In one publication, the author implanted biomaterials subcutaneously in rats to test the biocompatibility of materials. At a few

time points, the animals were sacrificed and the author performed H&E staining on the tissue samples. The thickness of fibrous capsule layer was then measured by calculating the average width between the two dash lines in a few H&E images of the same sample but different sections. What is the major problem of this measurement? (10 points)

Answer:

That the material can be mixed with the original tissue

Explanation:

The biomaterial has the idea to be mixed with the original tissue, due is going to grow (if it is based in cells) or is going to attach to the biological tissue, so the H&E method can be confused. The hematoxylin is going to stain the nuclei of the cells meanwhile the eosin is going to stain the extracellular matrix and cytoplasm, so, if the biomaterial is mixed in the original tissue, can be confused the exactly boundary among the biomaterial and the biological tissue.

Hope this info is useful.

svlad2 [7]

Answer:

Alternation of generations (also known as metagenesis) this type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that will have distinct haploid sexual and diploid asexual stages. A multicellular haploid gametophyte with n chromosomes alternates with a multicellular diploid sporophyte with 2n chromosomes is form in these group, made up of n pairs.

A mature sporophyte will produces haploid spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n.

In the haploid cell the spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes.
