I took this quiz and got it correct
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>

Answer:
Pericardial sac has protective tole
Explanation:
Pericardial sac or pericardium is a fibrous tissue that surrounds the heart. It has two coats:
- the outter coat-parietal pericardium
- the inner coat-visceral pericardium or epicardium which is double-layered and contains pericardial fluid between those two layers (pericardial fluid is necessary as a lubricant for the heart movement).
Besides lubrication, percardium also protects heart from infections, fixes it and limits its movements.
Answer:
Fossil Evidence and Structural evidence proves to support the theory of evolution because fossil evidence shows how animals looked like a few hundreds to thousands of years ago, and structural evidence shows how an animal can change from a land creature to a sea creator such as a whale starting from Indohyus to becoming a whale as it is now.
