Answer:
here is your answer
Explanation:
Global warming is primarily caused by emissions of too much carbon dioxide (CO2) and other heat-trapping gases into the atmosphere when we burn fossil fuels to generate electricity, drive our cars, and power our lives. Thus, as we continue to emit these gases, their atmospheric concentrations build up over time
Answer: Endocrine
A chemical signal produced in the pituitary gland at the base of the brain binds to a receptor on liver cells. This signal would be classified as an endocrine signal.
Explanation:
An endocrine signal is produced by a cell that targets a distant cell through the bloodstream.
Hence, a endocrine signal (carried by hormones) produced at the base of the brain (usually an endocrine gland) travels through the bloodstream to the target cell and binds to a receptor on the liver, and then exerts its function.
