Why is deletion mutation harmful? Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered. What is the […]

What is enzyme and types? According to the International Union of Biochemists (I U B), enzymes are divided into six functional classes and are classified based on the type of reaction in which they are used to catalyze. The six kinds of enzymes are hydrolases, oxidoreductases, lyases, transferases, ligases and isomerases. How do you name […]

How do you know if an appliance is grounded? You can usually tell whether your electrical system is grounded by checking your power outlets. If they accept plugs with three prongs, your system should have three wires, one of which is a grounding wire. Similarly, an appliance designed to be grounded is equipped with a […]

Can humans grow tails? Many believe that human ancestors had and used some form of a tail. Over time as a species, however, we evolved past the need for such an organ, which is why the majority of humans no longer grow them. Most humans grow a tail in the womb, which disappears by eight […]

Is 10cc equal to 10 ml? 1ml is equal in volume measurement to 1 cc. equal to 1ml= 1 cc or cm3; So, 10 ml is close to 10 cm3 or 10cc. Is 1cc the same as 1 ml? What’s the difference between a cubic centimeter (cc) and milliliter (mL)? These are the same measurement; […]

Are most stars redshifted or Blueshifted? Are most stars redshifted or blueshifted? Most stars are affected by redshift. This tells us that the universe is expanding and the galaxies with high gravity that are close are blue shifted while the rest spread apart and are redshifted because of the expansion. Is redshift moving away or […]

Is flow rate the same as velocity? Rate of flow, or simply flow, is the quantity of water, for example, that flows in a tube or other medium, in an interval of time. Examples: 2 kg of water per second, or 100 cubric meters of air per minute. Velocity is how fast the water, air […]

What is the difference between polar and spherical coordinates? Spherical coordinates define the position of a point by three coordinates rho ( ), theta ( ) and phi ( ). is the distance from the origin (similar to in polar coordinates), is the same as the angle in polar coordinates and is the angle between […]

What does it mean when correlation is significant at the 0.01 level? Saying that p<0.01 therefore means that the confidence is >99%, so the 99% interval will (just) not include the tested value. They do not (necessarily) mean it is highly important. The significance level, also denoted as alpha or α, is the probability of […]

Does the 9th planet exist? The ninth planet was no more. At the same time, the discovery of these objects uncovered a major new lead in the search for a hidden planet. It turns out that Sedna is not moving in the way everyone expected – tracing elliptical rings around the Sun, from within the […]
