Unit 1: Intro to Bio
A proposed scientific explanation for a set of observations.
What is a hypothesis?
This represents the number of protons in an atom.
What is atomic number?
This is the amount of energy that passes from one trophic level to the next.
What is 10%?
These organisms reproduce rapidly in new environments, posing a threat to native species.
What is an invasive species?
This type of cell lacks a nucleus and membrane-bound organelles.
What is prokaryotic?
What is qualitative data?
This type of bond forms between two water molecules.
What is hydrogen bond?
This process removes carbon from the atmosphere.
What is photosynthesis?
This type of gas destroys the ozone layer.
What is CFCs?
This organelle makes proteins.
What is ribosomes?
Maintaining a stable internal environment.
What is homeostasis?
What is a nucleotide?
This level of organization includes all the populations living together.
What is a community?
This occurs when concentrations of harmful substances increase in organisms at higher trophic levels.
What is biological magnification?
This prevents plant cells from bursting when placed in a hypotonic solution.
What is the cell wall?
An experiment in which only one variable is changed.
What is a controlled experiment?
This is what happens to an enzyme when the temperature exceeds its optimum.
What is denature?
This is the maximum number of organisms that an environment can support.
What is carrying capacity?
This refers to the long-term warming of the planet resulting from increased greenhouse gas emissions.
This type of cell transport requires the help of a protein to move molecules from an area of high concentration to an area of low concentration.
What is facilitated diffusion?
A variable that is purposely changed by the scientist.
What is an independent variable?
This is where the substrate binds to an enzyme.
What is active site?
This type of symbiosis involves one species benefiting, while the other remains unaffected.
What is commensalism?
This is caused by carbon dioxide dissolving in the ocean, leading to the destruction of shells and coral.
What is ocean acidification?
In this type of solution, the solute moves into the cell, and water moves out.
What is hypertonic?
