What happens when you increase Focal Length? If you increase the focal length then the size of the image on the film or sensor will increase i.e. the image will be magnified compared to a lens of shorter focal length. The power of a lens is inversely proportional to its focal length, being equal to […]
Why nitrogen-fixing bacteria are important?
Why nitrogen-fixing bacteria are important? Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle. Why can’t plants fix nitrogen? Earth’s atmosphere contains a huge pool […]

What is laminar mixing?
What is laminar mixing? Laminar mixing processes are based on the repeated separation of the flow into layers, followed by redistribution and recombination parallel to the flow direction. The number of layers, and hence the homogeneity, increases with each additional mixing element. What does turbulent flow cause? Turbulence increases the energy required to drive blood […]
What are the strongest and weakest bonds?
What are the strongest and weakest bonds? This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” What is […]
