Answer:
c. The lungs are able to rid the body of a wide variety of acidic and basic substances, thereby directly adjusting the pH of the blood
Explanation:
Lungs help maintain the blood pH by regulating the partial pressure of CO2 and thereby, the amount of hydrogen and bicarbonate ions in the blood. As CO2 enters the blood, it is converted to carbonic acid (H2CO3) which in turn dissociates into hydrogen ions and bicarbonate ions. As the H+ concentration increases, the blood pH decreases. The increased breathing rate and increased gaseous exchange in the lungs compensate for the change in the blood pH. Removal of CO2 from blood reduces the H+ concentration in the blood and thereby, the blood pH is increased towards the normal range.
Answer:
The answer is B
Explanation:
The answer is B because Killer Whales eat pretty much everything on this chart. If something were to wipe out the Killer Whales, that means that all the other species in the web would increase in numbers because there is nothing there to moderate those numbers.
The Darwin's theory of evolution states that the organisms evolve through the process of the natural selection of the favorable genetic variations gradually over time. Through this process of the evolution, new species are developed over time. A single population may give rise to different species. These newly evolved species share similarities will each other as they have the same ancestor.
Hence, the given statement is 'true'.
A) proteins. They are called bilayers that consist of lipids that surround the cell and it's organelles.
