What is Geology?
Geology is the science which deals with the physical structure and substance of the earth, their history, and the processes which act on them.
Name the building blocks for all four major categories of organic molecules.
Carbohydrates
Proteins
Nucleic Acids
Lipids
Selection in which a mate is chosen based on certain trait or set of traits.
Sexual Selection
What is the difference between a covalent bond and an ionic bond?
Covalent = sharing of electrons between atoms
Ionic = one atom gives electron(s) to another atom
what are the three forms of life that first came?
prokaryotes, archae, and cyanobacteria
What is behavior?
An action or series of actions performed by an animal.
Name the six most common elements in organisms?
Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorous, Sulfur
Bonds that form between amino acids.
Peptide Bonds
What is the difference between an enzyme and a catalyst?
Both speed up reactions by lowering activation energy, but an enzyme is a biological (organic) catalyst.
what did cyanobacteria do to help the earth form?
released oxygen that formed the ozone layer
What is innate behavior?
Genetically programmed behavior.
Name the order of organs food passes through in the digestive system.
Mouth, Pharynx, Esophagus, Stomach, Small Intestine, Large Intestine
The area where a substrate interacts with an enzyme is called...
Active Site
What is the difference between genotype and phenotype?
Genotype - type of alleles an individual has (Bb); Phenotype - trait or characteristic that is actually exhibited (Black fur color)
what was the cambrian explosion?
an explosion of marine life
What is reasoning?
The ability to analyze a problem and think of a possible solution.
Name three differences between DNA and RNA
DNA: Double stranded, sugar is deoxyribose, nitrogenous bases include Thymine
RNA: Single stranded, sugar is ribose, nitrogen bases include Uracil instead of Thymine
Located on the female's chest or abdomen produce a nutrient-rich energy source called milk and give this class its name, Mammalia.
Mammary Glands
What is the difference between plant cell cytokinesis and animal cell cytokinesis?
Animal cells - formation of cleavage furrow; Plant cells - formation of cell plate (wall)
what was the KT event?
the theory that a huge meteor hit earth and killed the dinosaurs
What is imprinting?
Learning that can occur only during a specific period early in the life of an animal and cannot be changed once it occurs.
Name two organelles that are found in plant cells but not animal cells and give their function.
Cell wall - gives structure and support
Chloroplasts - responsible for making glucose through photosynthesis
Large Central Vacuole - storage of nutrients and wastes
The time when their mother stops nursing them.
Weaning
What is the difference between a saturated or unsaturated fatty acid?
A saturated fatty acid contains all single carbon-carbon bonds, thus it is "saturated" with hydrogen atoms. An unsaturated fatty acid contains at least one double carbon-carbon bond, and thus does not have as many hydrogen atoms.
what was the result of the Miller - Urey experiment?
simple organic molecules, amino acids, simple sugars, and adenine
