Answer:
The correct answer is "each of the MHC genes has a large number of alleles, but each individual only inherits two for each gene".
Explanation:
In normal conditions, an individual has only two different alleles for a given gene: one inherited from his mother and the other from his father. However, this does not mean that among humans, there are only two different alleles for each gene. The major histocompatibility (MHC) genes are a clear example of this, since there are multiple combinations for each MHC class. For instance, there are 40 very similar alleles only for the HLA-B27 subtype.
Answer:
According to the model, the "villi" of small intestines is being damaged as an impact of celiac disease. Small intestines are responsible for absorption of nutrients and minerals from food, this occurs through villi, in case of damaged villi absorption is interfered, thus disturbing the digestive system. If the nutrients, minerals or vitamins are not being absorbed well by small intestines then they will be excreted out of the body and will not be transported to the blood and other areas, this would result in deficiency of minerals and vitamins in blood that cause weakness.
Percent error is a statistical tool used for evaluating precision. It is expressed as:
Percent error = | (experimental value - theoretical value) / theoretical value | x 100%
Experimental value represents the calculated value while the theoretical value represents the known value. A percent error value which is approaching zero means that your experimental value is close to the known value. Which can possibly mean that you have precise measurements. Calculations are as follows:
Percent Error = | (2.54 - 2.70) / 2.70 | x 100 =5.93%
Thus, the answer is b. 5.93%.
