A plant biologist discovers a new species of plant in the ashes of a recent forest fire along the sides of a steep mountain range. It is fall, and temperatures are dropping below freezing. The biologist cannot stay in the field to observe the plant. What can he infer about the plant’s reproductive strategy, based on his recent observations?

Based on the observations, the plant likely reproduces by dropping a pod of some sort (such as a cone) and the heat of the fire allows the pod to open up and drop the seeds. This is called pyrophytic reproduction.

Explanation:

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 .
