What differentiates one amino acid from the other?
Andrews [41]

Answer: B) R group

Explanation: An aminoacid is composed by an amino group, an acid or carbonyl group and a side chain or R group, all bonded to a central carbon atom. Aminoacids are different between them for the R group and can be classified as: 1) Non-polar Neutral if the side chain is uncharged and non-polar (aliphatic or  cyclic). 2) Polar Neutral if the side chain contains amida, sulfur or hydroxyl groups. 3) Basic if the side chain contains other amino groups. 4) Acid if the side chain contains other carboxyl groups.

What is the initiator triplet in both prokaryotes and eukaryotes? Which amino acid does this triplet recruit?
gizmo_the_mogwai [7]

Methionine Aug is the initiator triplet in both prokaryotes and eukaryotes

Methionine is the specified by the codon AUG, which is also called as the start codon. Consequently, methionine is the first amino acid to dock in ribosome during the synthesis of the proteins. Tryptophan is the unique because it has the only amino acid specified by the single codon.

Methionine is one of the essential amino acid. You need to get  through your diet. It's needed to make the protein and other compounds in your body. Methionine is a amino acid. Amino acids are the building blocks thats our bodies use to make the proteins. Methionine is found mainly in meat, fish, and dairy products

Which of the following statistical measures is most helpful for indicating the extent to
Viktor [21]

Your question is lacking the necessary answer options, so I will be adding them here:

A. standard deviation.

B. mean.

C. median.

D. correlation coefficient.

E. range.

So, given your question, the statistical measure which is most helpful for indicating the extent to  which high school grades predict college grades is: D. correlation coefficient.

A statistical measure can be defined as a numerical measurement of each value of a quantitative variable in a given population. Some of the commonly used statistical measure in science include the following;

  • Mean.
  • Median.
  • Range.
  • Standard deviation.
  • Variance.
  • Mode.
  • Correlation coefficient.

Correlation coefficient can be defined as a statistical measure used for the measurement of the strength of the relationship between two (2) known variables and to represent their linear interdependence. Thus, the values of a correlation coefficient typically range from +1 (strong positive relationship) to -1 (strong negative relationship)

Hence, correlation coefficient is a statistical measure which is most helpful for indicating the extent to  which high school grades predict college grades because it would determine the strength of the relationship between them.
