okay even just that was very helpful thank you!

Answer 4

In the kidneys, both useful substances and wastes are removed from the blood by
D. filtration.

When an impulse reaches the end of a neuron, it triggers the release of
A. neurotransmitters.
The neurotransmitters are released from the axon and cross the synapse to be picked up by the dendrites on the other end. Different neurotransmitters have different effects. Some will trigger then next neuron to fire, and some will inhibit it, making it harder to trigger.

Which of the following choices best describes dopamine?
Treats circulation problems caused by heart attack, heart failure, kidney failure, low blood pressure, or surgery.
C. A receptor molecule that is found on neurons.


What is the function of the central nervous system?
The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components.
D. to process information and form a response

Answer 5

I hope this helps, tell me how it goes. (:

Answer 6

1 (kidneys): D
2 (impulse): A
3 (dopamine): I’d go with A(!), since it’s a neurotransmitter, not a drug (B), not a receptor (C) and it doesn’t exclusively stimulate cells (D) but can also inhibit them
4 (CNS): D
5 (saliva): A
6 (taste): A
