Answer:
a. An intoxication
Explanation:
Intoxication occurs when a toxic substance comes into contact with an organism and causes a number of adverse effects, affecting its homeostasis, disrupting the organic balance.
When a person or animal eats a food contaminated mainly with bacteria, a number of unpleasant symptoms are triggered by the body due to the poisoning caused by some substance released by the bacteria. Usually people associate the infection with spoiled / spoiled foods, but often they can eat contaminated, good-looking foods.
This is the case of intoxication caused by V. parahavmolyticus. Food contaminated by this bacterium has no change in color, taste or smell. When someone eats food contaminated with V. parahavmolyticus, they ingest a toxin produced by this bacterium. This illness is referred to as food intoxication.
Answer: FALSE
Explanation:
The plasma membrane has both Na –K channels across it walls. They are membrane transport proteins which hydrolyse ATP s for the active transport mechanisms for transport of sodium and potassium ions across the plasma membranes .
Naturally,there are more potassium ion channels than sodium channels in plasma membrane; potassium is also extracellular while sodium is extracellular
Therefore ,when some potassium ions diffused into the Axoplasm, from the extracellular medium;;some potassium ions still move out BACK into the extracellular environments. Not all potassium are restricted from leaving .
This leakage occurs because of more available potassium ions channels than sodium ions, and higher number of available potassium ions
Thus the answer is FALSE
the ratio of diffusion <u>is 3 sodium out to 2 potassium in </u>

Answer;
D. The immigration of the population is greater than the emigration.
Explanation;
A population consists of all the organisms of a given species that live in a particular area.
Populations change based on the births, deaths, immigrations, and emigrations that occur within the group. These additions and subtractions all affect population size, but do so in different ways.
Immigration is the migration of individuals into a population. Emigration, which is the migration of individuals out of a population, decreases the size of the given population.
The correct option is IPSILATERAL. The anatomical path of a reflex is called reflex arc. An ipsilateral reflex arc is one in which the motor output occur on the same side of the body where the stimulus is detected. Apart from ipsilateral reflex arc, there are other two types, which are conlateral and intersegmental reflex arc.
