Answer:
If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.
Explanation:
Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.
- <u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
- An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.
An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.
On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.
The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution. Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."
The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.
Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.
That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.
<u>About lipase enzymes</u>:
- It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.
- The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.
- It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.
- They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.
Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.
