Everything You Need To Know For Your First Semester Biology Final
Transcript of Everything You Need To Know For Your First Semester Biology Final
properties of the molecules they compose Monomer/Polymer/Macromolecule: Different sizes of organic compound molecules Organic compounds: Compounds that contain carbon atoms covalently bonded to other elements Amino acids/Dipeptide/Polypeptide: Different protein molecules Monosaccharide/Disaccharide/Polysaccharide: Different Carbohydrate molecules Fatty acid/Wax/Triglyceride/Phospholipid/Steroid: Type of lipids Large, non-polar molecules that
DO NOT dissolve in water Hydrophobic/Hydrophilic: water-fearing/loving Isomer: Different forms of the same compound that share the same chemical formula Nucleic Acid: Large, complex organic molecules
that store genetic information Nucleotide: Repeating monomers in DNA and RNA; contains phosphate group, 5-carbon sugar, and a nitrogen base :Peptide Bond covalent bond that holds 2 amino acids together RNA: Molecule that stores and transfers information for the manufacturing of proteins Substrate: substance being catalyzed by and enzyme Essential Learning 2: Scientific Method Reproduction: Organisms transmit genetic
information to their offspring Asexual: Hereditary information from
one cell gives rise to another :Sexual Combination of egg and sperm
from parents to form offspring Autotrophs/Heterotrophs Organisms that eat/produce Differentation: process through which cells
specialize during development DNA: deoxyribonucleic acid Ecosystem/Ecology: environmental communities and the study of ecosystems :Evolution/Evolve change over time Gene: short segment of DNA that controls a single trait Homeostasis: maintaining a stable
internal environment Multicellular/Unicellular Organisms: Organisms with many/one cell/s Any living thing :Natural Selection Driving force behind evolution Photosynthesis: process through which sunlight and water are combined to make sugars and carbon dioxide. Cell Division: Formation of 2 cells from an existing cell :Development Process by which an adult organism arises Metabolism: Sum of all chemical processes
that occur in an organism Experimental Group/Control Group: Groups in an experiment, where the only difference is whether it has the independent variable Scientific Method: Hypothesis Experiment Observation Prediction Data experiment based
on the comparison
of an experimental
and a control group controlled
experiment Dependent variable: Effect that occurs due to
the independent variable Independent variable: variable that is tested in
a controlled experiment Inference: conclusion made on
the basis of facts,
rather than direct
observations -perceive -see ahead -guess Test- -Organize your findings model: shows relationships,
supported by data Sampling: using a small part of a population
to represent the entire population Theory: Broad, comprehensive statement
of what is thought to be true SI/base units/
derived units: system of units of measurement Compound Light Microscope: microscope that uses light passing
through an eyepiece and an objective
lens to magnify objects Electron Microscope: uses a beam of electrons
to magnify images scanning electron microscope-scans transmits-transmission electron microscope Parts: microscope-tool used to magnify objects nosepiece-structure used to support the objective lens in a compound light microscope objective lens-lens of various magnifications used to enlarge images ocular lens-lens found in the eyepiece of a compound light microscope stage-holds the slide on a compound electron microscope
