Answer: Container P.
Explanation: All of the containers started at 30 degrees, and they all lost heat, as shown in the table. However, Container P saw the smallest decrease in temperature. This means that Container P was most effective at preventing heat transfer from the water to the environment.

17. Which of the following best describes how amino acids affect the tertiary structure of a
protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.
Answers
Answer:
It is B
Explanation:
I had this question on my test last week
The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).
An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.The linear sequence of amino acids within a protein is the primary structure of proteins. The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.The most common tertiary structures of the proteins are globular and fibrous structures.Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

ATP is a storable form of energy, while glucose is a usable form of energy.
ATP is only a usable form of energy, but glucose can be used and stored.
Glucose is only a storable form of energy, but ATP can be used and stored.
Answers
The main difference between glucose and ATP is that Glucose is a storable form of energy, while ATP is a usable form of energy.
Glucose is storable form of energy because it can't be used as energy until it can be broken down by mitochondria of the cell while on the other hand, ATP is the usable form of energy which we can get from the break down of glucose molecules. Our cells use ATP as a fuel to do various activities of the cell so we can conclude that in glucose, energy is present in stored form whereas ATP is used as energy in various activities.

If energy is released, free energy must be what?
Answers
Answer:
If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.
Explanation:
Hope it helped!
Answer:
If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.
