molecules packed tight/ vibrate in place/ definite volume/ definite shape
Solid
causes evaporation and propels oceanic and atmospheric circulation.
sunlight
cannot be created nor destroyed
Matter
Inputs of photosynthesis
Carbon dioxide, water, and sunlight
when an organism is best suited to their environment, survives to reproduce and passes traits on to offspring
natural selection
What happens with kinetic energy as thermal energy increases?
increases
causes precipitation to fall from clouds and water to flow downward on the land.
gravity
List two indicators that a chemical reaction occurred.
Bubbles (gas formed)/ produces fire or light/ precipitate (solid formed)/ Temp change/Color change/Odor change/ rust (oxidation)
outputs of photosynthesis
oxygen and glucose
smallest unit of life
cells
As liquid increases in heat, what does it turn into?
Gas
What causes an increase in global warming?
Pollution
What happens to the total number of molecules AFTER a chemical reaction?
Stays the SAME
Where does the chemical reaction in animal cells occur?
mitochondria
2 letters that make up your code for a trait (Ex: BB/Bb/bb)
Genotype
energy transferred by direct contact is called?
Conduction
affected by sun, wind & density(salinity/ salt content)
ocean
What is a chemical reaction plants go through?
Photosynthesis
What is the main purpose of photosynthesis?
to make food for plants to survive
scientists inserts section of gene code into another species DNA// very precise
Genetic engineering
is a measurement used to determine how fast the particles are moving inside of a substance or how much energy the substance contains.
Temperature
most prevalent greenhouse gas =GLOBAL WARMING
Caused by burning fossil fuels (coal, gas, oil)/
Carbon dioxide
What kind of change does not form a new substance?
Physical change
what organelle do plants contain that animal cells do not have?
chloroplasts
