Answer 2

Answer:

THE ANSWER TO THIS QUESTIONS ARE

A) CARBON MONOXIDE

B) PLASTIC

C) BIG

D) SUPERVISED

Explanation:

A) Carbon Monoxide is produced when  soft coal or wood is burnt.

Carbon Monoxide is a very dangerous chemical

• It can combine with hemoglobin of the blood

• It forms a stable Carboxyhemoglobin  with the blood.

• This Carboxyhemoglobin is a very stable compound

• This reduces the oxygen carrying capacity of blood

• Therefore people die out of suffocation

B) Plastic bags are most common cause of suffocation for infants.

• Plastic bags when accidentally chewed by infants cause huge biological harm.

• They might enter the food canal or the esophagus
• This might lead to stomach infections
• If it enters the wind pipe it causes much more harm like the suffocation

C) Big objects generally choke children

• Big objects cannot be swallowed by food pipe neither they can pass through wind pipe
• Therefore unlike small objects they don't get digested by remain in these pipes causing suffocation

D) Children should be supervised while they are playing reasons being  

• They might accidentally swallow any plastic objects leading to suffocation.
• They might swallow small objects which might choke them.
