Why is telomerase not active in somatic cells? Why do some cells have more mitochondria? Why do cells spend most of their life in interphase? Why do epithelial cells have many mitochondria? Why aren't chloroplasts in animal cells? Why do cells have organelles?
T-tubules have been studied in cardiac myocytes, isolated from multiple animal species such as mouse, rat, and rabbit as well as bigger mammals – dog, sheep, pig, and human. Across these species, it is well accepted that t-tubules form an extensive and well-organised network in the ventr...
Do human cells have cilia? What are cuboidal cells? Which molecules can easily pass through cell membrane without help of carriers? What does the cuboidal epithelial tissue absorb and what does it diffuse? What do amacrine cells do? What is the function of ciliated epithelial tissue?
…the plant body,retain their protoplasts(the cytoplasm, nucleus, and cell organelles) that carry out these functions. In plant cells the protoplast, or living material of the cell, contains one or more vacuoles, which are vesicles containing aqueous cell sap. How do spheroplasts and protoplasts...
Do humans have cell walls? Human cells only have a cell membrane. The cell wall is primarily made of cellulose, which is composed of glucose monomers. As the outermost layer of the cell, it has many important functions. Why Animal Cell has NO Cell Wall?
Female Student: Actually, well, if it doesn't have organelles, I mean DNA or whatever. Then what happens if the lens is damaged or something? Professor: And that's the problem, the price of clear vision of transparent lenses is that the lens fibers can't regenerate or repair themselves,...
167 C. bantiana is clearly neurotropic, as evidenced by central nervous system involvement in 26 of 30 culture-confirmed human infections in one series168 and confirmed by animal studies.169 Other dematiaceous fungi that have been implicated include Ramichloridium mackenziei (exclusively in the ...
Fluorescent bacteria and yeast particles have been employed in a variety of published studies using fluorescence microscopy, quantitative spectrofluorometry, and flow cytometry (Figure 4). These include the detection of yeast phagocyto...
Do prokaryotic cells have a nucleus? Learn the answers to questions like: what do prokaryotic cells have instead of a nucleus, and do prokaryotic cells have DNA. Related to this Question Do human cells have RNA? What RNA subunits are ribosomes made of in prokaryotes and eukaryotes?
Why do cells in your body differ from each other? How are hybridoma cells produced? What is the role of microfilaments in cell division? Why do cellular organelles have different structures? Describe the process of cell division by mitosis. ...
