Intro to Bio
A constant is
What is kept the same, except for one variable
Parts and charges of an atom
Neutron --> No Charge
Protons --> Positive
Electrons --> Negative
Four major types of macromolecules
What are carbohydrates, fats, proteins, and nucleic acids
Cells that hold no nucleus.
What are prokaryotic cells?
Alleles which are the same
What is Homozygous?
The five steps of the Scientific Method.
What is Observation, hypothesis, experiment, record data, and draw conclusion.
The number of protons and electrons
What is the atomic number
What are Saturated fats.
This part of the cell is responsible for cholestrol and lipid synthesis.
What is the Smooth ER?
A portion of DNA with a code for protein to regluate its expression
What is a gene
A hypothesis must be
What is testable, logical, and make the least amount of assumptions.
Number of protons and nuetrons
What is Mass number.
macromolecule made of amino acid
What are proteins
Transport that requires protein to help with transportation.
What is Facilitated Transport?
Occurence of Alleles separating into gametes during meiosis
What is the Law of Segregation?
The difference between manipulated and dependent variables.
Independent is what YOU change in an experiment while dependent is the result of the change.
Atoms of the same element that have different amounts of neutrons
What are Isotopes.
Plants store this as starch and animals store as glycogen
What are Carbohydrates?
The part of the cell that acts as security and decides what can leave and enter
What is the Plasma Membrane?
The masking of other alleles
The Law of Dominance
Six characteristics of Life
What are Levels of Organization, Acquire Materials and Energy, Homeostasis, Respond to stimuli, Reproduce and develop, and Adapts to changes.
The arrangement of electrons in an atom
What is 2 in the innermost shell and 8 in the other shell
(If nitrogen 2 in first, 5 in outer)
A benefit of nucleic acid; nade of nucleotides, adenine pairs with Thymine, Cystone pairs with Guanine, and double stranded.
What is DNA?
The movement of molecules from a high concentration to an area of low concentration
What is Diffusion?
Alleles segregate independently with other pairs. Resulting in all combination of factors as a possibility.
What is the Law of Independent Assortment?
