b. CO2 (g)
c. CO2 (s)
d. CO2 (gp)
Answers
This notation is commonly used in showing chemical reactions wherein the phases of the constituents are important. Gases are denoted by (g), solids are denoted by (s), and liquids are denoted by (l). Aqueous solutions are also denoted (aq).

The type of epithelial cells that would be found in an area of the body where diffusion of nutrients needs to occur is squamous.
- Epithelial cells refer to the cells that are vital in the lining of the surface of the body. Epithelial cells can be found on the blood vessels, skin, and urinary tract.
- It should be noted that epithelial cells are important as they act as a protective barrier and help in stopping viruses from getting inside the human body.
- It should be noted that squamous can be found in an area of the body where diffusion of nutrients needs to occur. They're flat cells and they are usually thin and resembles the scale of fishes.
In conclusion, squamous can be found on the surface of the skin.

Starch is a carbohydrate which is a polysaccharide and not a simple sugar like glucose, fructose,etc.
What are carbohydrates?
A carbohydrate is defined as a bio-molecule which consists of carbon,hydrogen and oxygen atoms which are usually in the ratio of 2:1 with the empirical formula C(H₂O)
.
This term is most commonly used in biochemistry as a synonym of saccharide which is a group of sugars, starch and cellulose.
They perform various functions in living organisms. They serve as an energy source and as well as structural components . They are a key component in providing nutrition and are found in wide variety of natural as well as processed foods.
Carbohydrates occur as cellulose in the cell walls of plants and is one of the components of insoluble dietary fibers.

volume
For the sake of explanation, let's pretend the mass is 2g and the volume is 1 ml
Density = 2 g = 2 g/ml
1 ml
Now if we increase the volume, and leave the mass the same then mass is still 2g, but we can increase the volume to 2 ml
Density = 2 g = 1 g/ml
2 ml
Therefore we can say that if volume increases and mass stays the same, then density will decrease.
ρ = m/v
Let's plug in some numbers to see how this looks, we'll say the object weighs 1 kg and it's volume is 2 cm^3
Thus, ρ = 1 kg / 2 cm^3
So, density in this case is equal to 1/2 kg for every cm^3.
Now let's increase the volume and keep the mass. We'll double the volume.
ρ = 1 kg / 4 cm^3
Now the density comes out to 1/4 kg for every cm^3, which is obviously less.
We've come to the conclusion, then, that as volume increases and mass stays the same, density decreases. Therefore volume and density are inversely proportioned.
This makes sense mathematically, but does it make sense if we just think about it? It invariably does.
What is density? Density is just how much mass is stuck in a certain space. As such, when you increase that space, but keep the mass, the mass will be more sparsely distributed.
Think of it like this, you've a small room filled to the brim with toys, should you increase the room size, but keep the same amount of toys, then the toys would be further spread apart.
It is the same way with mass and volume.
Hope this helps :)
