Ecology
Organisms that make their own food using sunlight.
What are producers/autotrophs?
The organelle known as the "powerhouse of the cell."
What is the mitochondrion?
The macromolecule used primarily for long-term energy storage.
What are lipids?
The molecule that carries genetic information.
What is DNA?
The process by which plants use sunlight to make glucose.
What is photosynthesis?
The specific role an organism plays in its ecosystem.
What is a niche?
Cells that lack a nucleus.
What are prokaryotic cells?
The building blocks (monomers) of proteins.
What are amino acids?
The fusion of two gametes.
What is fertilization?
The scientific name for a graph that shows the relationship between two variables.
What is a scatterplot?
A network of interconnected food chains.
What is a food web?
The movement of water across a partially permeable membrane.
What is osmosis?
Biological catalysts that lower activation energy.
What are enzymes?
A type of cell division that produces genetically identical cells.
What is mitosis?
This term describes a variable that is kept the same throughout an investigation.
What is a controlled variable?
Because of these 3 things, only about 10% of energy is transferred from one trophic level to the next.
What is energy lost as heat, movement and waste?
The process that moves molecules against their concentration gradient using ATP.
What is active transport?
The process in which an enzyme loses its shape due to extreme heat or pH.
What is denaturation?
This hormone prepares and maintains the uterine lining after ovulation.
What is progesterone?
This measure of central tendency is calculated by adding all the values and dividing by the number of data points.
What is the mean?
Removing wolves from an ecosystem can lead to overgrazing by herbivores and changes throughout the food web.
What is a trophic cascade?
Plant cells become firm in a hypotonic solution because of this pressure against the cell wall.
What is turgor?
Breaking a polymer into monomers by adding water is called this reaction.
What is hydrolysis?
Crossing over and independent assortment during meiosis result in this.
What is genetic variation?
This statistical test is used to determine whether there is a significant difference between the means of three or more groups.
What is ANOVA?
