Explanation:
The current world population of 7.6 billion is expected to reach 8.6 billion in 2030, 9.8 billion in 2050 and 11.2 billion in 2100, according to a new United Nations report being launched today. With roughly 83 million people being added to the world’s population every year, the upward trend in population size is expected to continue, even assuming that fertility levels will continue to decline.
The World Population Prospects: The 2017 Revision, published by the UN Department of Economic and Social Affairs, provides a comprehensive review of global demographic trends and prospects for the future. The information is essential to guide policies aimed at achieving the new Sustainable Development Goals.
Answer:
The change in color in the flowers is because the plant has absorbed the dyed water. After some hours, we can see that the water has ascended through the roots, the stem and reached the flower petals. We can see the water's path till it evaporates in a process called transpiration, which returns water to the atmosphere.
Explanation:
Plants absorb water and other nutrients so that they can live. When we add ink into the water, we can see the water's path from the roots, up the stem, the leaves, and the flowers. In the flowers, the water evaporates through the stomata. We call this process transpiration. The ink allows us to see that the water was in the petals, but it evaporates, leaving behind the ink. As water evaporates, the plant drinks more, which results in a more intense color in the petals.
