Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
Answer:
Soil living organisms compromise from mammals (such as rats) to micro organisms (such as nematodes and protozoa). Soil organisms help in the modification of soil, and also in the decomposition of organic matter. However they can also pose as a treat to to some crops, as they are responsible for some plant diseases.
Explanation:
When living organisms breathe they give out carbon dioxide gas as a waste product. Carbon dioxide gas can be detected (identified) using a carbon dioxide indicator solution called bromothymol blue. To find out if there are living organisms present in the four different levels of soil takenfrom the deciduous forest.
Answer is only 1st case that is homozygous zygote is the right answer.
Explanation:
In maternal recessive mutation both the alleles are mutant and exhibit mutant phenotype. The mutated alleles are present as homozygous.
From the definition it is concluded that:
first case, homozygous zygote is mutant phenotype
second case, heterozygous zygote not mutant phenotype
in third case, heterozygous zygote not mutant phenotype.
