High blood and urine glucose (sugar) is characteristic of a disorder called ____________.
aleksklad [387]

Answer:

Is characteristic of Diabetes.

Explanation:

Diabetes is a disorder in which blood sugar increases due to the fact that there is mechanism by which sugar enters the cell is somehow affected.

There are different types of this disorder, the most common ones are the following,

1. Diabetes type 1, is an autoimmune disorder in which the cells that are in charge of producing insulin are destroyed, as a consequence there is not enough insulin (responsible for allowing the glucose channels to open and transport glucose into the cell). Therefore, sugar remains in blood circulation. When glucose levels are too high, it starts filtering through the kidneys and ends up in the urine.

2. Diabetes type 2, is triggered by different factors, there are genetic and environmental factors that trigger this disease. In this case, cells are 'resistant' to the insulin effect, so the body reacts by secreting more insulin. As a consequence, cells in charge of secreting insulin are overworked and at the same time, the body cells keep on increasing the resistance to insulin. There is a point in which this compensation fails to work, and blood sugar rises. When the levels become high, glucose starts filtering through the kidneys and ends up in the urine.

There are more types of diabetes, such as gestational diabetes or LADA. In this cases the cause of the disease varies, but the outcome is the same, increased blood glucose levels and presence of glucose in the urine.

Discuss Clonal Selection Theory in human physiology and its application in Rubeola Infection in a 6-year-old child.
Illusion [34]

Answer:

Application or Implementation including its Clonal personality psychology for Rubeola infectious disease in something like a 6-year-old child is given below.

Explanation:

<u>Clonal Selection Theory:</u>

This hypothesis notes that lymphocytes have virulence genes preceding activation and also that spontaneous mutations throughout clonal expansion induce the formation of lymphocytes containing strong affinity antigen affiliations.

<u>Its applications are given below:</u>

  • Throughout the situation of Rubeola infectious disease in such a 6-year-old boy, as shown by this hypothesis, B-cells that distinguish after such an innate immune system forming phase selection because then antioxidants formed by younger memory B cells provide significantly higher commonalities to certain antigens.
  • As a result, secondary physiological systems from memory blocks have become so successful that persistent Rubeola attacks with much the same virus are prevented unless setting up.
  • After the primary outbreak, genetic mutations throughout clonal selection may generate recollection B cells which could attach to implementation more effectively than those of the initial B cells.
