What is a Sharks sixth sense called? A Shark’s Sixth Sense around their head called ampullae of Lorenzini. These are jelly filled pores that go down to the nerve receptors at the base of the dermis. They are specialized electroreceptor organs that allow the shark to sense electromagnetic fields and temperature changes in the water […]
Who has proved that oxygen evolved in photosynthesis comes from water?
Who has proved that oxygen evolved in photosynthesis comes from water? Cornelius van Niel Which light range is most effective in photosynthesis? The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the […]
Is 1500 watts a lot of electricity?
Is 1500 watts a lot of electricity? Most electric heaters use 1,500 watts, but some are slightly less or slightly more. Since 1,000 watts equals 1 kilowatt, that means your heater uses 1.5 kilowatts of power. However, your electric bill is measured in kilowatt hours, which is the amount of energy used while running a […]
Do astronomers use chemistry?
Do astronomers use chemistry? By comparing astronomical observations with laboratory measurements, astrochemists can infer the elemental abundances, chemical composition, and temperatures of stars and interstellar clouds. Do you need chemistry for astronomy? Astronomy is a unique subject because it deals with such a vast mixture of topics – the very reason why many people find […]
Does your little toe help you balance?
Does your little toe help you balance? Your toes play an important role in keeping you balanced as you move, whether you’re barefoot or wearing shoes. Your pinky is the smallest toe, but it’s crucial in helping you to maintain your balance. It helps to think of your foot as having a triangular base of […]
Are the layers still horizontal or are they bent Why?
Are the layers still horizontal or are they bent Why? Answer. Answer: Figure 10.6: Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. How is horizontal unconformity formed? An angular unconformity is an unconformity where horizontally parallel strata […]

Why is gravity a non-contact force?
Why is gravity a non-contact force? Magnetism is an example of a non-contact or action-at-a-distance force. These are forces which can act on an object without being in physical contact with it. The force of gravity is another example. Thus, gravity will pull a raindrop down to Earth without any tangible physical link between the […]
How does heat transfer from one object to another and why does it generally flow from the hotter the colder object?
How does heat transfer from one object to another and why does it generally flow from the hotter the colder object? Thermal conduction involves energy in the form of heat being transferred from a hot region to a cooler region through a material. At the hotter end the atoms, molecules, and electrons vibrate with more […]
