Homework self assessment:
design an experiment to determine if a solution containing ground-up goldenrod plants has an effect on the growth of radis
seedlings.
7. question: does a solution containing ground-up goldenrod plants have an effect on the growth of radish seedlings?
8. hypothesis: if a is added, then the growth of radish seedlings will increase/decrease choose
9. experiment:
experimental group
control group
-
grow radish seedlings
-
grow radish seedlings
} make sure everything else is
constant: # of seedlings, amount of
water & sunlight, type of soil, etc.
-
no solution
add solution containing
ground-up goldenrod plants
iv: solution containing ground-up goldenrod plants
dv: growth of radish seedlings (data? measure height of radish seedlings)

Graphs you see question 5 options: the change in data over time the relationship between different dependent variables the relationship between the independent variable and the dependent variable/s the relationship between different independent variables

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
