CH.1: Study of Life
What is the difference between law and theory?
law= describes a pattern in nature
theory= explanation of why a pattern exists
Define differences between protons, neutrons, and electrons.
protons: positive charge, in nucleus
neutrons: no charge, in nucleus
electrons: negative charge, no mass, in valence shells
Define between nature vs. nurture
nature: biological influences
nurture: environmental influences
what is population?
abiotic: nonliving, sunlight, soil, etc
biotic: living, autotrophs, producers, etc.
Difference between inductive reasoning and deductive reasoning?
inductive= makes generalizations based on large observations
deductive= general premises -> prediction -> scientific results
Define an isotope and what rule it follows regarding stability.
isotope are atoms of the same element that have a different number of neutrons, octet rule
define alturism
the ability to be completely selfless for the benefit of others
what is doubling time?
define autotrophs
producers
What is the difference between experimental variables and response variables?
response= dependent, result or change that occurs due to experimental variable
describe the function of ATP in cells.
provides energy
Describe the advantages and disadvantages of chemical, auditory, visual, and tactile communication.
chemical- dis: you have to find and smell out a specific spell// ad: know it is your own species
auditory: dis: have to understand the langauge // ad: more specific points
visual: dis: what if you cant see, has to be at night // ad: fastest form of communication
tactile: dis: you have to be able to feel // ad:
what is density independent factors and give an example?
abiotic factors such as weather and natural disasters
what is the water cycle?
evaporation -> condensation -> precipitation
What are the characteristics of life?
-organized
-aquire materials and energy
-reproduce
-respond to stimuli
-maintain homeostasis
-grow and develop
-can adapt evolutionarily
What are the different kinds of bonds?
ionic bond, covalent bond, nonpolar covalent bond, polar covalent bond, hydrogen bond
Examples of imprinting, classical conditioning, and operant conditioning
make up your own!
biotic factors such as competetion, predation, and parasitism
what are aquifers
rock layers that contain water and release it in appreciable quantities to wells or springs
What are the levels of biological organization?
atom -> molecule -> cell -> tissue -> organ -> organ system -> organisms -> species -> population -> community -> ecosystem -> biosphere
compare and contrast DNA and RNA
DNA vs RNA
Sugar// deoxyribose ribose
Base// adenine, guanine, uracil
thymine, cytosine
Strands// double-stranded single
Helix// yes no
What is alturism and why might it evolve?
alturism is the selfless behavior to benefit others over yourself
list the types of symbiosis and who it benefits
parasitism: one benefited and one harmed
commensalism: one benefited the other has no effect
mutualism: both benefited
what are the three factors chemical cycling may involve?
1. reservoir- a source normally unavailable to producers
2. exchange pool- a source from which organisms generally take chemicals (atmosphere, soil)
3. biotic community- through which chemicals move along food chains
