Ascientist observes changes in a population of slow-moving animals over time. she hypothesizes that the population may be decreasing. to test her hypothesis, she will analyze the population using the / blank / method. she finds that the population of this species is significantly decreasing. if this trend does not change, this species could become / blank /

The correct answer is blank1: quadrant sampling, and blank2: endangered.

Explanation:

A scientist needs to test her hypothesis she needs to perform an experiment or test and for a slow-moving animal (like snail or earthworm) quadratic sampling is a perfect method. The quadrate method uses a closed plot of land to find the vegetation of plant or population percentage of animals present in that land.

A decreasing population of animal could be endangered if the trend will not change.

Thus, The correct answer is blank1: quadrant sampling, and blank2: endangered.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
