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 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 […]

How do I know if my refrigerator condenser is bad? Although a broken compressor is just one common problem with refrigerators, it can also be one of the most often overlooked, too. Your compressor kicking on and off is what you hear (or don’t hear) at various points during the day – you hear a […]

What do the arrows in a food chain represent quizlet? Food chains show which organisms eat other organisms. The arrows represent the direction of the transfer of energy from one organisms to the next. What causes the arrows to move in this direction? The earth’s rotation causes a phenomenon called Coriolis effect. The lower latitudes […]

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? 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? 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? 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 […]

Which angle of light will heat the wood the most? 90° angle Why can you see objects placed under a heat lamp which emits infrared radiation? Infrared waves have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption. Thus, infrared energy can […]

What is shear strength test? Shear strength measures a material’s ability to resist forces that cause the material to slide against itself. A universal test machine is used to apply the tensile or compressive load to determine the overall strength of the adhesive once the samples are pulled or pushed apart. … Why is shear […]
