Dendrites and axons.
Dendrites and axons are extensions/fibers in nerve cells that either recive or send information to neurons respectively.

Answer;
- 100
Researchers have identified about 100 substances that are made in our body and brain that act as neurotransmitters.
Explanation;
-Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons, where they stimulate the muscle fibers.
-Neurotransmitters enable neurotransmission, which is the process by which signaling molecules (neurotransmitters) are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and activate the receptors on the dendrites of another neuron.
Answer:
A closed system is a physical system that does not allow transfer of matter in or out of the system, though, in different contexts, such as physics, chemistry or engineering, the transfer of energy is or is not allowed.
Answer:
The phloem is responsible for transporting food from leaves to other parts of the plant.
The transport of pholem is bidirectional and changes the movement of particles according to the season. Generally, the transportation occurs in the direction of the source to sink but in spring season the direction is opposite that is from sink to source because the source and sink are n opposite sides. So in spring season, the stem tubers are sources and the growing leaves are sinks.
The main functions of Mitosis are growth and repair.
Cells must perform this to where they can grow or repair. Some cells you cannot regrow nor repair because they are already fully mature, you'll just halve to take care of them.
