In the experiment, SpongeBob is the control group because regular lotion is used instead of the muscle cream. This allows a comparison with Patrick(rightly known as the experimental group) who uses the special muscle cream.
In the given scenario, SpongeBob represents the control group. In any experiment, the control group is the one that is kept normal or unchanged to be able to compare the effects of the variable being tested. In this case, it's the use of the special muscle cream. Patrick, whose arms and back are lathered with the muscle cream before each session, represents the experimental group because he is exposed to the variable being tested, which is the muscle cream. On the other hand, SpongeBob, who is given regular lotion instead of the special muscle cream, is part of the control group because he helps to provide a baseline for comparison.

d. quaternary .
The specific spatial arrangement of amino acid residues that are close to each other in the polypeptide chain is called the tertiarystructure of a protein.
Protein structure is three dimensional in shape, where the atoms are arranged in amino acid chain. The chain is polypeptide containing many amino acid sequences.
The tertiary structure have a single polypeptide chain which is called the backbone.
Therefore, the specific spatial arrangement of amino acid residues that are close to each other in the polypeptide chain is called the tertiarystructure of a protein.

Answer:
c. tertiary.
Explanation:
In this case, we can review the definition of each level of structuration in the proteins:
Primary structure
In the primary structure, the amino acids are linked by peptide bonds. That is, the order of the amino acids is the criterion that defines this type of structure.
Secondary structure
In the secondary structure, we have to look at the way in which the protein is folded. The options are:
-) Beta-laminar: A structure in which the protein has a planar shape.
-) Alpha-helix: A structure in which the protein has a cross-strand form.
Tertiary structure
In the tertiary structure, the R groups that the amino acids have in the primary structure can generate interactions with each other. Interactions such as hydrogen bridges, dipole-dipole, hydrophobic interactions. This makes the protein have a very specific three-dimensional structure, on which its function depends.
Quaternary structure
In the quaternary structure, several subunits may be attached, or there may be prostatic groups (metals that can help to attach various protein units).
With all these in mind, the deffinition that fits with the description in the question is the tertiary structure.

Answer :
(i) The value of equilibrium constants for this reaction is, 10
(ii) The value of equilibrium constants for this reaction is, 0.1
Explanation :
The given equilibrium reaction is,
Now we have to determine the equilibrium constants for the following equilibrium reactions.
(i)
From the given reaction we conclude that, the reaction (i) will takes place when the given main reaction will be multiplied by half (1/2). That means when reaction will be half then the equilibrium constant will be:
The value of equilibrium constants for this reaction is, 10
(ii)
From the given reaction we conclude that, the reaction (ii) will takes place when the reaction (i) will be reverse. That means when reaction will be reverse then the equilibrium constant will be:
The value of equilibrium constants for this reaction is, 0.1
Answer:
3056.25g
Explanation:
Problem here is to find the mass of Cu(NO₃)₂ to weigh out to make for the number of moles.
Given;
Number of moles = 16.3moles
Unknown:
Mass of Cu(NO₃)₂ = ?
Solution:
To find the mass of Cu(NO₃)₂, use the expression below;
Mass of Cu(NO₃)₂ = number of moles x molar mass
Let's find the molar mass;
Cu(NO₃)₂ = 63.5 + 2[14 + 3(16)]
= 63.5 + 2(62)
= 187.5g/mol
Mass of Cu(NO₃)₂ = 16.3 x 187.5 = 3056.25g
Answer:
Explanation:
Hello,
In this case, considering that 1 m equals 10 dm, the required diameter of the atom in decimetres is:
Best regards.
The diameter of an atom is approximately 1 * 10^-10 * m, which translates to 1 * 10^-11 decimeters by multiplying the meter measurement by 10.
The subject of this question is a unit conversion. We are trying to convert the diameter of an atom from meters to decimeters.
The process is as follows:
In essence, to convert meters to decimeters, we need to multiply the meter measurement by 10. But because the meter measurement of the atom is in the power of -10, the decimeter equivalent would be in the power of -11.

What is the molarity?
Answer: The concentration of is 0.0122 M.
Explanation:
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
We are given:
Putting values in above equation, we get:
Hence, the concentration of is 0.0122 M.
