Explain the basis for the great diversity of proteins in living organism.
sashaice [31]

Answer:

Explanation:

Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

How does sulfur in the air get moved to the soil.
Andrew [12]

Answer:

Sulfur can also fall directly from the atmosphere in a process called fallout. Also, the weathering of sulfur-containing rocks releases sulfur into the soil. These rocks originate from ocean sediments that are moved to land by the geologic uplifting of ocean sediments.

If you know you have 32% adenine you can figure out the percent of cytosine? <br> please hurry
Ad libitum [116K]

Answer: 18%

Explanation:

Use Chargaff's rules which states that 100% is total of all 4 bases and Adenine and Thymine need to have 1:1 ratio and Cytosine and Guanine need to have 1:1 ratio

32% Adenine = 32% Thymine

32 + 32 = 64 100 - 64 = 36 36/2 = 18

18% of Cytosine and 18% of Guanine

The registered nurse is teaching a nursing student about care for a patient who is on oral warfarin therapy. Which statement mad
Paraphin [41]
<h2>1) option is correct </h2>

Explanation:

  • Aspirin is contraindicated in a patient who is on oral anticoagulant medication because aspirin intensifies the action of the anticoagulant, which results in bleeding
  • Bleeding from shaving cuts may be difficult to control, so the patient should be advised to use an electric razor only
  • Patients who are on oral anticoagulant medication have difficulty controlling bleeding from injuries or external hemorrhage
  • The nurse should teach the patient techniques such as the application of pressure to control bleeding
  • Dental extraction may cause bleeding, which may be uncontrollable for a patient who is on anticoagulant medication, so patients on such type of medication should inform the dentist before starting the treatment
