Question: Which of the options below is an example of a transmissible disease?

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \\ \\ \star \: \sf{Obesity} \\ \\ \star\sf \: {Tooth \: decay} \\ \\ \star \: \sf{Cholera} \\ \\ \star \: \sf{Rickets} \end{array}}\end{gathered}$

Solution: From the following an example of a transmissible disease is Cholera.

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \: Answer \\ \\ \star \: \sf{Obesity} \\ \\ \star\sf \: {Tooth \: decay} \\ \\ \star \: \sf{Cholera \: \boxed{\checkmark}} \\ \\ \star \: \sf{Rickets} \end{array}}\end{gathered}$

Explanations:

▶️ Why I am saying that Cholera is transmissible disease except of Obesity, Tooth decay and Ricket? Have you ever listen that ah! I have tooth decay, it very paining. When a person have tooth decay and he is talking with anyone else get the same tooth decay, seriously? No! Ya then it's not a transmissible diseases.

▶️ Have you ever listened that if someone have obesity means he is obese then the other person who is near him or talking with him be obese, seriously? No! Ya then it's not a transmissible diseases too.

▶️ You know that ricket is that disease that is due to deficiency of vitamin in our body that's why it is not a transmissible diseases too.

▶️ Now cholera is a single option left that we have, ya true it is transmissible diseases it's because it is spread by pathogen that is bacteria. And it's mode kf transmission is water we drink kr food we eat.

★ Heya! We sre talking again and again that transmissible disease...transmissible disease but what is transmissible disease?

• Another name for transmissible disease are communicable disease or infectious disease. It is done by pathogens!

Question: How is propagation of ginger generally done?

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \\ \\ \star \: \sf{Seed} \\ \\ \star\sf \: {Root} \\ \\ \star \: \sf{Stem} \\ \\ \star \: \sf{Leaf} \end{array}}\end{gathered}$

Answer: Propagation of ginger generally done by Stem.

$\begin{gathered}\boxed{\begin{array}{c}\\ \bf \bigstar \: Multiple \: Choice \: Question \\ \\ \star \: \sf{Seed} \\ \\ \star\sf \: {Root} \\ \\ \star \: \sf{Stem \: \boxed{\checkmark}} \\ \\ \star \: \sf{Leaf} \end{array}}\end{gathered}$

Explanations:

▶️ Vegetative reproduction by stem take place in a number of plants like potatoes, gingers, sugarcane, onion, banana, mint, grasses etc. Basically potato is an underground Stem Tuber.

• Similarly when we are growing ginger then same vegetative reproduction takes place. Ginger is also a modified swollen underground step and it is known as rhizome. It contains stored food material.
