Mildew is a fungus that grows in wet areas and can slowly grow from microscopic to large stains in showers and sinks. researchers are studying different sprays that could be used to slow down the growth of mildew. they set up different showers that are exactly the same and expose them each to water with the same microscopic amount of mildew. they then spray some showers with mildew-preventing sprays and observe how fast mildew grows over time. which shower would most likely be the control group in this study? a. the shower sprayed with many test sprays b. the shower not exposed to any mildew at all c. the shower not sprayed with any mildew-preventing spray d. the shower sprayed with a test spray that is already known to work

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.

The negative impacts of nonnative species generally outweigh the positive impacts

What molecules will be best used to compare different species with the exact same sequence of amino acids? why would two species have the same protein even if the molecules in question is different? (hint: transcription to translation to protein).
