What happens when stomata are open? When stomata are open, water vapor and other gases, such as oxygen, are released into the atmosphere through them. A number of factors can affect the exchange of gases between a leaf and the atmosphere. What allows stomata to open and close? Specialized cells known as guard cells surround […]
How do chefs use chemistry?
How do chefs use chemistry? Any cooking you do involves chemistry. The use of heat, cold, and cutting changes the composition of foods. Even simply slicing an apple sets off chemical reactions that change the color of the apple’s flesh. If you heat up sugar to turn it into syrup, you’re using a chemical reaction. […]

At which type of boundary does tension often occur?
At which type of boundary does tension often occur? Divergent boundaries What’s the difference between convergence and divergence? Convergence generally means coming together, while divergence generally means moving apart. In the world of finance and trading, convergence and divergence are terms used to describe the directional relationship of two trends, prices, or indicators. What is […]
Is human eye better than camera?
Is human eye better than camera? Most current digital cameras have 5-20 megapixels, which is often cited as falling far short of our own visual system. This is based on the fact that at 20/20 vision, the human eye is able to resolve the equivalent of a 52 megapixel camera (assuming a 60° angle of […]
What is the difference between structural and ball and stick model?
What is the difference between structural and ball and stick model? A molecular formula uses chemical symbols and subscripts to indicate the exact numbers of different atoms in a molecule or compound. A structural formula indicates the bonding arrangement of the atoms in the molecule. Ball-and-stick and space-filling models show the geometric arrangement of atoms […]
Why diffusion is slowest in solid and fastest in gas?
Why diffusion is slowest in solid and fastest in gas? Diffusion takes place with slowest rate in the case of solids. The rate of diffusion is almost negligible in solids. Since the particles of solid have lowest kinetic energy so they do not move. Hence, diffusion takes a long time in the case of solid. […]
What is a rich sound?
What is a rich sound? Generally I would define “rich” bass as having a fairly flat frequency curve, which means all the finer details across the bass frequencies aren’t obscured by a nasty peak(s). So rather than having what’s known as “one note bass”, you have a smooth and detailed sound in which you can […]
