The Study of Life
This variable is the one often changed by the scientists
Independent variable
A relatively weak bond between atoms of different charges
ionic
These organelles contain enzymes that help clean up the cell
lysosomes
This part of mitosis is when the sister chromatids separate
Anaphase
Term for something that may cause cancer
Carcinogen
These are conditions that don't change in the experiment
Constants
Type of bond found that holds water molecules together
Hydrogen bond
This is when Transport proteins in a cell membrane help materials pass through with the concentration gradient
facilitated diffusion
This is why cellsundergo mitosis
1) To grow
2) To replace dead, dying, injured cells
Four carbon based molecules important to life.
Proteins
Carbohydrate
Lipds
Nucleic Acids
This is the group that does not get the intervention in an experiment. They sometimes get a placebo.
Control Group
This measure how much energy it take to change a substances temperature
Specific Heat
These two organelles for the cytoskeleton
microtubules
microfilaments
This is what limits the size of cells
Surface Area to Volume Ratio
Mitochondria makes this molecule
ATP
This changes the amount of light going into the microscope
Diaphagm
This property of Water descibes how it sticks to other things like the siide of a mug
adhesion
If a cell membrane is permeable to water and the cell is placed in a ___________ solution, water will leave the cell
hypertonic solution
When a cells chromosomes are duplicated
S Stage
Molecule that chromosome wrap around
Histones
These hold the slide in place on a microscope
stage clips
A solution with a high H+ in concentration
Acid
when the two solutions have the same concentration
isotonic
Programmed cell death
Apoptosis
Amount of enery necessary to break a bond
Bond Energy
