Answer:
Explanation:
For many, water scarcity is a problem in the post. By 2025, one in every two people on the planet will live with water stress. For one in nine, the problem is already here. ... In response, the United Nations made water and sanitation a matter of human rights, declared and defined, in 2010.
Access to water and sanitation are recognized by the United Nations as human rights, reflecting the fundamental nature of these basics in every person’s life. Lack of access to safe, sufficient and affordable water, sanitation and hygiene facilities has a devastating effect on the health, dignity and prosperity of billions of people, and has significant consequences for the realization of other human rights.
People are rights-holders and States are duty-bearers of providing water and sanitation services. Rights-holders can claim their rights and duty-bearers must guarantee the rights to water and sanitation equally and without discrimination.

Explain t<em>he ability of the retina to maintain an image a third of a second after viewing it, even when the image passed quickly.</em> This allows the brain to analyze and process the image. Due to this process, the visual information is processed continuously, much like a movie, instead of having pauses between images.
<em>I hope this information can help you.</em>
Answer: you would see an afterimage of a flag with the opposing colour systems(blue,black and red in middle), then white surface of the paper
Explanation: The opponent-process theory states that the cone photoreceptors are linked together to form three opposing colour pairs: blue/yellow, red/green, and black/white and the activation of one member of the pair inhibits activity in the other.
So after staring at a white sheet of paper for a minute, the yellow, white and green parts of the three opponent-process systems would be fatigued and unable to oppose the blue, black and red parts of these systems when you stare at the white sheet of paper. Therefore after seeing white, you would see an afterimage of a flag with alternating blue and black stripes and a block of red in the middle. Once the opposing parts of the three systems recovered, the flag afterimage would disappear and you would then see the white surface of the paper.
