What percentage of drug research is funded by the government? For the first time in the post–World War II era, the federal government no longer funds a majority of the basic research carried out in the United States. Data from ongoing surveys by the National Science Foundation (NSF) show that federal agencies provided only 44% […]
What causes altocumulus?
What causes altocumulus? Altocumulus clouds usually form by convection in an unstable layer aloft, which may result from the gradual lifting of air in advance of a cold front. The presence of altocumulus clouds on a warm and humid summer morning is commonly followed by thunderstorms later in the day. What is the characteristic of […]
What do you mean by hydraulic?
What do you mean by hydraulic? Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Where are hydraulic […]
How do you make a simple electromagnet?
How do you make a simple electromagnet? Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire. The electric field in the wire coil creates a magnetic field around the nail. In some cases, the nail will remain magnetised even when removed from within the wire coil. […]
What are 3 products of the light-dependent reactions?
What are 3 products of the light-dependent reactions? The products of the light-dependent reactions, ATP and NADPH, have lifespans in the range of millionths of seconds, whereas the products of the light-independent reactions (carbohydrates and other forms of reduced carbon) can survive for hundreds of millions of years. What is importance of light? It seems […]
Is parsec is a unit of Time?
Is parsec is a unit of Time? Unfortunately, like the similarly misused ‘light-year’, the parsec is a unit of length, not of time. A parsec is equal to about 3.26 light-years or roughly 31 trillion kilometres (19 trillion miles). The unit has its origins in one of the first methods of determining the distance to […]
Why do plants look green in color 10?
Why do plants look green in color 10? Answer: The leaves of plants contain green pigments called chlorophyll which is necessary for photosynthesis. Plants reflect green light of sunlight, so they look green. Why are some plants not green in Colour? When leaves contain high concentration of anthocyanin pigments, the leaves appear red or purple […]
What is the significance of reference point for measuring distance?
What is the significance of reference point for measuring distance? A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a […]
Can mitosis ever be used for human reproduction?
Can mitosis ever be used for human reproduction? In single-cell organisms, mitosis is the only form of cellular reproduction. One round of mitosis yields two genetically identical cells. This is classified as asexual reproduction because it does not require sex for the creation of new organisms. What cells does mitosis not occur in? You read […]
What is the electromagnetic spectrum used for?
What is the electromagnetic spectrum used for? Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Which color is the most refracted? violet light What is required for refraction? For refraction to occur […]
