No Clean Water: We may live on a water planet, but 97.5% of that water is ocean and other undrinkable salt-filled sources. Only 2.5% of the water on this planet is fresh, and of that, 1% is either too polluted to be consumed or entirely unreachable. Much of it remains frozen in the form of polar ice caps. All told, less than 1% of the planet’s freshwater resources are available for consumption.
Lower Life Expectancy: Thanks to medical intervention, human beings can live to be up to 100 years old — as long as they live in developed countries where they have access to that medical care. One study, done by researchers at Harvard, found that the majority of population increases over the next 40 years or so will be in less developed countries.
Climate Change: We’ve been seeing the results of climate change firsthand in the dramatic weather patterns of 2017 — multiple category five hurricanes, dramatic wildfires and floods, and other atypical weather patterns that are threatening both lives and property.
The correct option for given statement is
D
I and II only
I. Enzymes are not consumed during a chemical reaction.
II. Enzymes are specific to particular molecules
Explanation:
Enzymes are biological molecules (typically proteins) that considerably speed up the speed of nearly all of the chemical reactions that turn up at intervals cells.They're necessary|important} always and serve a large vary of important functions within the body, like aiding in digestion and metabolism.
Answer:
Option: A and D are the correct answer.
A. 50% and D. 25%
Explanation:
We know that the probability of an event is the chance of occurring of an event.
The probability of an event always lie between 0 and 1.
It is equal to zero if the event will never occur and is equal to 1 if the event is certain to occur.
Also, the probability could be in ratio or it could be in percentage and the percent may be between 0%-100%
Hence, in the given options:
B) 557 is incorrect as the probability is greater than 1.
c) 1×104=104 is incorrect since the probability is greater than 1
Hence, the correct options are:
A. 50%
and D. 25%

Scientists claim that Bisphenol A when ingested may cause brain problems, behaviour and reproductive development problems in foetus, children and even infants.
Option D.
Explanation:
Bisphenol A was a very common compound to produce polycarbonate bottles. This bottles were very commonly used to produce baby bottles, different beverage containers, different water bottles etc. Until 2010, BPA was allowed as a safe to consume ingredient by WHO but after 2010,they strictly restricted the levels of BPA in food because it has severe ill effects in human body.
Even low amounts of BPA in food can cause hypertension, coronary heart disease, atherosclerosis etc. Although not proven, but BPA is thought to cause cancer. Effects on children and infants are more prominent which can cause problems in development of reproductive structures and brain. Even in adults, the brain problems may lead to change in their behaviors.
