Scientific Method Properties of Water Macromolecules and Enzymes Cell membrane and Homeostasis Mitosis
100
What is the independent variable?
The variable that is manipulated by the scientist
100
What is cohesion
The property of water sticking to water
100
What are carbohydrates
These macromolecules function to provide us with short-term energy and are also called sugars
100
What is homeostasis
The tendency of our bodies and cells to remain within a certain range of conditions such as temperature and pH.
100
What is metaphase
The phase of mitosis in which chromosomes line up in the middle of the cell
200
What is the hypothesis
What you think is going to happen in your experiment
200
What are hydrogen bonds
The type of bonds water molecules make between each other
200
What are nucleotides
These building blocks of nucleic acids are made up of a sugar, a phosphate, and a base
200
What is hypertonic
A solution that has more solute than the solvent
200
What is anaphase
The phase of mitosis in which chromosomes are pulled apart by spindle fibers
300
What is the dependent variable
The variable that responds to the independent variable and is measured
300
What is solute
Water is called the universal solvent because it can dissolve almost any of these things
300
What are enzymes
This special type of protein catalyzes or speeds up reactions
300
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
300
What is telophase
The phase of mitosis in which two nuclear membranes start to form
400
What is a theory
A well-tested hypothesis that is supported by many scientists
400
What is polarity
The property of water having positive and negatively charged ends
400
What are amino acids
The sequence of these determines the shape and function of a protein
400
What are proteins
These macromolecules transport large molecules through the phospholipid bilayer of the cell membrane
400
What is prophase
The phase of mitosis in which the nucleus disappears and chromatin condenses into chromosomes
500
What is the control
The variable that serves as a comparison of the natural conditions
500
What is capillary action
When water climbs up thin tubes due to cohesion and adhesion
500
What is the cell membrane
Phospholipids make up this organelle
500
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.
500
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
