Anna applies a force of 84n Nto lift her baby nephew 2.0 m. How much work<br> does Anna do? Answer
natima [27]

Answer:

168 J

Explanation:

Work can be calculated using the following formula.

w=f*d

where w is work, f is force, and d is distance.

Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.

f=84 N

d=2 m

Substitute these variables into the formula.

w=84 N* 2 m

Multiply

w=168 N-m

A N-m is the same as a Joule, or J.

w= 168 Joules

Anna does 168 Joules of work.

The shape of a protein molecule is influenced by
Rus_ich [418]

Answer:

The answer is C. its sequence of amino acids.

The protein's shape is influenced by its sequence of amino acids or primary structure.

Explanation:

The primary structure of a protein molecule is dependent on the amino acid chain sequence it has. The amino acid chain's <u>linear</u> structure is composed of <u>covalently bonded</u> amino acids via peptide bonds. This serves as the <u>overall backbone </u>of the protein.

<h3>Additional notes: </h3>

Secondary structure of protein

It defines the 3-dimensional shape of the<u> locally folded polypeptide</u>. They come in two forms, the alpha helices and beta sheets. During the formation of the primary structure, acidic and basic amino residues may cause kinks and turns, re-configuring the 3-D shape of the local polypeptide.

Tertiary structure of protein

This determines the overall 3-dimensional structure of the protein. The structure is due to the <u>linking of the R groups</u> of the related amino acids, <u>hydrophobic bonds</u>, and <u>disulfide bonds</u>. These bonds are <u>highly stable</u> and are not easily changed or destroyed.

Quaternary structure of protein

It is a structure that consists of multiple folded polypeptide chains or subunits. This allows the protein to have m<u>ultiple functions</u>. <u>Non-covalent forces</u> keep these structures together, making it <u>prone to rapid conformational changes.</u>
