Week 1
Define Biotic
A living thing
Define Biosphere
all living things and once living things
Define Homeostasis
Internal balance, equilibrium
Define Mutation
Random changes in the DNA code.
Define Photosynthesis
process of converting light energy into stored chemical energy (glucose) equation!!
A diagram that shows a singular pathway of energy flow
Define Hydrosphere
all water on our Earth (oceans, rivers, ground water etc)
Define Interact
To work together
Define Survival
The ability of an organism to stay alive within the conditions of their environment.
Define Protein
Macromolecules that are made of amino acid chains that need specific shapes to do their function (like a key).
Define Consumer
An organism that must consume another organism for food
Define Carbon Cycle
the movement of carbon through the 4 spheres of earth through molecular recycling processes
Define Amino Acid
The subunits, or building blocks, or proteins.
Define Advantage
When your traits help you better survive and reproduce within your environment.
Define Natural Selection
The process by which nature selects which variation within a species has an advantage that helps them better survive and reproduce.
Define Limiting Factor
a factor that determines the carrying capacity; can control the size of a population
Define Store Chemical Energy
glucose, holds carbon
Define Urinary System
The group of organs that interact to filter your blood to remove waste from your body.
Define Transcription
Process that occurs within the nucleus to make mRNA using DNA.
Define Evolution
A change in species over many generations.
Define Carrying Capacity
The maximum population of a species that an environment can support
Define Molecular Recycle
Process that uses enzymes to break down molecules into smaller pieces, so that they can be recycled (transformed) into something else.
Define Respiratory
The group of organs that interact to take oxygen into your body and remove CO2 from your body.
Process that occurs within the ribosome to make protein using mRNA.
Equations for Photosynthesis and CR
Photosynthesis: CO2 + H20 + Sunlight --> Glucose + O2
Cellular Respiration: O2 + Glucose --> CO2 + H2O + ATP
