Ch.1 Flashcards
Variable that changes
Independent variable
Conditions with a known outcome, the proof the independent variables is responsible
Control group
Part of the experiment kept the same
Constant
Simplest level of life
Cell
What surrounds a cell
Plasma Membrane
What levels can Multi cellular organisms be organized in?
Tissue, organs, systems
Producing offspring
Reproduction
Unique offspring
Sexual reproduction
Asexual Reproduction
Binary fusion(splitting)/budding, Genetic clones
Increase of material and larger structures and cells
Growth
Structural formation/changes
Development
Do unicellular organisms developed?
Yes, by making new structures
Do multi cellular organisms develop?
Yes, cell structures, and new arrangements in tissue and organ
Non living things don’t grow by
Internally producing cells
Power to make things change;
Energy
Using energy, simple combine into complex molecules
Anabolic reaction
Producing energy, by breaking down complex into simple molecules
Catabolic reaction
Catabolic+Anabolic reactions
Metabolism (chemical reaction, food to energy)
Make food from (non living substance), usually the sun
Autotrophs
Get energy from organizing they consume
Heterotroph
Organisms regulation to the environments changes
Homeostasis
Use senses to gather info
Observation
Interpretation based on prior knowledge/experience
Inference
Testable explanation for an observation
Hypothesis
Amount of Protons
Atomic #
Protons and Neutrons
Atomic mass
Different Neutrons amount
Isotope
Bond between Non metals, sharing electrons
Covalent Bonds
Bond between a metal and nonmetal, ion steals and electron creating a positive an negative charge
Ionic bonds
Positively or negatively charged atom
Ion
Matters basic unit and an element structure
Atom
Same Adam, either alone or bonded
Pure element
2+ atoms ( same or different ) covalently bonding
Molecule
Different atoms bonded (covalent or ionic )
Compound
Different atoms bonded (covalent or ionic )
Compound
Triple covalent bond
Sharing of six electrons
Six atoms lifting things are made of:
Oxygen, hydrogen, carbon, nitrogen, sulfur, phosphorus
