Why is cellular respiration necessary for living organisms? Why are several chloroplasts in the plant cell? Why do epithelial cells reproduce rapidly? Why are stem cells necessary for cell differentiation? Why should plants require both chloroplasts and mitochondria? Can they live without either one?
Why is cell differentiation important in multicellular organisms? Why are endothelial cells important? Why aren't chloroplasts in animal cells? Why is it essential for a eukaryotic cell to compartmentalize its functions? Why are cells alive but macromolecules are not?
What is the function of the Histopathology Section of the laboratory? The primary function of the Histology/Pathology Laboratory isto evaluate specimens for the absence or presence of neoplasia; however, other conditions may also be diagnosed cytologically. Cellular preservation, important to the micros...
Finally, we maintain that 'sex sameness' is as important as 'sex differences' when building a complete understanding of biology for both males and females and provide a framework with which to classify and guide investigation into the mechanisms mediating sex differences and sex sameness. 展开 ...
However, since the meristem confers plant growth and cellular differentiation, it has a high energy demand. Therefore, its mitochondria should not be protected from reactive oxygen species. Also, the hypothesis cannot apply to unicellular organisms. Thus, like most of the genetic model...
aThe transforming acidic coiled-coil (TACC) protein family has an important role in various cellular events, such as cell proliferation,growth, differentiation and gene regulation through a direct or indirect association with molecules involved in the centrosome–microtubule network, transcription and mRNA...
Metabolic evaluation of cellular differentiation of tobacco leaf explants in response to plant growth regulators in tissue cultures using 1H NMR spectrosco... initiated by either auxins or cytokinins, which is reflected by similar metabolic changes produced by the two distinct PGRs during the initial ...
The hypothesis is plausible because in the suborder of rodents, the Castorimorpha, the two extant species of beaver are grouped with the true gophers and kangaroo rats, neither of which has webbed feet. The adaptability of the organism is also likely to have had an important role in ...
Ovarian cancer is a very complicated disease divided into epithelial cell cancer subclasses and germ cell cancer subclasses, and it gets even more complex, considering the cellular differentiation of each cancer. However, people talk about ovarian cancer as if it is a single disease with the same...
Why is programmed cell death important? Why must cells absorb energy and nutrients? How are stem cells necessary for cell differentiation? How do B cells make antibodies? What is the importance of aquaporin in a red blood cell? Why is cellular respiration important to the biosphere?
