The process that occurs in a cell when there is not enough oxygen
is called fermentation. Fermentation occurs through the process of Anaerobic Respiration,
where instead of using oxygen, organic and inorganic molecules are used as
final electron acceptors. The by-product of this process is usually alcohol,
ethanol, or acetic acids.

Fermentation is commonly used in lactic acid (in muscles) and alcohol (beers,
whiskey) fermentation where the by-product is ethanol. Yeasts are a common
organism that uses this process, where it convert sugars into alcohols or
acetic acids.</span>
Answer:
Contraceptive Education/Availability, Healthcare, Country Development, and Political Climate
Explanation:
When people are educated about proper contraceptive use they can still have sex without the consequence of pregnancy. The availability of contraceptives goes hand in hand with contraceptive education.
Advanced healthcare can help prevent disease through immunizations and further the life expectancy of the country's population. Hand washing can significantly lower the spread of disease.
The lower the development of a country the higher the birth rate is, while the higher the developed countries have a lower birth rate and their life expectancy is much longer.
The political climate of a country can greatly affect the population growth. The more negative the political climate is usually causes a smaller birth rate. For example when China implemented the one child policy their population growth declined;.
This statement means that evolution has happened by getting the genes of the right trait expressed at the right time to help adaptability.
Explanation:
Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.
We can conclude that all features are not adaptable some are the results of genetic drift or mutations.
In case of cheetah, the faster running genes would have been there they got expressed over the period of time for better adaptability.
Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition
