Reproduction ensures ongoing generations of both bacteria and frogs.

Some toads that live in a hot environment bury themselves in the soil during the day. What characteristic of living things does this behavior represent?

Convert:
10cm=_______mm

The energy that drives metabolism in animals comes from water.

Cells working toward a common purpose make up what?

Scientific hypotheses are most often tested by the process of experimenting.

Erika heard that plants compete for space. She decided to test this idea. She bought some flower seeds and some potting soil. Into each of five identical plastic cups she put the same amount of soil. In the first cup she planted 2 seeds, in the second cup she planted 4 seeds, in the third cup 8 seeds, and in the fourth cup she planted 16 seeds. In the last cup she planted 32 seeds. She gave all the plants the same amount of water, and kept them together in a sunny area. After 30 days, she observed the cups to see which contained plants that looked the healthiest.

What was Erika trying to find out?

Life begins at what level?

See board figure B: round to nearest 100th. Calculate V.

Scientific thinking can be used
