Why do you think groundwater investigation is important? The viability of groundwater sources and exploitation methods depend on the water quality. Therefore, investigation of groundwater quality and result assessment and interpretation are very important in deciding management policy. What is groundwater monitoring? Typical groundwater monitoring wells are used to enhance environmental protection at landfills. WM […]
Do plants and animals have a rough ER?
Do plants and animals have a rough ER? Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes. What is the function of RER and SER? Difference between Smooth and […]
How do you find atoms in aluminum foil?
How do you find atoms in aluminum foil? To determine the number of atoms thick the foil was, dimensional analysis was used to convert the centimeter thickness to number of atoms. To determine the number of atoms in the whole piece of foil, the volume of the foil was converted to atoms using dimensional analysis. […]
Is nuclear binding energy positive or negative?
Is nuclear binding energy positive or negative? Nuclear binding energy is the energy required to split a nucleus of an atom into its component parts: protons and neutrons, or, collectively, the nucleons. The binding energy of nuclei is always a positive number, since all nuclei require net energy to separate them into individual protons and […]
Why does NASA use metric?
Why does NASA use metric? The agency has decided to use metric units for all operations on the lunar surface, according to a statement released today. The change will standardize parts and tools. It means Russian wrenches could be used to fix an air leak in a U.S.-built habitat. How much would it cost for […]
How is the largest portion of sediment in streams carried?
How is the largest portion of sediment in streams carried? For example, a flooding river is muddy and discolored from the large amounts of sediment suspended in the water. The suspended load is generally made up of lighter‐weight, finer‐grained particles such as silt and clay. Most of the sediment in a stream is carried as […]
What is the importance of a control group?
What is the importance of a control group? The control group (sometimes called a comparison group) is used in an experiment as a way to ensure that your experiment actually works. It’s a way to make sure that the treatment you are giving is causing the experimental results, and not something outside the experiment. How […]
Which type of reaction occurs in the core of a nuclear?
Which type of reaction occurs in the core of a nuclear? Nuclear reactors are the heart of a nuclear power plant. They contain and control nuclear chain reactions that produce heat through a physical process called fission. That heat is used to make steam that spins a turbine to create electricity. Why is it important […]
In which states can convection occur?
In which states can convection occur? Convection is the transfer of heat energy through the movement of fluid particles. Hence, convection cannot take place in solids, since the solid particles are not fluid. Thus, convection only takes place in liquids and gases. Where can you see convection in everyday life? 13 Examples Of Convection In […]
