Question: Which of the following diseases listed below are not caused by infectious pathogens?

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \\ \\ \star \: \sf{Coronary \: heart \: diseases} \\ \\ \star\sf \: {Cholera} \\ \\ \star \: \sf{AIDS} \\ \\ \star \: \sf{Scurvy} \end{array}}\end{gathered}$

Solution: Option 1 and 4 that is Coronary Heart Disease and Scurvy are correct means Option B

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \: Solution \\ \\ \star \: \sf{2 \: only} \\ \\ \star\sf \: {1 \: and \: 4 \: \boxed{\checkmark}} \\ \\ \star \: \sf{2 \: and \: 3} \\ \\ \star \: \sf{3 \: and \: 4} \end{array}}\end{gathered}$

Reasons:

▶️ As we know that Scurvy is caused by the deficiency of vitamin C in our body. That's why this line satisfy this equation that option B is correct. But what about coronary heart disease and others?

▶️ AIDS disease and Cholera are those disease which are caused by pathogens. Pathogens are those microorganisms which can cause diseases in human beings. These enter in our body through the water we drink, air we breathe and food we eat.

▶️ AIDS stands for Acquired immunodeficiency syndrome. It is not caused by any pathogens! It's reason is HIV infection. HIV stands for Human immunodeficiency virus. It is happen from blood, semen or else. And the another important reason for it is that if anyone do sēx with that person who is infected by HIV.

▶️ Coronary Heart Disease (CHD) is not caused by infectious pathogens.

Question: Where does fertilization in human beings take place?

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \\ \\ \star \: \sf{Fallopian \: tube} \\ \\ \star\sf \: {Uterus} \\ \\ \star \: \sf{Testes} \\ \\ \star \: \sf{Ovary} \end{array}}\end{gathered}$

Solution: Option A that is Fallopian tube is absolutely correct answer.

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \: Solution \\ \\ \star \: \sf{Fallopian \: tube \: \boxed{\checkmark}} \\ \\ \star\sf \: {Uterus} \\ \\ \star \: \sf{Testes} \\ \\ \star \: \sf{Ovary} \end{array}}\end{gathered}$

Reason:

▶️ Fertilization in human beings take place in Fallopian tube, it is that tube which links an ovary to the uterus. Embryo start growing if the fertilized egg go successfully through fallopian tube. And it is the part of female reproductive organ.

▶️ And the testes, uterus and ovary are reproductive organs.

• Scurvy arises where there is a deficiency in Vitamin C intake.

• It causes Delay in healing of wounds and fractures in bones.

• It can be avoided by taking in Vitamin C in sufficient quantities.

• Why not AIDS and Cholera?

• AIDS (Acquired Immuno Deficiency Syndrome) is a condition where the pathogens attack the immune system of our body making us vulnerable to diseases and ultimately causing death.

• There is no cure for HIV - AIDS.

• Cholera is condition where pathogens (bacteria) enter into our body through water and disturb the normal functioning of our body by causing nausea, diarrhoea, etc.

• It can be cured by medical attention.
