Can you have blue eyes if one parent has brown? The only way to present blue eyes is to inherit two copies of the blue-eyed gene. However, brown-eyed parents can pass a recessive blue-eyed gene. Therefore, two brown-eyed partners can birth a blue-eyed baby. Brown eyes + blue eyes = 50% chance of blue eyes, […]

What is difference between seismograph and Richter Scale? A seismograph is what scientists use to actually measure the earthquake and the Richter scale is a way of putting the data into an understandable context. The Richter scale is a logarithmic scale which means the number on the scale measure factors of ten. What is seismologist? […]

Why did Gregor turn into a bug? Kafka choose the form of a bug for “The Metamorphosis” because of the perception that a bug is perceived as a mindless systematic creature, a metaphor for the way Gregor lives his life, and acts in society. This is brought to light through Gregor’s transformation into a bug. […]

What is the formula of depth? real depthapparent depth=hh′=tanθ′tanθ=n. For water, n is about 43, so that the apparent depth is about 34 of the real depth. How do I calculate the pressure at the bottom of my pool? Pressure is the weight of the fluid mg divided by the area A supporting it (the […]

Should high handicappers use Pro V1? For some golfers, the Pro V1 is too soft, has too much backspin and flies far too high for their taste. While that opinion has some validity, the benefits of playing with the Pro V1 outweigh or dispel many of those accusations. It is just a terrific ball for […]

What can a cell do to maintain homeostasis? The cell membrane assists in the maintenance of homeostasis by: Maintaining a fluid phospholipid structure. Regulating osmosis, which is the tendency for water molecules to move from where there is a higher concentration to where there is a lower one. What are two ways we maintain homeostasis? […]

Which of the following enzymes is absent in lysosome? Lysosomes aka ‘suicide bags of the cell’ are membrane bound organelles containing hydrolytic enzymes. In their absence the following might result: Cancer. Why might happens if some lysosomal enzymes are absent? Along with them lysosomes also digest or damage their own cells by their enzymes, which […]

Do magnets affect cell phone batteries? Battery: Most phone batteries are unaffected by household magnets. The presence of a very strong magnetic field can cause the battery to work slightly harder to supply the right voltage and thus wearing the battery out faster. However, even a strong horseshoe magnet would not be enough to drain […]

Can a plane outrun the sun? Yes – but only in theory. The Earth is roughly 40,000km in circumference at the equator, and completes one rotation every 24 hours. This means that the Sun effectively zooms across the face of the Earth at the equator at around 1,700km/h. So you’d have to travel at least […]

How do you end a filibuster? That year, the Senate adopted a rule to allow a two-thirds majority to end a filibuster, a procedure known as “cloture.” In 1975 the Senate reduced the number of votes required for cloture from two-thirds of senators voting to three-fifths of all senators duly chosen and sworn, or 60 […]
