Does UV light break down ozone? UV light will create ozone from atmospheric oxygen at short wavelengths of less than 240 nanometers (nm). UV light will also destroy ozone and break ozone back down into atomic oxygen (O) and diatomic oxygen (O2) at wavelengths from about 200 nm to 315 nm. How do you kill […]

What is an example of screw? Some examples of the uses of a screw are in a jar lid, a drill, a bolt, a light bulb, faucets, bottle caps and ball point pens. Circular stairways are also a form of a screw. Another use of the screw is in a device known as a screw […]

What is the use of chloroplast in our daily life? The chloroplast absorbs the energy in sunlight and uses it to produce sugars. Chloroplasts play an important part in the process of photosynthesis in some organisms. The chloroplast absorbs the energy in sunlight and uses it to produce sugars. What is chloroplast in real-life? Chloroplasts: […]

How do I raise the pH in my pool without alkalinity? Use Aeration to Raise Pool pH (and not Alkalinity) You can’t, but you can raise pH without affecting Alkalinity. This is done by lowering the pH and Alkalinity with pH Decreaser, then raise the pH through aeration. Just add air! How do I fix […]

What are the 2 main functions of the skin barrier? The skin consists of two layers: the epidermis and the dermis. Beneath the dermis lies the hypodermis or subcutaneous fatty tissue. The skin has three main functions: protection, regulation and sensation. What ingredients repair skin barrier? Whether your skin’s barrier is damaged or healthy, it’s […]

What cartilages of the larynx play the most important in sound production? The arytenoid cartilages are roughly pyramidal masses of cartilage that sit on top of the posterior side of the cricoid cartilage. These tiny cartilages play a vital role in the production of sound and act as the pivot points for the vocal folds […]

What is the lowest passing grade? D Are BS a good grade? If you really are focused on bringing your grade up, consider asking for any extra credit you may be able to complete A B- is still a good grade, so don’t stress yourself. A grade of B will not keep you out of […]

What are the 5 types of gene mutations? What kinds of gene variants are possible? Missense. A missense variant is a type of substitution in which the nucleotide change results in the replacement of one protein building block (amino acid) with another in the protein made from the gene. Nonsense. Insertion. Deletion. Duplication. Frameshift. Repeat […]

What are 2 types of cellular respiration? There are two main types of cellular respiration—aerobic respiration and anaerobic respiration. Aerobic respiration is a specific type of cellular respiration, in which oxygen (O2) is required to create ATP. What is the fundamental difference between photosynthesis and cellular respiration? What is the relationship between photosynthesis and cellular […]

Is force dimensionless quantity? The ratio of the internal forces to the external forces will depend upon its speed, and the viscosity of the fluid, and the size of the body. But the ratio of the internal to the viscous forces is dimensionless, so it must depend on some combination of the viscosity, speed V […]
