Answer:

Origin of Species was a book that was published in 1859 by Charles Darwin on human evolution. This theory was based on natural selection.

Explanation:

The evolution theory was first proposed by Darwin in 1856 in his book Origin of Species. In this theory, Darwin explains the changes in species over time result in the changes in the traits and heritable qualities. Evolution occurred by natural selection. In this theory, scientists show two main points that, all species are connected on this earth and the diversity in the population is the result of the modification in traits by time.

For Example, one study on 1900 students on human evolution was published in the journal " Personality and Individual Differences". According to this research, people are hard to find their soul mate because the changes are very rapid in traits.

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enz
Gala2k [10]

Taq polymerase enzyme important for efficiency in PCR because it is thermostable polymerases that remain active at high temperatures (90 -95  degree Celsius) a beyond the denaturation temperature of DNA.

PCR :

Polymerase chain reaction (PCR) is a laboratory technique for rapidly amplifying millions to billions of copies of a specific segment of DNA, which can then be used for further research.

Taq polymerase is a DNA polymerase derived from bacteria called Thermus aquaticus, which are naturally thermophilic and is a thermostable polymerases that remain active at temperatures higher than the temperature at which DNA is denatured. This allows PCR to be used on DNA samples without the need to add new DNA polymerases after each cycle.

Briefly explain the four different types of acid-base disturbance found in the human body
slega [8]
Respiratory acidosis.
Respiratory alkalosis.
Metabolic acidosis.
Metabolic alkalosis


Respiratory acidosis = Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces. This causes body fluids, especially the blood, to become too acidic.


Respiratory alkalosis = Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35–7.45) with a concurrent reduction in arterial levels of carbon dioxide. This condition is one of the four basic categories of disruption of acid-base homeostasis.



Metabolic acidosis = Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance. Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids.


Metabolic alkalosis = Metabolic alkalosis is a condition that occurs when your blood becomes overly alkaline. Alkaline is the opposite of acidic. Our bodies function best when the acidic-alkaline balance of our blood is just slightly tilted toward the alkaline.

Cholesterol is an organic steroid in mammalian cells that controls membrane permeability and fluidity. How many hydrigens
Kisachek [45]

There are 46 atoms of hydrogen inside the cholesterol.

The formula of cholesterol is C27H46O, meaning that besides hydrogen it contains 27 atoms of carbon and one atom of oxygen.

Cholesterol can be found in large concentrations within the liver, spinal cord, and brain providing the stability of the cell membranes.
