Answer:
c Example 1 represents a liquid and Example 2 represents a solid.
Explanation:
Example 1: Young children dancing slowly around one another
The young children dancing slowly around one another can be pictured as the flow of liquid. In liquids, the molecules are held about weakly and they slide on top of each other. They are held by weak attractive forces. This is clear picture of a liquid.
Example 2: Newborn babies sitting in their given spots in a crib
This is clear example of a solid. In a solid the molecules are held about a fixed spot. The attractive forces in liquids is very great and the molecules therein do not move about randomly.
The answer is asparagine interactions between aspartate and arginine side chains at neutral pH
<h3>
What side chain does arginine have?</h3>
- The amino acid arginine has the formula (H2N)(HN)CN(H)(CH2)3CH(NH2)CO2H.
- A guanidino group is attached to a typical amino acid framework in the molecule.
- The carboxylic acid is deprotonated (CO2) and both the amino and guanidino groups are protonated, resulting in a cation at physiological pH.
- The guanidine group in arginine is the precursor for nitric oxide production. it is a white, water-soluble solid, like all amino acids.

Answer:
22.5 mL
Explanation:
We are given an amount of a fluid in a graduated cylinder and required to determine its volume.
Liquids always take the shape of the container they are placed in. In the graduated cylinder shown, note how the top of the fluid curves downwards. The volume of the liquid is usually determined at the bottom of this curve or what is called the meniscus.
The bottom of the meniscus is at the 22.5 mL level and thus the volume of the fluid is 22.5 mL
Answer:
Al: 3
S: 6
Explanation:
Al is in Group III. This means that it has 3 valence electrons.
S is in Group VI. This means that it has 6 valence electrons.
