Answer: Components of cell junctions
Explanation:
<u>Fibroblasts are cells located in the dermis,</u> responsible for the formation and remodeling of tissue. They synthesize fibers and maintains the extracellular matrix of the tissue of animals. So, t<u>he extracellular matrix is a structurally complex entity that surrounds and supports the cells found in tissues</u>.
A cell junction a structure that exists within the tissues of animals and they consist of protein complexes that provide contact between cells or between a cell and the extracellular matrix. So if the cells do not appear flattened and do not attach to the extracellular matrix, then there is a problem with the components of cell junctions, which are mostly proteins as it was said before. And since proteins are coded by genetic information stored in DNA, then if there is a mutation in any of those genes, the fibroblast will fail to attach because the protein of the cell junction will be abnormal.
The red-green color blindness is a recessive X-linked trait. The females are not affected unless both the X chromosomes have the affected allele. Mostly, the females are the carriers, and the males are affected as they have only one X chromosome. In the given pedigree, the father of Irene have the normal allele, while her mother is a carrier. However, Irene is neither a carrier nor affected. This means that she carries normal alleles on both X chromosomes. Hence, her allele combination is
.
As an organism evolved an ability or physical characteristic, another organism which evolved the ability to mimic that trait would have a higher chance of survival and could pass on its genes
Answer:
1. Location: Histosols are the soils which are found in the grasslands, swamps and marshes, whereas the aridosols are soils that are found in desert regions.
2. Color: Histosols are soils which are rich in organic matter therefore, are dark colored, whereas the aridosols are soils that lack organic matter, hence are light in color.
3. Water retention capacity: Histosols exhibit higher water retention capacity as compared to the aridosols.
4. Rate of decomposition: Rate of decomposition is higher in the histosols as compared to aridosols.
