What does evolutionary theory explain
Patterns of unity and diverseity in the living organisms
similar traits among organisms
and heritable changes
Hardy Weinberg equation
p^2+2pq+q^2=1 and p+q=1
What does Hardy Weinberg law state
That allele frequencies in a population will stay the same unless something causes them to change
What is something that “proves” thories
that we can predictt outcomes from then ex gravity on the moon or genetic diveristy
theme; evolution accounts for _______and _______ __ ___
unity , diverity of life
Theme; ____ requires energy ________ and __________
life, tranfer, transformation
Theme; organisms interact with ____ and ________ _________
other organisms, physical envirornment
Theme; _________ and ________ are correlated at _____________________
structure and function, all levels of biological organization
Theme; The Cell is an _______ ______ of structure and function
basic unit
Theme; the ________ of life is based on ________ _________ in the fform or ____
continuity , heritable informaton , DNA
Theme; _______ _________ regulate biological sys
feedback mechanisms
theme; ____ _________ emerge at ____ ______ in the biological hierarchy
new properties ,each level
What are emergent properties
Result from the arrangement interaction of parts within the system
aka new properties from getting more complex
What are isotopes
the same element with different number of neutrons
What determines the atomic #
of protons
____________ ____________ do not distinguish between isotopes
chemical processes
theory is
A well substantited explanation of some aspect of the natural world that can fax instances laws and testing hypotheses and other thories
What determines chemical properties in atoms
valence electrons
What is a compound
atoms joined by chemical bonds
What’s difference between single covalent bonds and double bonds
By the 1electrons/2 ele
Covalent bond
Shared valence electrons
Covalent bonds weak or strong
strong
What makes a covalent bonds polar
If one Adam is more electronegative than the other
What specifically water polar
the shape( two hydrogens on one side) Partial negative charge on the OXYGEN side Partial positive charge on the hydrogen site
What are ionic bonds
The form between a positively charged cation negatively charge anion
Ionic bonds strong or weak in or out of water
strong without water
weak in the water
think of salt
What are hydrogen bonds
between already bonded molecules
between other hydrogen molecules with weak bonds
Hydrogen bonds strong or weak
Weak
What is responsible for water being an good solevent
h-bonds
What is cohesion
What’s your sticking together because of (hydrogen bonds with one another)
What is adhesion
Water being attracted to other substances because of ionic or polar regions
Does the high specific heat of water help
1 help maintain constant internal temperature in organisms
2 stabilizes temperature of large bodies of water affects climate
What does Waters high heat vaporization mean
That hydrogen bonds must break and that’s the molecules carry heat causing evaporative cooling
What makes ice. less dence than liquid water
H-bonds
what does going from ice to gas in water mean for hydrogen bonds
moore bonds when solid few in gas
What is an acidic soluion
ph less than 7
more hydrogen ions
A basic PH
more than 7
more hydroxid ion
