Scientific Method | Properties of Water | Macromolecules and Enzymes | Cell membrane and Homeostasis | Mitosis |
---|---|---|---|---|
What is the independent variable?
The variable that is manipulated by the scientist
|
What is cohesion
The property of water sticking to water
|
What are carbohydrates
These macromolecules function to provide us with short-term energy and are also called sugars
|
What is homeostasis
The tendency of our bodies and cells to remain within a certain range of conditions such as temperature and pH.
|
What is metaphase
The phase of mitosis in which chromosomes line up in the middle of the cell
|
What is the hypothesis
What you think is going to happen in your experiment
|
What are hydrogen bonds
The type of bonds water molecules make between each other
|
What are nucleotides
These building blocks of nucleic acids are made up of a sugar, a phosphate, and a base
|
What is hypertonic
A solution that has more solute than the solvent
|
What is anaphase
The phase of mitosis in which chromosomes are pulled apart by spindle fibers
|
What is the dependent variable
The variable that responds to the independent variable and is measured
|
What is solute
Water is called the universal solvent because it can dissolve almost any of these things
|
What are enzymes
This special type of protein catalyzes or speeds up reactions
|
What is
1. to protect the cell 2. to let things into and out of the cell 3. to maintain homeostasis
One function of the cell membrane
|
What is telophase
The phase of mitosis in which two nuclear membranes start to form
|
What is a theory
A well-tested hypothesis that is supported by many scientists
|
What is polarity
The property of water having positive and negatively charged ends
|
What are amino acids
The sequence of these determines the shape and function of a protein
|
What are proteins
These macromolecules transport large molecules through the phospholipid bilayer of the cell membrane
|
What is prophase
The phase of mitosis in which the nucleus disappears and chromatin condenses into chromosomes
|
What is the control
The variable that serves as a comparison of the natural conditions
|
What is capillary action
When water climbs up thin tubes due to cohesion and adhesion
|
What is the cell membrane
Phospholipids make up this organelle
|
What is osmosis
A type of passive transport in which water moves from an area of high concentration of solute to an area of low concentration of solute.
|
What is interphase
The phase of the cell cycle in which the cell spends most of its life, grows, copies its DNA and prepares for Mitosis
