Explain why the sum of the coefficients on the reactant side of a balanced equation does not have to equal the sum of the coeffi

cients on the product side of the equation

ankoles [38]2 years ago

The requirement for a balanced equation is that the numbers of each kind of atoms in the reactants must match the number of each kind of atoms in the products.

The number of atoms in each molecule in the equation is the product of the coefficient and the subscript affixed after each element symbol in the formula to which the coefficient applies.

For example, 2 Na + Cl2 = 2 NaCl.

The coefficients on the left side total 3 but those on the right side total only 2. However, the number of atoms of each of sodium and chlorine total 2 on each side

Where should the label for the dependent variable be written for this scatter plot?
Nezavi [6.7K]

Answer:

B. Position B

Explanation:

The values for dependent variable are plotted on the y-axis (vertical) on a scatter plot. Therefore, the label for the dependent variable would be written along the vertical axis for the scatter plot, at position B.

The label for independent variable would be written along the horizontal axis for the scatter plot, at position C.

The answer is "B. Position B"

Answer 1:

The mutation shown is point mutation.

A point mutation can be described as a type of mutation in which only a single nucleotide of a sequence is either:

  • changed
  • added
  • deleted

The addition of the single nucleotide will cause the entire open reading frame to be changed. The amino acid sequence will change entirely from the position where the insertion mutation occurs. This is because the code for making amino acids works on a three base pattern. The reading of the three bases will be altered completely by the addition of just a single nucleotide.

Answer 2:

No, the resulting protein will not be altered.

The genetic code occurs in a linear sequence with triplet format. The change in a single base will cause the wrong amino acids to be formed. However, if the different code is common for the same amino acid then there will be no effect on the amino acid being formed.

<em>For example, the code GUA makes the amino acid Valine. If a mutation occurs and the code becomes GUU instead of GUA, then the resulting amino acid formed will also be Valine. Hence, there will be no alternation in the formation of the protein.</em>

Answer 3:

Melanoma cancer is the type of skin cancer which is associated with cancer from sun light. It is mainly caused due to the harmful ultraviolet rays which act as a mutagen.

<em>The mutations might keep coming back because although the growth have been removed, the other skin cells of the body might still have the mutation in them. As a result, growth will be seen again in the skin cells which might occur again and again. </em>
