Which wavelengths of light drive the highest rate of photosynthesis select the two best answers? An action spectrum plots the rate of photosynthesis at various wavelengths of visible light, and it shows that blue light with a wavelength of about 490 nm is effective in driving photosynthesis. Which wavelength of light is best absorbed by […]
What are the two basic functional units of the nervous system?
What are the two basic functional units of the nervous system? Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. What is the functional unit of brain? It is also proposed […]
Why does NASA study asteroids?
Why does NASA study asteroids? Thus the study of asteroids is not only important for studying the primordial chemical mixture from which the Earth formed, these objects may hold the key as to how the building blocks of life were delivered to the early Earth. On a daily basis, the Earth is bombarded with tons […]
What are main components of air?
What are main components of air? The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). Higher in the atmosphere air also contains ozone, helium and hydrogen. Is granite a pure substance? Granite is […]
What type of inspection can determine delamination damage of a composite structure?
What type of inspection can determine delamination damage of a composite structure? A basic and useful part of inspection on composite structures is a visual inspection. The inspector looks for visible signs of damage to the structure like burns, disbonds, and delaminations. What test should follow a tap test if delamination damage is found? If […]
How do you increase the coefficient of convective heat transfer?
How do you increase the coefficient of convective heat transfer? Generally Heat transfer coefficient of fluid increases with the increase in Reynolds number or velocity of fluid when it flows through a pipe. Why does flow increase heat transfer? Heat transfer coefficient is the ability of fluid to transfer heat when it comes in contact […]
Why does an egg not break when dropped on grass?
Is a solution with a pH of 12.0 acidic or basic?
What are three trends on the periodic table?
What are three trends on the periodic table? Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element’s properties. Which property of elements increases as you move across […]
How can you tell if someone is heterozygous or homozygous for a dominant trait?
How can you tell if someone is heterozygous or homozygous for a dominant trait? If the test cross results in any recessive offspring, then the parent organism is heterozygous for the allele in question. If the test cross results in only phenotypically dominant offspring, then the parent organism is homozygous dominant for the allele in […]
