neurotransmitters
What chemical is released by the endocrine system?
hormone
neurons
nerves
neurotransmitters
In order for a cell to be a target cell for a hormone it has to

Two primary agents of cellular communication are
chemicals made by blood cells and simple sugars.
hormones and carbohydrates.
hormones and chemicals made by nerve cells.
enzymes and starches.
Feedback mechanisms are processes that
maintain a steady internal state
maintain an imbalance in organ systems
maintain a steady external state
maintain a hot temperature in the body only
The diagram represents an interaction between parts of an organism.
The secreting cells are gland cells. Therefore, the blue circles in this diagram best represents
DNA molecules
receptors molecules
starch molecules
hormone molecules
Select the two causes of muscle fatigue:
too much oxygen in cells
not adequate (enough) oxygen in cells
buildup of metabolic waste in cells
buildup of waste like glucose in cells
Plant cells in a tube would float to the surface if exposed to sunlight because they produce
oxygen, a gas
carbon dioxide, a gas
glucose, a molecule
ATP, a molecule
The diagram represents an activity that occurs in the human body. It best illustrates
