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 […]
How do you know if an object has a positive or negative charge?
How do you know if an object has a positive or negative charge? An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively […]
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 […]
What are the 5 steps of the hydrologic cycle?
What are the 5 steps of the hydrologic cycle? Student Features. Many processes work together to keep Earth’s water moving in a cycle. There are five processes at work in the hydrologic cycle: condensation, precipitation, infiltration, runoff, and evapotranspiration. These occur simultaneously and, except for precipitation, continuously. Why is hydrologic cycle important? The hydrologic cycle […]
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 […]
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 […]
What are the six main structures of the central nervous system?
What are the six main structures of the central nervous system? These include structures such as the frontal and temporal lobes, the thalamus, the cerebellum, the putamen, mamillary bodies and fornix, and a convolution above the corpus callosum known as the cingulate gyrus. What are the different types of neurons of the central nervous system? […]
What are the possible values of n and ML for an electron in a 4 d orbital?
What phase are cells in when they are not dividing?
Why do I feel like passing out when I poop?
Why do I feel like passing out when I poop? But straining lowers the volume of blood returning to the heart, which decreases the amount of blood leaving it. Special pressure receptors in the blood vessels in the neck register the increased pressure from straining and trigger a slowing of the heart rate to decrease […]
