Answer:
True
Explanation:
Natural pollutants can be dirt that has become airborne. Man-made is can be numerous things from smoke to exhaust from cars.
The myelination of axons or the presence of the myelin sheath regulates the conduction velocity of the nerve impulses by acting as an insulator to the nerve fibers. The spaces or gaps between each myelin sheath are called the nodes of Ranvier and the impulse go from one node to another. This phenomenon is called saltatory conduction.
Nice to know: The myelin sheath in the central nervous system is provided by cells called oligodendrocytes. On the other hand, the myelin sheath in the peripheral nervous system is provided by cells called the Schwann cells.
All cells come from pre-existing cells
<span>The dissecting microscope would help the most in this case. This object does not use high levels of magnification, so it would assist with larger insects, which do not need to be magnified much to be seen well. In addition, the use of light reflected from the surface of the object would be of more use than trying to pass light through the object, which is more typical of a compound light microscope.</span>
The effect of beneficial microbes of normal biota against invading microbes is called microbial antagonism.
<h3>What is the name of the effect of beneficial microbes of normal biota against invading microbes?</h3>
- Living entities that are too small to be seen by the normal eye are referred to as microbes or microorganisms. They primarily consist of bacteria and fungus, which are single-celled organisms.
- The conflict between microbial species over food sources and territory is known as microbial antagonism.
- The normal bacterial flora of the body acts as a defence against pathogens through microbial conflict. As a result, if one organism outcompetes another, the organism that was unable to flourish in the environment will be inhibited.
- Since many of the bacteria that live in our intestines are antagonistic to pathogens, antagonism may be fueled by mechanisms like the manufacture of antibiotics or competition, and it frequently aids people in avoiding intestinal illness.
