Answer:
explanation below
Explanation:
The control group would be the biodiversity of the trees without the fire
The control group in the experiment would center on the biodiversity of the trees without the fire. Ideally, both the control group and the experimental groups are usually identical in every way except that the experimental group would receive the treatment that is believed to have an effect on the biodiversity of trees.

Unlike carbon-based fuels like coal, natural gas, and petroleum, nuclear energy does not release greenhouse gases into the atmosphere. Therefore it does not contribute to global warming.
Explanation:
Nonetheless, nuclear energy is not widely adopted for energy because of its safety concerns. Fission energy is harmful to the environment because of nuclear waste it generates. How this nuclear waste is stored is very important because leakage can lead to contamination of an environs with lethal radioactive elements.

Answer:
Cells in a large multicellular organism communicate with each other by chemical signals. These signals are passed from one cell to another. To receive and respond to a chemical signal, a cell must have a <u><em>receptor</em></u> for that chemical.
Explanation:
To generate a physiological response, all cells in the body have special proteins called receptors. These receptors are involved in detecting a chemical signal and generating a response. The receptors are specific for different kind of chemical signals. For example, a dopamine receptor will bind a dopamine molecule whereas an insulin receptor will be able to bind an insulin molecule. Apart from chemical signals, some cells might also respond to mechanical signals.
