Plant responses to an environmental change by: increase in ions and organic compounds in xylem and phoem, form thick, waxy scales over leaf buds, and leaves drop off.
what kind of ecosystems would be most beneficial to the plants with the above changes?
1. ecosystems with great variation in rainfall throughout the year.
2. temperate ecosystem with cold winters
3. ecosystems near the equator with consistent conditions year round
4. desert ecosystem receiving occasional rain

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

where is the scientific experiment?

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 .
