Answer:
Increase
Explanation:
As CO2 enters the blood, most of it is converted to the carbonic acid in a reaction catalyzed by carbonic anhydrase. The carbonic acid dissociates into hydrogen ions and bicarbonate ions. As the H+ concentration increases, the blood pH decreases. Thus, the increased partial pressure of CO2 produces a more acidic environment. Increasing the volume of air that reaches the alveoli and takes part in gaseous exchange will increase the rate of removal of CO2 from the blood. The reduced CO2 levels in the blood would increase the blood pH.
Function of
centrioles
An organelle that forms a
spindle-shaped structure of protein fibers on which the chromosomes move during
nuclear division are called the centrioles. Centrioles are part of the animal
cell organelles. Hence, they are a small part of the microtubules organized and
set in a particular course. Microtubules include 9 sets. Centrioles contain a
cylindrical structure, packed with protein which is described as tubulin. Found
mostly in eukaryotic cells beside the nucleus.
Bees are endangered because of environmental stress. Environmental stress may come from pollution, exposure to lethal amounts of pesticides, and due to scarcity of pollen.
The overall concept a clad organ aims to prove is evolutionary relationships among each organism.
