Answer:
The receptors on the postsynaptic membrane (dendrites) of a neuron receive(s) the transmitter released by other neurons.
Explanation:
Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites and an axon. The <u>dendrites </u>are cytoplasmic extensions that <u>receive stimuli from other cells</u>. The axon is a long formation capable of conducting the electrochemical signals.
Every neuron forms connections with other neurons. These connections are known as synapsis. As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area of the other neuron and binds to its <u>receptors in the postsynaptic membrane,</u> located in dendrites of the other neuron. This receptor is a protein structure that triggers an answer. The binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it. As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space.
I would go to the website, that will help a ton! I have done this assignment.
Answer:
A paleontologist is a scientist who studies the history of life on Earth through the fossil record. One example is dinosaur fossils. Paleontologists will examine fossilized droppings in order to see what the dinosaurs ate! Hope this helps! A scientist who studies plants is called a Botanist. A scientist who studies living things is a biologist, and a scientist who studies the ocean is called a oceanographer.
C is the answer. Happy learning!
Answer:
Relative velocity simply means velocity relative to a certain observe point, in this case, the river shore.
This is a type of complex movement; a boat is moving with a certain velocity, let's say 8 m/s. However, the river this boat moves on also has its velocity, let's say 2 m/s. Since the shore isn't moving, the velocity of the boat relative to the shore will be simple resultant velocity of the boat's and the river's velocities.
Let's illustrate this with two examples:
1) if the boat is moving downstream both are moving in the same direction, so the resultant will be 8 m/s + 2 m/s = 10 m/s.
So, any spectator looking at the boat from the shore will think its velocity is 10 m/s, when in reality it's 8 m/s.
2) if the boat is moving upstream, these two velocities have opposite directions, so the resultant will be 8 - 2 = 6 m/s
So, as a short summary, relative speed is an object's speed in regard to another chosen referent point.
Remember, the principal product of the photosynthesis is the molecular oxygen and sugars; that means that a reduction in photosynthesizing plants will result in a decrease in dissolve oxygen.
