Overall Flashcards
Natural Selection
Process which traits that promote survivability are passed down to off-spring
Adaptation
Traits that enhance survival are passed to off-spring
Scientific name always include
Genus and species
Autotrophs
Product own food from inorganic substance (plants)(producer)
Heterotrophs
Obtain food by consuming plants or other animals
Primary consumers
herbivores(plant eater), or omnivores (meat and plant eater)
Secondary consumer
Carnivore (meat eater) or Omnivores that eat herbivores
tertiary consumers
carnivores that eat other carnivores or omnivores
symbiosis
separate species living together -include parasitism
parasitism
one species benefits and one is harmed- tapeworm
commensalism
One species benefits and one is not affected
mutualism
both species benefits from each other
Decomposer types
Bacteria and fungi
Decomposer function in ecosystem
consume nonliving organic material and release inorganic substance
Photosynthesis Reaction
CO2 + 6H2O - light–> C6h12O6 (glucose) + 6O2
Co-Dominance
Two dominate traits. Become mix
Isotope
same # of protons and neutrons
Ions
Charged atom, Lost electrons
Anion
negatively charged. Gained electrons
Horizontal rows of periodic table is
Period
Columns of the periodic table is
Group
non-polar bond
share pair of electrons equally
polar bone
shares pair of electrons unequally
Sublimation
Direct change from solid to gas
Test for starch
Lugol’s test (iodine) turns blue-black in starch
Test for monosaccharides
Benedict’s solution, when heated with simple sugar turns brick red.
Test for proteins
biuret solution
First law
_ objects in motion tend to stay in motion and that objects at rest tend to stay at rest
Second law
_ force applied on an object equals the mass of the object times its acceleration.
Third law
_ for every action there is am equal and opposite reaction
Kinetic theory of matter
_ atoms in matter are in constant state of motion
Boyles law
_ if volume of the gas decrease the pressure increases.
Charles’a law
_ define relationship between temperature and volume of gas.
Specific heat
_ the heat needed to raise substance of I gram by 1 degree
Latent heat
_ heat energy needed per unit mass to change the phase of a substance.
Doppler effect
_ ex pitch of the sound get higher as it approach but lower when it pass
Coulomb’s Law
; positive(protons) charge and negative(electrons) charge attract to unlike charge and repel same charge
fusion
_ light atoms combine to make single heavy nucleus with release of energy
Fission
_ heavy nucleus splits into two main pieces with the release of a huge amount of energy
