evolution
What did Charles Darwin observe at the Galapagos islands?
tortoise shells were different, and the finches had all different shapes/sizes of beaks based on the island they were on.
what is a community?
multiple populations of DIFFERENT species
EX: herd of elephants and lions
what is the "hidden" allele called?
recessive
What are the reactants in photosynthesis?
sunlight, co2, water
What is the USEABLE for of energy in cellular respiration?
ATP
What does DNA evidence tell us about evolution?
more similarities in DNA = more closely related
why is an invasive species bad for an ecosystem? give an example of what it may do
- disrupts the food web
- stealing food from native species, eating native species or taking up space.
what does a Punnett square show?
the probability of inheritance in an offspring
what types of organisms go through photosynthesis?
Plants/autotrophs
what type of organisms go through cellular respiration?
ALL living organisms
what is natural selection?
organisms that are more adapted and suited for their environment are the ones who survive and reproduce
why is biodiversity important to an ecosystem?
- provides resources such as medicine, food, and supports food webs/ecosystem functionality
brown eyes= A
Blue eyes= a
what PHENOTYPE would an individual with "Aa" be?
brown eyes
what are the products of photosynthesis?
glucose and oxygen
What is the waste product (byproduct) of cellular respiration?
water
What are homologous structures and what do they tell us about evolution?
structures that have the same structure but different function
tell us that they have all evolved from a common ancestor
Why will there always be more prey than predators?
predators need to consume more energy to compensate for the 10% rule.
If you cross a Homozygous dominant individual with a homozygous recessive individual, what will the offsprings genotype be?
all heterozygous (Aa)
describe the importance of photosynthesis in the carbon cycle..
Plants help reduce/take out carbon from the atmosphere
give one benefit and one disadvantage to aerobic respiration
Benefit: provides some energy in time of a deficit
disadvantage: inefficient
Give an example and describe what behavioral isolation is...
when species selectively choose who to reproduce with based on a mate's behavior, mating dance/ritual.
-peacock spider dances for the attention of the female
describe or define all they types of symbiosis
Mutualism= ++
commensalism= +0
parasitism= +-
In incomplete dominance, describe what the phenotypes would be for a heterozygote..
a mix or blend of the other two phenotypes
AA=red
aa= white
Aa= pink
what is the equation for photosynthesis?
H2O+ CO2 + sunlight ---> O2 + Glucose
what's the equations for cellular respiration?
O2 + Glucose --> ATP + CO2 + H2O
