they must be unicellular and microscopic and they must be eukaryotic
Answer:
4. The kinetics for the enzymatic processes of microorganisms responsible for decomposition are slowed.
Explanation:
Generally most enzymes work best at optimum temperature of 35-40 degree centigrade, This is because enzymes are proteins, and proteins are sensitive to temperature.
Therefore at low temperature of refrigeration below -18 degree, enzymatic processes of microorganisms need for biochemical activities, oxidative activities and growth are slowdown(thus microorganism population is reduced) . Microorganisms are inactive. Therefore the rate of food decomposition is slowed down,which prolonged nutritional value of the food.
Although the total distance the impulse travels in the reflex arc is less than 3 meters. the time taken is more than 0.04 seconds and the time taken is more than expected because of Synapses or due to gaps between neurons.
Diagram displays the whole reflex arcs from the tip of the finger to the spinal cord and then back out to a closer muscle, possibly in the forearm or the arm. Because the signal doesn't have to go all the way back to the finger, the total distance is less than 3 meters. Considering that it just travels back a portion of the way, less than 3 meters, it takes. Let's see, it takes more than twice as long, therefore the query makes us think about why the delay. Where is the hold-up what is happening there, and the key to this is that the gray matter of the spinal cord doesn't truly contain mylin, despite the fact that we said it- accelerates electrical conduction through the axon in the nerves of the extremities. Mylin has a whitish color, which contributes to the white matter's appearance of whitishness. Thus, the electrical signal becomes slower.

Answer;
-Dendrites receive chemical signals.
-When more excitatory than inhibitory signals are received, the cell depolarizes.
-An action potential is set off and travels through the cell and down the axon.
-The action potential excites the terminal buttons to release their chemicals into the synaptic cleft.
Explanation;
-The electrical signal that passes along the axon and subsequently causes the release of chemicals from the terminal buttons
. Chemical signals (excitatory and inhibitory signals.
-Positive sodium pours into the breach, Action potential propagates along the axon, after firing returns to its slightly negative resting state.
-An action potential can be generated if the amount of excitatory input can raise the membrane potential to -55 mV. This then floods the cell with sodium ions and raises the membrane potential. When it reaches a certain point (about +30 mV), the sodium ion channels close and the potassium ion channels open. This drops the membrane potential back down.
