ANSEWER: In 2017, 71% of the global population (5.3 billion people) used a safely managed drinking-water service – that is, one located on premises, available when needed, and free from contamination.
90% of the global population (6.8 billion people) used at least a basic service. A basic service is an improved drinking-water source within a round trip of 30 minutes to collect water.
785 million people lack even a basic drinking-water service, including 144 million people who are dependent on surface water.
Globally, at least 2 billion people use a drinking water source contaminated with faeces.
Contaminated water can transmit diseases such diarrhoea, cholera, dysentery, typhoid, and polio. Contaminated drinking water is estimated to cause 485 000 diarrhoeal deaths each year.
By 2025, half of the world’s population will be living in water-stressed areas.
In least developed countries, 22% of health care facilities have no water service, 21% no sanitation service, and 22% no waste management service.
The correct answer is letter B. The food molecules that cannot be digested need to be eliminated from the body. This can be done by taking in certain kinds of medicines that stimulate the digestive tract to pass out the food molecules that are indigestible.
Cancer is the noncommunicable disease
Answer:
1.3
Explanation:
Relative density can be obtained from;
Upthrust in liquid/upthrust in water
Upthrust in liquid = Weight in air - Weight in liquid
upthrust in water = Weight in air - Weight in water
Hence;
Relative density = Weight in air - Weight in liquid/Weight in air - Weight in water
Relative density = 3.4 N - 1.5 N/ 3.4 N - 1.9 N
Relative density = 1.9 N/ 1.5 N
Relative density = 1.3
