Answer:

It is true that studying natural selection in the fields can be challenging. Some of the challenges which Darwin might have faced could have been:

Darwin was only studying one trait for his results. But there might have been many other factors or traits affecting natural selection.

Natural selection does not happen rapidly hence Darwin would have had to wait for many generations to observe the results.

The environment is not such an easy factor to study. It is complex. It might have happened that the environment might have changed before any changes were seen in the population of the birds.

hram777 [196]

Answer:

Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.

Explanation:

When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.

On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.

Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.
