Is bioimpedance analysis accurate?

Is bioimpedance analysis accurate? BIA is considered reasonably accurate for measuring groups, of limited accuracy for tracking body composition in an individual over a period of time, but is not considered sufficiently precise for recording of single measurements of individuals. What does bioimpedance analysis measure? Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method […]

How do molluscs see?

How do molluscs see? They found that mineral lenses have pretty good resolution, but each eye is so tiny that there are only about 100 cells in the retina. Each retinal cell would act like a pixel on a computer screen, so the mollusc would see an extremely pixelated image with each of its eyes […]

What are two examples of opportunistic species?

What are two examples of opportunistic species? Opportunistic organisms commonly refer to animals and plants that tolerate variable environmental conditions and food sources. Some opportunistic species can thrive on almost any available nutrient source: omnivorous rats, bears, and raccoons are all opportunistic feeders. What are examples of pioneer species? Plankons, fungi, bacteria, lichens etc. are […]

What is the principle of turbidity meter?

What is the principle of turbidity meter? An infrared diode irradiates infrared light into the media. Particles in the media reflect the irradiated light which is detected by the receiver diode (backscatter principle). The electronics calculate the relative turbidity of the media according to the received signal. What is Jackson turbidity Unit? The alternatively used […]

Do viruses have mitochondria?

Do viruses have mitochondria? Generally, viruses manipulate host metabolism by re-orchestrating organelle structure and functions. As mitochondria has multifaceted roles in controlling cellular metabolism and immune responses, it is not surprising that several (+)ssRNA viruses target mitochondria. What organelles do viruses have? Viruses do not have nuclei, organelles, or cytoplasm like cells do, and so […]
