The pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.
What is deforestation in the Amazon rainforest?Deforestation in the Amazon rainforest has significant environmental consequences. Trees store large amounts of carbon dioxide, and their removal contributes to increased greenhouse gas emissions, which are a major cause of climate change. Additionally, the cattle that are raised on cleared land produce methane, which is another potent greenhouse gas. As more trees are cleared to make way for agriculture and cattle farming, the carbon storage capacity of the forest is reduced, and more methane is released into the atmosphere.
Hence, the pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.

a scientist is observing a eukaryotic cell and a prokaryotic cell. which structure could she only observe in the eukaryotic cell?
A.) cytoplasm
B.) DNA
C.) ribsomes
D.) Nucleus
Answers
Answer:
The answer is D. Nucleus are only found in Eukaryotes.
Explanation: In the question, we are told to find a structure that is found ONLY in eukaryotic cells. Because of this, we have to eliminate any option that is found only in prokaryotic cells, or any that is found in both prokaryotic and eukaryotic cells. In options A-C, we are given structures found in both types of cells. The cytoplasm, DNA, and ribosomes differ in each type of cell; however, nevertheless, they do not only appear in eukaryotic cells. This makes nucleus the only valid option, as it is only found in eukaryotic cells.

The role played by the systems of the body in ensuring survival of farm animals in hot and dry climates
Answers
Answer:
Answer to the following question is as follows;
Explanation:
Domesticated animals have a natural instinct to seek out cover and seek refuge from the scorching heat. Their bodies, on the other hand, have inherent defensive systems to help them cope with heat and dryness. One of these is their covering or fur, which gives sun protection.
Animals living in hot, dry climates consume a lot of water, which is subsequently stored in their tissues to keep them from becoming dehydrated. Sweating is accomplished by certain animals by keeping their mouths open.
What is the elevation of point B
Answers
Answer: c. Point B has an elevation less than 2750 feet.
Explanation:
The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.
Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.
