<span>The
difference in structure of the antennae and antennules is their size or length.
Antennae are long sensory organs while antennules are short or small sensory organs. These
organs are connected to the head of an insect, crab, or other animal and they
are used for taste, balance, smell, touch, air motion and vibration</span>
Answer:
1. In order to fix the bacterial to the slide;
<u>so that it will not be lost during the staining procedure.</u>
<u>so that false impression or result will not be given by the bacteria in water,</u>
<u>Distilled water is used to prevent contamination with impurities e,g metals ions and crystals</u>.
Explanation.
In smear preparation; the bacterial cells should also be well dispersed,so that they do not clumped together to form' big glob'.(large round masses) The later affect clear field view of the bacterial mophology, affected staining, and therefore gives inaccurate results,
Fixing to the slide also affects the morphology of bacterial cells, through shrinking in size, which can lead to loss of structural characteristics and extra-cellular matrixes,
Below 50 meters, the ice now behaves in a ductile manner rather than a brittle manner, meaning it will stretch and fold under stress rather than fracturing.

Multiple sclerosis develops when nerve cells in the brain and spinal cord lose the insulating mylien sheaths that surround them.This can happen anywhere in the CNS and is random.
Symptoms are Muscle weakness, loss of sensory input from the skin and other areas, poor vision and mental problems due to the loss of the protective mylien the neurons stop conducting the impulses and hence there is a loss of functions controlled by the areas of the CNS concerned.
Hope this helps! :)
