The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.
Answer:
Finally, the chemical messenger is taken back into the presynaptic neuron, ready to be used again. As levels of the neurotransmitter in the synapse decrease, the stimulation of the postsynaptic nerve ends.
Explanation:
The synapse is the space between two neurons. Through this space, neurons communicate.
An action potential causes the release of neurotransmitters from the presynaptic neuron; if there are enough of these specific neurotransmitters to bind to receptors on the postsynaptic neuron, they do and an action potential is now generated on this neuron.
This communication between two neurons must end once it's happened. In order for it to end, the synapse must be free of neurotransmitters. One mechanism to do so is for the neurotransmitters to be taken back into the presynaptic neuron.
Answer:
Brain consists of three major parts- cerebrum, cerebellum and the brain-stem.
Explanation:
Functions-
A) Cerebellum- helps body move more slow.
B) Cerebrum- Largest part of the brain consists of right and left half.
C) Hypothalamus- Regulates eating and drinking and body temperature.
D) Medulla- Controls basic life functions like heart rate.
E) Meninges- membranes that surround and protect the brain and spinal cord.
F) Midbrain- Plays a role in the maintenance of consciousness.
G) Pons-Controls movement of the eye and helps in auditory and visual processing
H) Thalamus-Passes signals from the spinal cord to the brain and controls breathing
I) Frontal lobe- Reasoning of judgement.
J) Partietal lobe- sense of touch of vibration.
K) Temporal lobe- Auditory processing and word meaning.
L) Occipital lobe- vision.
Shunting is blood movement across the chambers of the heart.
I’m pretty sure it’s catabolic reactions.
