How does the structure of each type of neuron relate to its function in the nervous system?
Sonbull [250]

Answer:

Motor neurons:

A. Function:

It relay messages coming from the brain or spinal cord to the muscles or organs.

B. Structure:

●Presence of long axons due to long distances the signals have to travel to the muscle its stimulating.

●It's myelinated, to assist the signal in travelling long distances as soon as possible.

Sensory neurons:

A. Function: its sensory receptors respond to stimuli by converting it into an electrical signal to the brain or spinal cord.

B. Structure:

●Presence of long dendrites / axons

● its myelinated

●since it's found in the middle of the neuron it forms ganglia that unites in the spinal cord and aid in involuntary reflexes.

Interneurons:

Structure:

● shorter than motor or sensory neurons

● has branches, a lot of branches consisting of axons and dendrites off the cell body to enable multiple simultaneous between neurons

● It's body is partially myelinated.

●occurs in large clusters of neurons to compensate for its partial myelination to speed up the signal

Why are most of the stomata on the bottom of the leaf
larisa86 [58]

Answer: Stomata plays very crucial roles in plants. During photosynthesis, gas exchange takes place via the stomata. Water also evaporates from plants through the stomata. In plants, most of the stomata are usually on the bottom of the leaf IN ORDER TO PREVENT EXCESSIVE LOSS OF WATER.

During the day, the sunlight falls on the leaf directly and draws water from the plants. Locating the stomata at the underside of the leave reduces the amount of water that can be lost through excessive evaporation. Also, locating the stomata on the underside of leaves prevent  the leaves from taking in too much water during rainfall.

Describe the effects of the various antibiotic drugs you used. Were they all equally effective at controlling bacterial growth?
Kipish [7]

Answer:

Basically, most   antibiotic drugs  are not  effective in controlling bacterial growth. The potency of any antibiotic drugs is a measure of the magnitude of  diameter of the  bacterial growth . <u>This is because the diameter   is the measurement of the bacterial growth around the antibiotic drugs used to control it multiplication, and therefore a  measure  of how effective  it  can controls the population</u> Thus a small diameter around the antibiotic agent is a proof that it suppressed the growth effectively and can effectively be used to control  the bacteria, While  a large diameter is an indication of low effectiveness of the drug.

Based on this analogy, penicillin with wide usage for control  of bacteria growth  with  diameter of 3mm, is the most effective antibiotic drugs.However, Erythromycin which is also widely used control growth with diameter of 5mm  or 6mm depending on   type of bacterial.

Therefore, the least 3mm  diameter presented by penicillin is an indication that , antibiotic drugs  are not effective enough, and further research need to be done to control growth of bacteria and therefore its   pathogenic  effects.
