Based on current data;
- The amount of carbon dioxide put into the atmosphere annually dueto human activities is 840 gigatons
- The amount of carbon in the atmosphere is 10 gigatons
- The amount of carbon stored in fossil fuels is 10,000 gigatons
<h3>What is the carbon cycle?</h3>
The carbon cycle a cycle showing how carbon is recycled between the atmosphere and earth.
The carbon cycle ensures that their is a balance of carbon in the atmosphere as well as on earth.
Human activities have increased the amount of carbon in the atmosphere.
The amount of carbon dioxide human activities put into the atmosphere annually in the present day is 840 gigatons.
The amount of carbon in the atmosphere is 10 gigatons
The amount of carbon stored in fossil fuels is 10,000 gigatons
Therefore, it can be concluded that human activities disrupt the carbon cycle.

Answer:
2. meiosis I only
Explanation:
During the zygotene stage of prophase-I of meiosis-I, homologous chromosomes synapse and are paired up. These paired homologous chromosomes are called bivalents. These paired homologous chromosomes align themselves at the equatorial plate of the cell during metaphase-I. Therefore, when observed through a microscope, cells are shown lined up two by two. During meiosis-II and mitosis, individual chromosomes with two sister chromatids are aligned at the cell's equator in metaphase.
Answer - Genetic Engineering (Confidently Correct)
Reason - With Technology we can change the genetics of a species and help it adapt to it env. to survive longer and reproduce.
Streams that flow beneath melting glaciers leave long ridges of layered sediments, known as Esker. Eskers are formed within ice-walled tunnels by streams which flowed within and under glaciers. They tended to form around the time of the glacial maximum when the glacier was slow and sluggish and after the retaining ice walls melted away, stream deposits remained as long winding ridges.
