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.
Hey there,
The correct answer would be: An eagle

So in this scenario, we have to consider two things: the plants are super different from each other. Some plants have huge leaves, others have tiny ones-- some plants have really long roots, others barely have them; it is because of these differences that the some plants survive better than others.
Say that at the start, plants are thriving like crazy-- I mean they're everywhere man.
But afterwards, this huge environmental change occurs.
Plants that have bigger leaves lose more water due to a greater rate of transpiration. Plants with shorter roots can't reach the water deep in the soil.
Plants with smaller leaves, and waxier cuticles could protect their water more. Plants with longer roots could get more water.
Basically, all plants that have good traits for drier environments tend to survive more.
Because they tend to survive more-- they could make more baby plants (i.e. greater rate of reproduction)
Because they could make more baby plants, the overall newer generation of plants will have more of these hardy, dry-environment adapted plant traits (i.e. phenotype).
The correct answer for this question is (D) It can proceed in the dark.
Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>
The Calvin cycle proceeds in three stages:
1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate
2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH
3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.
