Fungi are eukaryotic organisms that comprise one of the kingdoms of life.<span> Most fungi are multicellular. As eukaryotic organisms, fungi possess cells with organelles, which are structures surrounded by membrane.
hope this helps
thus, mushroom fungus is eukaryotic!!!</span>

Antibodies are produced when the body is exposed to antigens.
During an initial encounter with a foreign antigen, the body's immune system namely the adaptive arm of the immune system, produces memory cells, a group of special lymphocytes that retain and store memory of the antigen.
On a second encounter with the same kind of antigen, the immune system "remembers" the antigen and mounts a rapid, specific and vigorous immune response against the antigen. This response includes the production of massive amounts of antibodies very specific to the antigen.
The antibodies effectively neutralize the antigen and facilitate its destruction.
A Nerve electrical impulse only travels in one direction. There are several reasons nerve impulses only travel in one direction. The most important is synaptic transport.
In order for a "nerve impulse" to pass from cell to cell, it must cross synaptic junctions. The nerve cells are lined up head to tail all the way down a nerve track, and are not connected, but have tiny gaps between them and the next cell. These tiny gaps are called synapses.
When you get a nerve firing, you have probably heard that it is an electrical impulse that carries the signal. This is true, but it is not electrical in the same way your wall outlet works. This is electrochemical energy. Neurotransmitters are molecules that fit like a lock and key into a specific receptor. The receptor is located on the next cell in the line. When the neurotransmitter hits the receptor on the next cell in line, it signals that cell to begin a firing as well.
This will continue all the way down the length of the nerve track. In a nutshell, a nerve firing results in a chain reaction down the nerve cell's axon, or stemlike section. Sodium (Na+) ions flow in, potassium (K+) ions flow out, and we get an electrochemical gradient flowing down the length of the cell. You can think of it as a line of gunpowder that someone lit, with the flame traveling down the length of it. Common electrical power is more like a hose full of water, and when you put pressure on one end, the water shoots out the other.
Therefore, nerve impulses cannot travel in the opposite direction, because nerve cells only have neurotransmitter storage vesicles going one way, and receptors in one place.
he left and right hemispheres are connected by the cerebral commissures. Thus, the correct option is C.
<h3>
What is cerebral commissures?</h3>
Three tracts of nerve fibers or axons connect the right and left cerebral hemispheres, and these are referred to as commissures cerebral.
The corpus callosum, anterior commissure, and posterior commissure are three transverse nerve fiber bundles that connect homologous parts of each hemisphere.
The corpus callosum, also known as the great cerebral commissure, is the largest, connecting the majority of the cerebral hemispheres and allowing the cerebral cortex to function as a whole.
