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.

Many scientists agree that the universe is about 13 billion years old.
All carbohydrates are made up of monosaccharides.
Explanation:
The carbohydrates are one of the crucial naturally occurring chemicals when it comes to the survival and prosperity of the living organisms. They serve lot of different roles, from providing energy, storing energy, fertilization, make up the RNA, strengthening the immune system etc.
The carbohydrates though are not all the same, and they can actually be divided into four different groups:
- monosaccharides
- disaccharides
- oligosaccharides
- polysaccharides
Each of them has different chemical composition, thus having different properties. Those different properties in turn result in different types of usages for each of them among the living organisms. The smallest units, the monosaccharides and disaccharides are actually the ones that are referred to as sugars, something that we all know very well and use it on daily basis.
