They needed food and supplies; Ulysses was curious.
Answer:
Oxygen in it's purest form is a deadly gas that would kill is almost instantly. It is the cause for most (if not all) cases of combustion. We breath in two molecules of oxygen, which stabilizes the compound and allows us to dispel carbon dioxide safely. It only comprises a small part of the atmosphere though. The air is made up of around 93% nitrogen, which is vital for the survival of certain species on earth. There is also a carbon cycle in the air which will be destroyed, given that only oxygen was in the atmosphere.
If your carbohydrate consumption was low, then the process of making ATP would quickly diminish. Carbohydrates are the main source of energy to cells, and it's because of them that we can make ATP.
This would affect your cells by slowing them down, which ultimately slows you down as a whole. If it gets too serious, death can occur.

Answer:
When the conclusions of research are based on the interpretations of the investigator, qualitative research has been employed. However, if the conclusions are based upon statistical analyses of the data, quantitative research has been employed.
Explanation:
Simply put, qualitative research does work with numerical data. Its purpose is to analyze more abstract concepts and situations, such as individual's or groups' opinions, behaviors, beliefs, interactions etc. On the other hand, quantitative research works with numerical data and relies on statistics, computation, and mathematics to come to results. Its purpose is to quantify the problem under study.
Desertification has become a major issue in Africa,
specifically in sub-Saharan Africa. The area most at risk is the Sahel, the area that borders the
southern edge of the Sahara. This region serves as a “transition” between the
desert and savanna the
grasslands that dominate much of sub-Saharan Africa. The centrally-located tropical rainforest region is
not immediately affected by the threat of desertification.
The term
“desertification” refers to the growing size of deserts, but in this case the Sahara. There are many causes of
desertification: some are naturally occurring while others are caused by
humans. The most common natural cause is drought,
which is something you might associate with the desert itself. However, this
situation can cause great harm to soil, making it unusable and causing<span> erosion</span> by wind or human
activity.
As far as human activity goes, there are number of them that cause
desertification. Cattle ranching- a common occupation in much of rural Africa-
can cause overgrazing.
Additionally, the need for more and more food to feed people in and outside of
Africa results in over-farming.
In both cases, these practices cause soil to become more exposed to the sun and the increasingly dry weather. As the
soil loses nutrients and is loosened by other forces, it ceases to be able to
grow any plant life, creating a situation in which the desert may slowly begin
to creep into an area.
The effects of desertification can be catastrophic. Starvation is the most common
effect, and one that is not quickly or easily solved. Soil that is unusable can
take many generations to replenish.
Similarly, ending or slowing down desertification is cannot be done with a
single effort. Military
campaigns are being undertaken in Africa, encouraging the use of beneficial
practices such as crop rotation
and smarter ranching
practices in order to prevent further soil depletion.
