Charles Darwin's Theory of Evolution by Natural Selection proposes:

<span>·         </span>In each generation, more people are produced and survive.

<span>·         </span>Phenotypic variation is heritable.

<span>·         </span>Those with heritable traits that matches with the environment will most likely survive.

<span>·         </span>New species rise after reproductive isolation.



Charles Darwin took inspiration from economics and chose observable data to form his theory. The speculations before his time drove him to study how the ideas fit together, piecing information and making conclusions. The intellectual environment was both supportive and competitive,motivating the theorist.



Jean Baptiste Lamarck was a French naturalist and proposed that species change from single-celled forms through time to complex ones.

Charles Lyell was an English geologist who discussed gradual geological processes have slowly and steadily shaped the surface of the Earth and that the planet must be older than most believed.

Thomas Malthus was an English economist who asserted that human population increases faster than resources. The imbalance will cause a decrease in the population because of famine and disease.

Katyanochek1 [597]
The answer is D, photosynthesis and respiration.


—Evidence—

Oxygen is a byproduct of photosynthesis and, correspondingly, carbon dioxide the byproduct of respiration.

A side note about haemochromatosis:

Haemochromatosis is a disease where there is too much iron is in the body.  It is the most common form of iron overload disease. There are two types of haemochromatosis: 

<span>Primary haemochromatosis is a genetic disorder inherited from family members.  People with this condition absorb too much iron and it ends up accumulating in the body, especially in the liver.   </span><span>Secondary haemochromatosis is caused by other blood-related disorders such as anaemia, or may be due to many blood transfusions, long term alcoholism and/or other health conditions.    </span><span>If left untreated, iron overload can lead to liver damage. That’s why it’s important to receive treatment as soon as possible after diagnosis to prevent further complications, including liver disease, liver cirrhosis, liver failure, liver cancer, heart disease, arthritis or diabetes. Some organ damage can be reversed if detected early enough and treated appropriately.

cigarettes

If you smoke cigarettes there’s a chance that you are causing damage to your liver – increasing your risk of developing liver cancer and decreasing your liver’s ability to rid your body of dangerous toxins. In turn, this could leave you more susceptible to the damaging effects of some medications on the liver too. </span>
