How to have thousands of different proteins where there are only 20 different amino scids?

Answers

The answer to this query is that the 20 amino can be combined and/or arranged in a particular order in a million different ways to form different proteins.Protein molecules are often quite large and are made up of hundreds to thousands of amino acids. The human body has about 100,000 different types of proteins.There are hundreds of different amino acids and out of these 20 are essential for the body. It is from these 20 that the proteins of the body are made.How it is possible to make so many different types of protein is dependent on the fact that it is not only the type of amino acids in a protein that determine its function, but also the order in which they are placed. In a protein with 1000 amino acids, a single amino acid placed in a different place will change that protein to an entirely different conformation and subsequently an entirely different function.

When caring for a client with a chest tube and water-seal drainage system, the nurse should?

Answers

Measuring and documenting the drainage in the collection chamber-rationale: the nurse should regularly measure and document the amount of chest tube drainage to detect abnormal drainage patterns, such as may occur with a hemorrhage (if excessive) or a blockage (if decreased). continuous bubbling in the water-seal chamber indicates a leak in the closed chest drainage system, which must be corrected. the nurse should keep the collection chamber below chest level to allow fluids to drain into it. the nurse shouldnt strip chest tubes because doing so may traumatize the tissue or dislodge the tube

Stress often causes muscles toA. contract and tighten.
B. bruise more easily.
C. resist exercise.
D. increase in pain.

Answers

The answer is letter A.

Stressoften causes the muscles to contract and tighten. This happens becauserelatively high amounts of hormones that are stress-related are released in theblood. This then causes the muscles to contract and tighten causing cramps anduncomfortable feelings in an individual. Stress-related stimulus that occursmostly within the brain, triggersa response in the muscle contractions causing it to excessively contract andtighten. An individual issuggested to perform deep breathing exercises and stretches to reduce thetightness in the muscles and to calm the nerves to return to its normal state.
Stress often causes muscles to contract and tighten because stress makes people frustrated and also makes a person look older than they are.
