All Living Species: Discussion Questions

1) DNA programs protein production in the cytoplasm by transferring its coded information to a molecule called RNA (mRNA). The RNA then carries the order to build this type of protein from the nucleus to the cytoplasm.

The rapidly increasing amount of carbon dioxide may be one of the factors that cause climate change. As Hillman states, “Concentrations of carbon dioxide in the atmosphere are increasing, and have done so since the Industrial Revolution.” An atmospheric CO2 concentration, research shows that there is a dramatic increase from 280 parts per million (ppm) in 1750 to 373 ppm in 2002, a rise of the third. Furthermore, the linear chart demonstrated the trend of annual global CO2

(d.) Biologists agree that there is sufficient evidence to concede to the sexual selection hypothesis and that the food competition hypothesis needs further testing.

In eukaryotes, stored primarily in the cell nucleus. A nucleic acid using deoxyribose rather than ribose.

B) Seasonal fluctuation of temperature is not a limiting factor in biome distribution if areas have the same annual temperature and precipitation means.

This means that what you eat actually contributes to the amount of green house gases that are released into the atmosphere.

Secondly, together with deforestation of the planet, the burning of fossil fuels is contributing to a measurable increase in the concentration of carbon dioxide in

1 . Species living today are descended from other species that live in the past .

As carbon dioxide is a greenhouse gas, increased concentrations of it have led to an amplified greenhouse effect. More solar infrared radiation is re-emitted and absorbed by the Earth, causing surface temperatures to rise. Therefore, the density of the surface waters will decrease, which means there is a greater

“CO2 gas emissions” is a mystical term which everyone should pay attention to. C02 gas is a colorless, odorless gas that is present in the atmosphere and is formed when any fuel containing carbon is burned. Plants and trees are using it in the process of photosynthesis. Carbon dioxide is also used in refrigeration, fire extinguishers, and carbonated drinks. In other words this is the gas we need to fight with! By using fossil fuels in almost everything we do, we make a huge cloud of gas and this is warming up the world. By doing this, we cause serious damage to the nature and we may have an irreversible effect on it and the future.

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).

It is reported that nearly three quarters of green house gases are a result of humans burning fossil fuels from nonrenewable energy, cars, and electricity (LaMeaux, 2014). The effects of carbon emission on climate change are having devastating and many irreversible
