Answer:
I believe the answer would be Heredity.
Explanation:
In the experiment, they painted yellow caterpillars green and placed them in a green environment amongst naturally green caterpillars. However, the paint only camouflaged the caterpillars into the environment, not reset their genes. So, the offspring of yellow caterpillars would most likely come out yellow (or green if it's in their genes), resulting in the yellow caterpillar offspring to be picked off more easily than the offspring of the green caterpillars.
(if that was confusing i completely apologize ;-;)
With Freezing.... the substance energy level decreases.
Freezing is endothermic and as such energy is lost to the environment
from the substance thus decreasing the energy level.
An environmental change than an animal must respond to could be a change in climate which affects humidity and temperature. If it could not adapt, it will die out and only the ones that could adapt will live on. This is called natural selection
Biogeochemical cycle, any of the natural pathways by which essential elements of living matter are circulated. The term biogeochemical is a contraction that refers to the consideration of the biological, geological, and chemical aspects of each cycle.
Cells are the basic unit of life. Atoms make up molecules. molecules make up cells. cells make up tissues. tissues make up organs. organs make up organ systems and organ systems make up the human body. therefore, without cells, there is no life.
