The graph shows the growth and reproduction in 4 different cells, A, B, C, and D, over time. Use the graph to answer questions b
balandron [24]

Answer: A.

Explanation:

Cells generally have a relatively short lifestyle in that they grow, divide and then die off. This is not the case with cancerous cells as those ones mutate and then multiply such that they eventually form a tumor.

Looking at the graph, most of the cells are remaining at a lower or manageable number because they are dying off. Cell A on the other hand is simply increasing in number which means that it is a cancerous cell as it is increasing its number by mutating instead of dying off like other cells would.

Most extinction is ________.
Maksim231197 [3]

An extinction event is a well-known and quick decrease in the biodiversity on Earth. Such an occurrence is recognized by a sharp change in the diversity and abundance of multicellular organisms. It happens when the rate of extinction surges with respect to the rate of speciation. In other words, this happens when species cannot adapt generally to the change in the environment. So the correct answer would be letter a.

How is the oxygen cycle disturbed by deforestation
eimsori [14]

Answer:

If deforestation is disturbed then the photosynthesis cycle is disturbed, which results in the oxygen cycle being affected. With a decrease in trees, a decrease in photosynthesis occurs, which cause a decline in the oxygen cycle. A decline in the oxygen cycle results in more polluted air.

Explanation:

Without trees, humans would not be able survive because the air would be unsuitable for breathing. Due to deforestation, there would be fewer trees to "clean" the air. Deforestation is the action or process of clearing of forests, or the state of having been cleared of forests.

Trees and plants, in general, produce energy for growth using a process known as photosynthesis. Using light, water and carbon dioxide, a plant produces energy in the form of sugar and releases oxygen into the air.

Deforestation, as well as a rise in the emissions and our global temperature, affects the air that we breathe. This is because all trees take in carbon dioxide and other pollutants which are known to cause a lot of problems in the atmosphere and to humans. This inevitably results in people breathing dirtier and more polluted air that normally wouldn't happen.  

Long-term exposure to polluted air can have permanent health effects such as: Accelerated aging of the lungs. Loss of lung capacity and decreased lung function. Development of diseases such as asthma, bronchitis, emphysema, and possibly cancer.

Trees are responsible for taking the carbon from the atmosphere through photosynthesis in order to make energy. This carbon is then either transferred into oxygen and released into the air by respiration or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly higher amounts of carbon dioxide in the air and lower amounts of oxygen. This bad quality air would also be full of airborne particles and pollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide.

In addition to the decrease of oxygen in the atmosphere, it would allow excessive amounts of carbon dioxide to remain. In the short term, since CO2 is one of the major greenhouse gases, it will undoubtedly lead to higher global temperatures which, in turn, would quicken the melting of the polar ice caps.
