An ice cube, a glass of cold water, and a swimming pool are each exposed to the samme amount of sunlight on a hot day. after five minutes, the ice cube is melted and the cold drink is two degrees warmer, but the temperature of the swimming pool remains unchanged. what is the best explanation for these observations?
a. the ice cube has a higher heat capacity than the glass of water and the pool
b. the ice cube has a lower heat capacity than the glass of water and the pool
c. the ice cube and the glass of water have higher heat capacities than the swimming pool

Compare and contrast nutrient limitation in soil vs. nutrient limitation in aquatic ecosystems

Each pair of clay balls represents two planetesimals. if each planetesimal is composed of the same material and is separated he the same distance, which pair experiences the frayed gravitational attraction?

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.
