Module 1
The study of life
What is Biology?
The basic building block of matter
What is an atom?
The study of the interactions between living and nonliving things
What is ecology?
The basic unit of structure and function in living organisms
What is a cell?
The energy molecule of cells
What is ATP (adenosine triphosphate)?
Pasteur's experiment disproved this hypothesis that living things are formed from nonliving things
What is spontaneous generation?
Atoms are made up of these 3 subatomic particles
What are protons, neutrons, and electrons?
What is a food chain?
A cell with a membrane-bound nucleus and other distinct, membrane-bound organelles
What is a eukaryotic cell?
The process of making glucose from sunlight energy, water, and carbon dioxide
What is photosynthesis?
These are the 6 criteria for life
What are: Composed of cells, Grow and develop, Metabolism and energy, Homeostasis, Sense and respond to their environment, DNA and reproduction
A collection of atoms that all have the same number of protons
What is an element?
The 3 types of ecological pyramids ecologists use to depict either the amount of energy or mass in an ecosystem
What are energy pyramids, biomass pyramids, and pyramids of numbers?
The 2 basic ways that substances can enter or exit a cell
What are active and passive transport?
Process within all cells in which glucose (food) is broken down and energy (ATP) is is released
What is cellular respiration?
An organism that makes its own food
What is an autotroph?
A weak electrical attraction between a partially positive hydrogen atom and a partially negative atom of another molecule
What is a hydrogen bond?
These 5 cycles demonstrate how water, minerals, and other life-sustaining compounds are recycled
What are the water, oxygen, carbon, nitrogen, and phosphorous cycles?
The random motion of molecules from an area of high concentration to an area of low concentration until its concentration becomes equal throughout the area
What is diffusion?
This is the number of stages in cellular respiration
What is 4?
Process by which a single organism produces genetically identical offspring
What is asexual reproduction?
These 5 unique properties of water of water make it possible to support life processes
What are universal solvent, adhesion, cohesion, high heat capacity, and density?
These are the 3 major ways in which populations within a community interact
What are competition, predation, and symbiosis?
The diffusion of water through a semipermeable membrane from an area of high water concentration to low water concentration
What is osmosis?
What is the mitochondrion?
