Explanation:
For a man weighing 185 pounds his minimum daily protein requirement is <u>67.118 g </u>of protein.
Proteins are integral to many bodily functions including cell growth,repair and as an alternative source of energy.
Further Explanation:
Large monomer chains form biological macromolecules that perform many essential body functions, including nucleic acids, carbohydrates, proteins, and lipids. These are organic molecules, meaning Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N), and phosphorus (P) are ringed or long-chain.
Proteins are structural support molecules consisting of long amino acid chains joined via peptide (CONH) bonds; these are 20 specific units arranged into several macromolecules. Amino acids are absorbed through digestion and incorporated into the cells of the body to form muscle organs that signal molecules and provide an alternative source of energy.
- First... convert 185 pounds to kilograms. Pounds (lbs) can be a measure of mass or weight, while Kilograms (kg) are a measure of mass.
- 1 pound= apprx 0.4535 kilograms. ∴ 185 lbs = 83.8975 kg
- Then, find the daily requirement for the person's mass in kg .....................<em>0.8 grams (g) of protein is recommended per kg of body weight. </em>∴ 0.8 × 83.91 = <u>67.118 g</u>

A.chromosomes aligning themselves at the equator.
<h3>What distinguishing features of mitosis' metaphase?</h3>
A phase of cell division known as "metaphase" (mitosis or meiosis).Individual chromosomes are typically dispersed throughout the cell nucleus.The chromosomes of the cell condense and move toward one another, aligning in the center of the dividing cell, and the nucleus of the cell disintegrates during metaphase.
<h3>What distinguishes metaphase from other phases?</h3>
Its alignment of a duplicated chromosomes at the metaphase plate, an equatorial plate, is what gives metaphase its name.Via microtubules attached to its kinetochore, one of the sister chromatids is joined to one pole of the cell, and the other sister chromatid is associated to the other pole.
