Disease Questions and Answers (Q&A)

Vertigo and Dizziness can be used interchangeably when describing the sensation of instability or a feeling of lightheadedness. Although the symptoms of vertigo and Dizziness may seem very similar in some ways, the truth is both terms are not totally the same. Dizziness is just a term that describes the sensation of imbalance, confusion, etc. At times, you just find yourself on the verge of losing your stand just because you have stayed so long on the ground.

Also, you can just be looking at some things while standing, and suddenly feel like you want to fall. The two examples are a better explanation of dizziness means. Vertigo, on the other hand, is also a term that describes the sensation of imbalance, lightheadedness, etc. But before this, there is always a spinning or whirling sensation in your head, which will definitely lead to Dizziness. This spinning sensation can also cause disorientation. However, vertigo and Dizziness are most times caused by a sudden reduction in the blood supply to the brain.

Hallucinations and Delusions are both symptoms of schizophrenia, which is a sure indication of a misplaced perception of what reality is. Although both words are used to mean the same thing, they differ in meaning and in processes that lead to their occurrence Hallucinations occur as a result of fatigue, stress, drugs, or mental weaknesses, which causes the brain to remember some thoughts and perceptions already stored. Therefore hallucinations occur at conscious periods.

Delusion, on the other hand, is a usual display of multiple personalities at the same time, which causes swings in behavior and disorders. It also means a strong conviction in the unimaginable or impossible regardless of real proofs that disapprove those conceived imaginations of the Unreal and impossible. Both hallucinations and delusions are an end result of deep stress, depression, and severe anxiety. There are medications used in tackling hallucination when it has stayed for on a long term basis.

The inherited trait is something that you have gotten because of the genes of your family members. For example, getting the same eye shape as your mother’s mean that you have an inherited trait. An acquired trait is something that you may get because of your upbringing. For example, you may start learning how to play a new instrument because you were given a chance to learn how to play that instrument.


Learning how to play is an acquired trait although some people are naturally good at it. They learn how to play instruments with a lot less effort. Your natural hair color is an inherited trait, if you would check your family members, chances are, they will have the same hair color as yours.

HDL is the acronym for High-Density Lipoprotein. It is also commonly referred to as “good cholesterol” because it gets rid of excess cholesterol in the body by transporting cholesterol to the liver to be expelled by the body. Try to keep the number of HDL in the body on the high side because the higher the number, is the better. LDL, on the other hand, is the acronym for Low-Density Lipoprotein; it is also called “bad cholesterol” because it transports cholesterol to the blood, where it can clog the blood vessel wall.

This leads to building up plaques, which can cause atherosclerosis and further lead to complications such as stroke, hypertension, and heart attack. Try to keep LDL levels on the low side because of the higher the level, the more the risk of having certain health conditions.

A goitre is one of the most common thyroid disorders. In this disease, the thyroid gland causes our neck to swell and become enlarged. However, they are harmless.

Goitre mainly occurs when we eat foods such as soybeans, rutabaga, cabbage, and peanuts. The chances of suffering from goitre become higher as there are goitre-promoting foods. Our health-diet plays the most important role in causing or preventing a goitre. Below, I have enlisted some of the ways (in no particular order) through which you can prevent goitre:

  • Smoking can lessen iodine absorption in your body. So, it’s better to quit smoking as soon as possible.

  • Under and over-consumption of iodine in your diet can also lead to goitre. Hence, it’s your responsibility to take an appropriate amount of iodine in your diet.

  • Try to avoid radiation therapy.

  • Always eat a healthy and balanced diet.

The correct answer to this question is C, Secreted slime layer. Pili are appendages, which resemble hair. They can be found on archaea and bacteria. The word pili can also refer to the composition of pilin proteins. These proteins are oligomeric. Many bacteria and viruses use the pili as a way to attach onto and reproduce. Pili are very fragile, and because of this, they are always replaced. There are various types of pili. One is conjugative pili, which is how DNA is transferred from many bacteria. There are also Type IV pili, which helps generate motile forces.

Parasites and Pathogens are diseases causing agents that are dangerous to the host organism. They are specific to the host and tend to multiply at a very high rate. The following are the striking differences between pathogens and parasites: a. MEANING: Pathogens are disease-causing agents that cause sickness to their host while parasites are organisms that live in/on another organism called the "host organism" and benefit from the organism at the host's expense. b. LEVEL OF ORGANISATION: Pathogens are eukaryotic organisms. Eukaryotes are the organisms whose cells have a nucleus with their membranes.


In contrast, Parasites are prokaryotic organisms except for fungi. A prokaryote is a unicellular organism that does not have a membrane-bound nucleus and mitochondria. c. VISIBILITY: Parasites are microscopic organisms that are visible to the naked eye while pathogens can either be macroscopic or microscopic. d. PATHOLOGY: Parasites do not cause infectious diseases in the host organism, but pathogens are responsible for creating diseases in the host organism.
