Answer :
Amino acids join by forming (1) peptide bonds. Water is released.
The chains of amino acids vary according to their (2) side chains, which each have differing makeup.
These chains determine the protein’s structure and they fold to create a unique (3) third-dimensional shape.
Explanation :
Amino acid : The amino acids are the building blocks of protein. Amino acids are the compound which consist both amine 
and carboxylic 
groups along with the side chains. In the protein, many amino acids are linked by the peptide bonds.
Th peptide bonds are formed by the combining of amino group of one amino acid to the carboxylic group of another amino acid by releasing of water.
Some examples of amino acids are glycine, lysine, alanine, etc.
Peptide bond formation image is shown below.
In the image 'R' can be contained by different groups like hydrogen, methyl, phenyl, etc
Answer:
Electrons
Explanation:
When determining the chemical properties of elements, the most important subatomic particle to consider is the electrons.
Electrons are negatively charged particles that orbits an atom. They occupy the extranuclear space of an atom.
These electrons determines the chemical properties of each atom. Most especially, the valence ones. All elements wants to resemble the noble gases, so they alter their number of electrons in order to attain this stable state.
To determine the quantity of pure CaCl2 from the given amount of CaCl2.9H2O, we use the ratio of CaCl2 to CaCl2.9H2O. From the formula the ratio would 1 is to 1 We calculate as follows:
7.5 g CaCl2.9H2O (1 mol / 273.1215 g) ( 1 mol CaCl2 / 1 mol CaCl2.9H2O ) ( <span>110.98 g / 1 mol ) = 3.05 g CaCl2
Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
To start one difference between the two is that a scientific experiment is meant to be repeated and to be formed into a theory and/or a scientific law. Scientific experiments also use different types of data, for instance, you could be recording how much a plant grows in a month, in an experiment you would focus on the types of soil being used. In an investigation you would observe how tall the plant actually grew.
