Myocardial infarction or MI is also known as heart attack. This happens when the blood flow decreases due to blockage in the arteries causing ischemia in the heart secondary to poor oxygen. The symptoms include chest pain that can radiate to the shoulder,back,arm jaw and neck. This is one of the assessment finding the nurse should monitor.
Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.
Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.
Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones
Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.
Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.
Answer and Explanation:
The main environmental factors that can modify the life cycle not only of insects, but of all living beings are temperature, water availability and human activity, as variations in these factors can both prevent the life cycle from being completed, how you can accelerate and delay the phases of this cycle in different ways.
