Biology Short Answer

Deforestation plays a big role in global warming. The “land use connection” referred to as “land use changes” is a huge contributor to global greenhouse gas emissions. Land use change involves all the destructions of land in order to produce and distribute food. Every year rainforests are demolished for agriculture intentions. “The biggest factors are the destruction of vital rainforests through burning and clearing and the elimination of wetlands” (Lappe 753). Deforestation of these habitats leads to the discharge carbon dioxide into the environment.

Deforestation is a process of cutting down too many trees and it largely affects the climate. The Amazon rain forest is a perfect example of this. In the past 40 years a full 20% has been removed from that single rainforest alone.When cutting down trees the process of photosynthesis can not take place. Therefore large amounts of carbon dioxide are left in the air, and there is less oxygen. These C02 bonds interfere with the C03 in the ozone. Global warming is greatly affected by deforestation due to the increase in greenhouse gases it causes. Tens of Millions of acres are being cut down each week. These acres are as large as Italy. When these trees have been burned carbon dioxide enters the atmosphere. Trees are 50% carbon dioxide, so when deforestation takes place lots of carbon dioxide is released. It accounts for 25% of carbon dioxide emissions.

Deforestation is the process of cutting or burning too many trees. In deforestation, forests are completely cleared, and that land is used for other purposes. Major example of deforestation is in the Amazon rainforest in South America. Within last twenty-six years, it went form a thick layer of green forest, to empty clean area. Cutting these breathe in CO2 and breathe out oxygen. Trees are a natural way to controlling CO2 in the atmosphere. Once the forest is clean in deforestation, these no natural way left for balancing CO2 in the environment that leads to too much CO2 in the air. Also, trees are made 50 percent with CO2 in them which they use for energy. When deforestation takes place, the CO2 from tree is released in the air. As said before too much CO2 increases temperature of the planet leading to global

Biology 102 introduces students to the concept of evolution, the principles of evolution, natural selection, and major kingdoms of living things organisms. My major is nursing and taking this course is a prerequisite and is required for my major. Taking Biology courses will help me be better knowledgeable in my chosen field. I took biology 101 last semester and we learned about cell and organisms. These are fundamentals things that someone who plans to have a career in the healthcare field needs to know. Also these courses are prerequisites for other science courses I have to take such as microbiology, human anatomy and physiology. As a future nurse these are information that will come in handy everyday. I have three years left in my undergraduate study and more

When trees are burned, CO2 is relinquished. The burning of astronomically immense areas of trees is known as deforestation. Human activities integrate more CO2 into the atmosphere through activities like the burning of fossil fuels. The guiding question of this investigation is, “Which carbon cycle process affects atmospheric carbon the most?” The researchers initially wanted to learn 2 things. First, the researchers wanted to learn how much carbon engenderment there would be if they incremented the amount of fossil fuels burnt by a certain amount. The researchers also wanted to learn how much carbon engenderment there would be if they incremented the amount of deforestation.

7)a) You would do the Benedict’s reagent test for simple sugars and the Lugol’s solution or Iodine test for polysaccharides and starch. To test the lipids you would use the Sudan iV test and Biurets reagent test for protein.

My sisters and I love to go shopping, we then have lunch together when we’re done

Forests play a critical role in mitigating climate change because they act as a carbon sink soaking up carbon dioxide that would otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns. Deforestation undermines this important carbon sink function. It is estimated that 15% of all greenhouse gas emissions are the

This is immunity in an organism that’s a result from the production of antibodies or lymphocytes after an antigen is identified in the body.

Deforestation is the clearing of a forest and/or cutting down of trees for human benefits such as agriculture, wood exports, etc. Deforestation is the cause of numerous environmental impacts such as habitat loss, flooding and soil erosion. It can also cause climate change, by reducing the amount of rainfall and changing the amount of sunlight reflected from Earth’s surface and increases the risk of forest . Tree growth is important for biodiversity because they absorb carbon dioxide which is a harmful greenhouse gas . However, since deforestation reduces natural carbon sinks, it disrupts the balance between oxygen and carbon dioxide in the air causing the amount of carbon dioxide in the air to increase. This poses a serious

Three to six billion trees are cut down each and every year! Deforestation is a huge problem in the rainforests. Because these forests are home to much of the Earth’s species of life. Covering 30 percent of our land forests provide homes, protection, and oxygen for humans and other wildlife in the forests. There are 7.125 billion people that count on the benefits provided by the forest, which is: food, clothing, traditional medicine and shelter. If something isn 't done soon to reduce our carbon footprint, we will not have forests of any type to soak up the carbon dioxide(CO2) in the atmosphere.

Recently, Global Warming has been a huge topic of discussion for many people. Deforestation has specifically contributed to harmful gases, including CO2 (Carbon Dioxide), being emitted into the atmosphere. According to Cesareo and Walker, “deforestation is the largest source of carbon dioxide emissions after fossil fuel burning, causing 15% of global greenhouse gas emissions”. Trees naturally absorb Carbon Dioxide, and when trees are removed from the environment,

In addition, human activities like deforestation may increase the amount of carbon dioxide in the atmosphere. This is because forests help in carbon sequestration, which reduces the amount of carbon dioxide in the air. It follows then that clearing such tress will increase the amount of carbon dioxide since carbon sequestration will not occur (3). The man-made theory of climate change also explains that when these harmful gasses reach the atmosphere, they form a blanket, which traps heat in the atmosphere. This trapping of in the atmosphere is the phenomenon that causes the planet to get warmer, hence the term global warming (Sharma, 4).

Deforestation, the cutting and burning of a forest, also increases the amount of carbon dioxide into the atmosphere. A NASA page says that “when a forest is cut and burned to establish cropland and pastures, the carbon that was stored in the tree trunks (wood is about 50% carbon) joins with oxygen and is released into the atmosphere as CO2. CO2, is, of
