you spend lots of time and money developing a new weight-loss drug. before you can sell your drug (and make $ from it), you need to provide evidence that your drug actually does help people lose weight. you create the following experimental design to test your drug:
you find 100 volunteers and put them into the following two groups:
group 1: 50 people who will take the new drug for 6 months
group 2: 50 people who will take a sugar pill daily for 6 months
you decide to have all individuals in the study show up to be weighed at the very beginning of the study and then once/month for 6 months.
what would be a hypothesis for this experiment?
if people take the weight-loss drug, they will lose more weight.
the sugar pill will cause people to gain weight.
the sugar pill will cause people to lose weight.

does the data in the table support or refute the experimental hypothesis? why?
the data refutes the hypothesis because the new pill did not cause the experimental group to lose weight.
the data supports the hypothesis because the new pill caused the experimental group to lose weight.
the data refutes the hypothesis because the new pill did caused the experimental group to lose weight.
the data supports the hypothesis because the new pill did not cause the experimental group to lose weight.
define evolution
a genetic change in a population that occurs over time
individuals in a population that slowly adapt to change
individuals in a population copy behavior of other species in order to survive
a population dies off due to environmental changes
why is evolution a theory and not just a hypothesis?
because it has been proven
because it is supported by a massive amount of scientific evidence
because charles darwin is always right
because it has been proven through evidence collected
in developing the idea of evolution (which at the time was just a hypothesis), what two observations did darwin make in his study of organisms (during his travels on the Beagle)
A. genetic change B. gene flow
A. genetic drift
B. overproduction of offspring
A. heritable variation
B. overproduction of offspring
which of these evolutionary agents is most consistent at causing populations to become better suited (or adapted) to their environments over the course of generations?
gene flow
natural selection
genetic variation
genetic drift
which of these evolutionary agents is movement of individuals in and out of a population?
gene flow
natural selection
genetic variaton
genetic drift
which of these evolutionary agents is the change in frequency of an existing gene variant in the population due to random chance often caused by the bottleneck effect (natural disaster causing massive deduction in population)?
gene flow
natural selection
genetic variation
genetic drift
which statement best describes the evolution of pesticide resistance in a population of insects?
all insects in the population die after exposure to pesticide
insects observe behavior of other insects that survive pesticide application, and adjust their own behaviors to copy those of the survivors
individual members of the population slowly adapt to the presence of the chemical by striving to meet the new challenge
offspring of insects that are genetically resistant to the pesticide become more abundant as the susceptible insect die off
the five themes of biology
structure relates to function, evolution, life depends on the transfer and transformation of energy and matter, life depends on the flow of information, life depends on the interactions within and between systems
structure relates to fungi, evolution, life depends on the transformers, life depends on the flow of a river, life depends on the interactions between solar systems
structure relates to genetic drift, evolution, life depends on the gene pool, life depends on the molecular structure, life depends on the interactions between ecosystems
structure relates to function, evolution, life depends on the gene pool, life depends on the flow of energy, life depends on the interactions between ecosystems
the wall of your heart is primarily composed of cardiac muscle tissue. force is produced when muscle tissue contracts (or shortens) causing your blood to move through your blood vessels. consequently, your heart is a pump. what is the biology theme?
life depends on transfer and transformation of energy and matter
evolution
structure relates to function
life depends on the flow of information
this is the overriding theory of biology and accounts for the unity and diversity of life
evolution
structure relates to function
life depends on transfer and transformation of energy
life depends on interactions within and between systems
your cardiac muscle cells need energy to "pay for" muscle contraction. the (physiological) function of eating is to obtain chemical energy (food)
structure related to function
life depends on transfer and transformation of energy
life depends on the flow of information
life depends on interactions within and between systems
DNA is the "genetic code". scientific studies (in the ~1960's) "cracked the code" and led to life understanding of how DNA leads to the production of proteins
life depends on the transfer and transformation of energy and matter
evolution
life depends on the flow of information
life depends on interactions within and between systems
