Answer:
Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.
Explanation:
Why does it matter?
As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.

Meiosis is the creation of sex cells so it isn't A or B. Meiosis makes two different gametes that are not identical so it has to be C
Answer:
Hypothesis
Hypothesis 1:Caffeine is a stimulant and will result in an increase in the typing speed of the participants.
Hypothesis 2:Caffeine is a stimulant and will result in a decrease in typing accuracy.
Hypothesis 3:The heart rate of the people will increase with the intake of caffeine.
Aim of the study
The aim of this study is to determine the following:
• The effect of caffeine on typing speed
• The effect of caffeine on typing and accuracy.
• The effect of caffeine on the heart rate of people.
