Kari is testing the hypothesis that plants rely on photosynthesis to grow. she conducts an experiment in which she observes the sprouting and growth of bean seeds. the beans are raised either in sunlight or darkness. she records her observations in a data table. which statements from kari’s records convey qualitative data, and not quantitative data? choose all that apply. a. the beans in the control group have a white spot on day 2. b. the beans in the control group have 1.0 centimeter sprouts on day 3. c. the beans in the control group feel soft on day 2. d. the beans of both groups appear equally green and healthy on day 1.

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.

When proteins are being produced by a cell, scientist say that the genes are question 2 options: activated turned off replicated deactivated
