What are SI units for measuring length and volume?
metric system (centimeters, kilometers, etc.)
logistic growth curve
shows various growth phrases of a population, often ending in a steady state
expotential growth curve
depicts a sharp rise in population
abiotic and biotic factors
nonliving and living factors in an environment
autotroph and heterotroph
organisms that either make food or eat food
population and community
population= one speices in an area
community= many species in a given area
food chain and food web
food chain= one simple line of organisms
food web= many complicated, intercrossing lines of organisms
habitat and niche
habitat= where an organism lives
niche= habitat + job
water cycle
movement of water (the "source of life") through the biosphere
carbon cycle
movement of carbon between organisms and the air (atmosphere)
nitrogen cycle
movement of nitrogen through the biosphere between organisms and the atmosphere
phosphorus cycle
movement of phosphorus between soil, organisms, and air
environment with a characteristic climax community
climax community
relatively stable collection of plants and animals that results from ecological succession
limiting factor
a factor that prevents a species from reaching its full potential
primary succession
algae, moss, etc.
come after a natural/man-made disaster
secondary succession
climax community
pioneer species
first species to inhabit a place, usually after a natural disaster
density dependent factors and density independent factors
overcrowding, disease, etc.
natural disasters, storms, etc.
What are the main elements in living organisms?
carbon, hydrogen, oxygen, nitrogen
What are water's unique properties and how do they affect living organisms?
the molecule is slightly charged on each end, which leads to a very strong attraction and bond between various water molecules
What are the phases of water?
water, ice, gas, vapor
compounds and mixtures
chemically bonded
mixed together but not chemically
covalent and ionic bonds
share an electron between the atoms in the bond
give an electron to the other atom in the bond
elements and molecules
one type of atom
2+ atoms covalently bonded
mixtures and solutions
2 substances mixed together, not chemically
one substance chemically dissolved in another
solvents and solutes
a liquid that can dissolve a substance
substance that is dissolved
acids and bases
1-6.9 on pH scale
7.1-14 on pH scale
atomic number and atomic mass
number of protons in the nucleus
number of protons and neutrons in the nucleus
monomers and polymers
small compounds
larger compounds
single, double, many sugars
hydrolysis and condensation/ dehydration sysnthesis reactions
water splitting
remove water
organic and inorganic compounds
carbon/no carbon in the compounds
4 types of organic compounds found in living organisms
carbohydrates, lipids, proteins, nucleic acids
normally proteins, speed up reactions
components of a nucleotide
5-carbon sugar (deoxyribose), a phosphate group, a nitrogenous base
basic elements, subunits, function and examples for carbohydrates
carbon, two hydrogen for every one oxygen, monosaccharides, hold energy/sugar, glucose, fructose
basic elements and subunits for proteins
nitrogen, carbon, hydrogen, oxygen, amino group + carboxyl
basic elements, subunits, where found, function, and examples for fats/lipids
carbon, hydrogen, oxygen, glycerol + fatty acids, fatty acids, biological membranes, store energy, comprise biological membranes, cholesterol
basic elements, subunits, function and examples for nucleic acids
carbon, oxygen, hydrogen, nitrogen, phosphorus, nucleotides, hold genetic info, DNA, RNA
cell theory; contributors
The theory that all organisms are made of cells, and that all cells come from pre-existing cells. Cells are the structural and functional units of life.
Hooke, Schleiden, Brown, van Leeuwenhoek
3 major types of microscopes
light, scanning/transmission electron
differences between prokaryotes and eukaryotes
presence/absence of nuclei; presence/absence of organelles
3 basic parts of the cell
cell membrane, nucleus, cytoplasm
structures within the cell
2 types of endoplasmic reticulum
rough ER has ribosomes, smooth ER doesn't have ribosomes
how plant and animal cells different?
plants have a cell wall and a large vacuole
why is regulation of the movement of objects in and out of the cell important
so that only what is necessary is there
what is homeostasis?
process that keeps internal conditions constant
why do we say that plasma membranes are selectively permeable?
b/c only certain things can pass through
