Why is a parent usually a better match for transplanted tissue to a donor than a random individual of the same species?

s344n2d4d5 [400]

Answer: For decreased chances of rejection

Explanation:

The three higly polymorphic MHC 1 genes in human beings are HLA-A, HLA-B and HLA-C.

These determine the compatibility of the organ or tissue in the recipient's body each by the help of many alleles that segregates in a population.

There are very less chances that a random chosen donor will match the a recipient six allele genotype.

This is the reason parent may be the best donor for organ transplantation or tissue transplantation.

Which of the following statements about carotenoids is NOT true? Carotenoids include red, orange, and yellow pigments. Carotenoi

kvv77 [185]

The right answer to this question is option D. Carotenoids are categorized into two major divisions: carotenes and beta carotenes

First, let's check option A, it says that the carotenoids include red, orange and yellow pigments, that's true, we can check that on lab for example, a vegetable that can be mentioned here are carrots, it has lots of this and it's very healthy too, and remember, there isn't a single animal that can produce carotenoids, so they need to grab it from nature.

The second option, B. says that sometimes carotenoids are sometimes called as acessory pigments, that's true too, some studies consider them acessory pigments, so, they're not alone there, there are different kinds of pigments that can be on that plant, and they're also very important for the animals. Option C refers to beta carotene as the most abundant carotene in plants, that's true too, we can also find other kinds of carotenoids on plants, but this one as it's seen in lab, is the most common one. The last one, D, isn't true, the two major divisions are: Xanthophylls and Carotenoids, beta carotenoids are a type of carotenoids, not a different group.

Which of the light micrographs shows epithelial tissue that forms thyroid gland and secretes hormones?

ruslelena [56]

The Simple cuboidal epithelium forms thyroid gland and secretes hormones is shown in the picture attached.

Its main functions are secretion and absorption. It has an abundance of organelles to facilitate active transport frequently found in glands, such as salivary glands, the thyroid gland, and the pancreas, where its function is secretion.

The epithelial cells tend to be cubical in form after they are inactive, however additional columnar after they are actively secreting hormones.
The epithelial cells accumulate iodine from the blood and use this component within the synthesis of thyroglobulin, an oversized compound protein that forms the mixture.
