Answer:
<em>The correct option is B) 5-10%</em>
Explanation:
We have seen and depicted various scenarios where we see how different changes arise and dominate the world. Social scientists suggest that as low as 5-10% people of a population are enough to bring about a change because people tend to copy what others are doing. Same goes for countries of the world. Each new popular technique which is learnt by one country tends to become popular and learnt by other countries. For example, the usage of a social app starts with a few members of a population using it and with time it becomes popular in the whole world.
Answer: Carbon Monoxide is a very harmful and toxic gas which is formed from incomplete combustion of carbon.
Explanation: red blood cells contain haemoglobin ,which are responsible for carrying oxygen into our body system. So oxygen combines with haemagoblin to form oxyhaemogoblin in the red blood cells .
so if a person starts to intake cigarettes which contain high amounts of carbon monoxide ,it reduces oxyhaemogoblin formation because it binds very tightly to the haemogoblin .then carboxyhaemogoblin is formed and its permanent so causing reduction in aerobic respiration, and reduction in oxygen transport and causing damages to heart muscles.

Answer:
True
Explanation:
The sympathetic autonomic nervous system activates the body for hormonal or neuronal responses also known as fight- or - flight response, For example during an fire emergency and there is a need to run. The response occurs primarily by via impulses transmitted through the sympathetic nervous system, and also secondarily through catecholamines secreted from the adrenal medulla.
Although the sympathetic autonomic nervous system is activated in stressful conditions, it needs to be constantly active even at a basal level to maintain homeostasis.
