Mice are common subjects for medical experiments because the responses of their body systems are very similar to human responses. A scientist is planning an experiment to investigate homeostasis in mice. The steps of the procedure are listed below. The procedure involves mice that have not eaten for 24 hours.

1. Divide the mice into two groups, labeled A and B.

2. Take a blood sample from each mouse. Measure the levels of blood glucose and insulin.

3. Feed the mice in Group A a high-sugar food, such as candy bars. Do not feed the mice in Group B.

4. Repeat Step 2 of the procedure.

5. Repeat Step 2 again, every 5 minutes for 1 hour.

After the mice in Group A are fed, which of these events helps to maintain homeostasis in the bodies of the mice?

Which describes how weathering and erosion are different? weathering is caused by water. erosion is caused by wind and ice. erosion transports sediments. weathering is a natural process.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection

Land conservation is a worldwide priority. there are several methods to prevent the loss of land due to a variety of reasons. which method is not a way to conserve land? a) sea walls b) rainwater harvesting c) limits on clear cuts of forests d) cut and burn methods of clearing land
