Answer:
hey discover an
interesting pattern in the
world that no one else
has described, but they
cannot explain what is
causing the pattern?
Explanation:
Given what we know, we can confirm that since Mr. Summers has to test a hypothesis, his next step should be to design an experiment.
<h3>Why design an Experiment?</h3>
- The next step is to design an experiment.
- This is because Mr. Summers has already made an observation and created a problem.
- He must now gather data to be analyzed.
- In order to do this, he must first design and perform an experiment.
Therefore, we can confirm that Mr. Summers must design an experiment given that this is the best way to gather data in order to be analyzed in the future and draw a valid conclusion.

Answer:
Primary structure is the correct answer.
Explanation:
- The primary structure is the simple level of protein structure.
- Primary structure is a basic amino acids sequences in a protein.
- In the primary structure, amino acids are attached together by a covalent bond.
- Primary structure is when the amino acids are joined together with peptide bonds to produce polypeptide chains
- Changes in pH are least likely to change the amino acid sequence or disrupt peptide bonds.
Explanation:
Answer:
The physical and chemical properties of the product do not match the properties of the reactant.
Explanation:
Chemical change:
The changes, that occur due to change in the composition of a substance and result in a different compound is known as chemical change.
These changes are irreversible
These changes occur due to chemical reactions
These may not be observed with naked eye
Example:
Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood
Boiling of egg: that change the chemical composition of protein in the egg .
The reaction of Hydrogen and oxygen:
H 2 (g) + O 2 (g) -------------------------------------> 2H 2O (l)
The reaction between sugar and oxygen form a product which is different from the reactant that's why it indicate the occurrence of chemical reaction.
While in case of physical changes just state of matter are changed. Properties remain same.
