental Group
Natural Group
Dependent Group
A good scientific experiment should
make observations at regular intervals
use metric measurements
have a control group
Do all of these
Which of these should you NOT do with a microscope?
Start in low power (4x), focus, and work your way up.
When you are in high power (40x) use the coarse adjustment knob to focus.
When you are done, return the microscope to the lowest objective lens.
If you get lost, return to low power and start over.
