it would be (D) because you cant see an atom without a microscope and a model is a larger model of the actual thing.
<span>Calcium<span> is the element responsible for most of the material found in teeth.
Calcium plays a vital role in the formation and maintenance of healthy teeth and gums. Calcium makes the jawbones healthy and strong in order to hold the teeth in place.
Dairy foods such as cheese and yogurt, beans, cabbage and brown rice are good sources of calcium.</span></span>
The part of the amino acid that gives the molecule its unique or characteristic chemical properties would be the R-group. Every amino acid has three main groups in it namely the amino group, carboxyl group and the R group. "R" represents different organic chain that is specific to a certain amino acid which gives different properties of the molecule.

Answer:
If I add sugar or salt, the water's density will increase.
Explanation:
Density is the relation between mass and volume. We can represent it with the formula δ= m/v. Where δ stans for density, m for mass, v for volume.
If we add salt or sugar, we increase the mass, but the volume is the same. As a result, the density will increase.
We can use numbers to understand it better.
Suppose that before adding salt or sugar, the mass is 1 g and the volume is 1 l
δ= 1g/l1t
δ= 1 g/lt
Now, if we add sugar or salt, the mass increases. Suppose that we have 2g of mass and the volume is the same, 1l.
δ= 2g/1lt
δ= 2g/lt
We can see that the density increased when the mass increased.
