The Scientific Study of Life
All living organisms in an ecosystem.
What is a community?
Water's tendency to stick together.
What is cohesion?
The hydrocarbon functional groups.
What are alkanes, alkenes, alkynes, and aromatics?
Location of DNA in a prokaryotic cell.
What is the nucleoid region?
The general term for a prokaryotic cell with peptidoglycan in its cell walls.
What is bacteria?
These are the seven levels of taxonomy from broadest to most specific.
What is kingdom, phylum, class, order, family, genus, and species?
The ions formed when water is ionized.
What is hydronium (H3O+) and hydroxide (OH-)?
Compounds that have the same molecular formula but have different molecular structures.
What are isomers?
The organelle responsible for the synthesis and packaging of secretory proteins.
What is the rough endoplasmic reticulum?
An acellular entity that carries either DNA or RNA.
What is a virus?
The heritable trait that gives you the advantage due to natural selection.
What is an adaptation?
What the pH scale measures.
What is the concentration of H+ ions?
The simplest amino acid found found in animal proteins.
What is glycine?
Cellular compartments that store digestive enzymes.
What are lysosomes?
This organism was used in the first recorded successful vaccination.
What is Smallpox?
These are the seven steps of the scientific process.
What are observations, questions, hypotheses, predictions, tests, conclusions, and replication?
Avogadro's number.
What is 6.023 x 10^23?
These molecules have a sugar, nitrogenous base, and phosphate group.
What are nucleic acids?
These short hairs help paramecia move.
What are cilia?
This hypothesis stated that living organisms could arise from non-living matter.
What is spontaneous generation?
The difference between a dependent and an independent variable in a study.
The dependent variable is what is being measured, or the effect, and the independent variable is the constant, or the cause.
A factor that affects how well an enzyme works.
What is (any of the following) temperature, pH, substrate concentration, denatured enzyme?
The process by which monomers are linked together.
What is dehydration synthesis?
Both of these organelles contain their own DNA and can reproduce themselves.
What are mitochondria and chloroplasts?
The process of quickly heating then cooling a substance to kill organisms.
What is Pasteurization?
