Increase in carbon dioxide in your red blood cells, which causes a drop in pH, causes your breathing to speed up.
The presence of carbon dioxide in red blood cell will lower the pH because carbon dioxide combines with water to form [tex]H^{+}[/tex] and [tex]HCO_{3} ^{-}[/tex] .
About 70% of Carbon dioxide transported as bicarbonate ion in the plasma of the red blood cells .When carbon dioxide diffuses across the cell membrane of erythrocyte then it reacts with water to form carbonic acid.This carbonic acid breaks into bicarbonate ion and proton in the presence of carbonic anhydrase . this is because it is very unstable.This hydrogen ions binds to the hemoglobin and which results in initiation of bohr effect .So, as concentration of hydrogen ions increases pH of the blood decreases.learn about carbonic acid

The highest pressure ever produced in a laboratory setting was about 2.0 x 10 6 atm. If we have a
1.0 x 10 -5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm,
what would the new volume of that gas be?
Answer:
Volume = 72.7272
Explanation:
if only pressure and volume change, then we can do some simple math to find the answer.
2 x 10 ^ 6 times 1 x 10 ^-5 = 20
pressure and volume must equal 20
20 = 0.275 x volume
20 / 0.275 = new volume
I don't remember significant digits but your volume is 72.72727272 just repeated
If we have a 1.0 x 10 -5 liter sample of a gas at that pressure, then release the pressure until it is equal to 0.275 atm, the new volume will be 72.7272
What is Volume?Volume is the space occupied by a three-dimensional object.
By the Boyle's law
[tex]\rm P_1V_2= P_1V_2[/tex]
P1 (initial pressure) = [tex]2.0 \times10^6 atm[/tex]
V1 (initial volume) = [tex]1.0 \times10^-5 L[/tex]
P2 (final pressure) = 0.275 atm
V2 (final volume) = ? (in L)
Putting the values in the equation
[tex]\rm 2.0 \times10^6 atm \times 1.0 \times10^-5 L = 0.275 atm \times V_2\\\\V_2 = \dfrac{20}{0.275} = 72.72 L[/tex]
Thus, the volume is 72.72 L.

If we had 79.3 grams of Xe, would we expect a volume that is
greater than or less than that obtained with neon?
a
Greater than
b Equal
с
Less than
Answer:less than
Explanation:
If we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).
What is Density?Density is defined as the mass per unit volume of a substance. The most commonly used symbol for density is ρ, although the Latin letter d can also be used. Density is defined as mass divided by volume:
[tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]
where ρ is density,
m is mass, and
V is volume.
The mass contained per unit volume of an object is known as density. where the SI unit of density is kilogram per cubic meter [tex](kg/m^3).[/tex] Density is inversely proportional to volume, so the density of Xenon is [tex]5.894 kg/m^3[/tex] while the density of neon is 0.89994 kg/m³. So, if density is more than volume will be less and vice versa. In this case, density of Xenon is more as compare to neon so, the volume of neon will be more.
Thus, if we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).

Which of the following statements is FALSE?
The microscopic size of cells enable them to function properly.
Most organisms on Earth are multi-celled.
Some cells can be shaped like a ball.
Growing children’s cells are constantly dividing.
Answer:
The answer is functioning properly ok dude?
Explanation:
Answer: "The microscopic size of cells enable them to function properly.
Most organisms on Earth are multi-celled." is false
Explanation:
In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Survival of the eukaryotes depends upon interactions between many cell types, and it is essential that a balanced distribution of types be maintained. This is achieved by the highly regulated process of cell proliferation. The growth and division of different cell populations are regulated in different ways, but the basic mechanisms are similar throughout multicellular organisms.

The planets in the solar system revolve around the Sun because the Sun is
Answer: Anyway, the basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. ... If the Sun weren't there, the Earth would travel in a straight line. But the gravity of the Sun alters its course, causing it to travel around the Sun, in a shape very near to a circle

Answer: i gotcu the answer is mass
Explanation: The more weight of the object the more its subject to gravity like a feather barley is while a bowling ball smashes into the ground :D
The property allows objects to be subject to gravity is mass. Therefore, option B is correct.
What is mass ?Mass is a physical body's total amount of matter. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term.
The strength of an object's gravitational attraction to other bodies is also influenced by its mass. The kilogram serves as the SI's fundamental mass unit. The amount of matter object present is also known as mass.
The amount of matter that makes up every item or body is the greatest way to understand mass. Everything that we can see has mass. Examples of objects with mass include a table, a chair, your bed, a football, a glass, and even air. The mass of a thing determines whether it is light or heavy.
Thus, option B is correct.

differences between alkalis, bases and acids? (answer for many points :) )
Explanation:
protons.
An acid can also be thought of as a chemical that can neutralize a base. Similarly, a base can neutralize an acid.
Acids turn litmus paper red, while bases make litmus paper turn blue.
Some examples of acids are sulfuric acid, hydrochloric acid, nitric acid, and so on. Some examples of bases are sodium hydroxide, potassium hydroxide, and so on.
Acids generally taste sour, while bases have a bitter taste.
Alkalis are the bases that are water-soluble, which means that they dissolve in water. In other words, not all bases are water-soluble, and only the water-soluble bases are known as alkalis. An example of an alkali is sodium hydroxide. It is a base because it can neutralize an acid, and because it is water-soluble, it is an alkali. An example of a base that is not alkali is copper oxide. This chemical can neutralize an acid, but it is insoluble in water.
In other words, all alkali are bases but not all bases are alkalis.
Also, an alkali has a hydroxide group, while a base has an oxide group in it.
