What are the three levels of the federal court system? The federal court system has three main levels: district courts (the trial court), circuit courts which are the first level of appeal, and the Supreme Court of the United States, the final level of appeal in the federal system. What are two examples of cases […]
Why is hydrogen so special?
Why is hydrogen so special? Hydrogen is a colorless gas that is so much lighter than air that it can actually escape the gravitational pull of the earth and shoot off into space. Hydrogen is also the first element on the periodic table and has only on proton and one electron. Hydrogen does not have […]

Does voltage stay the same in series?
Does voltage stay the same in series? 2. In a series circuit the current is the same at any particular point on the circuit. 3. The voltage in a series circuit, however, does not remain constant. Why does voltage decrease in a series circuit? In series circuits, the resistor with the greatest resistance has the […]
What is the fifth state of matter?
What is the fifth state of matter? There are four states of matter common in everyday life — gases, liquids, solids, and plasmas. However, there is also a fifth state of matter — Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago. Is plasma The Fifth Element? Science is also getting […]
Why can hydrogen only have two valence electrons?
Why can hydrogen only have two valence electrons? Because hydrogen only has one electron surrounding its nucleus, its valence shell is the first energy shell, which only needs two electrons to be full. Hydrogen tends to form covalent bonds because a single covalent bond will fill its shell. How many valence electrons are present in […]
How do you appreciate the role of specific heat in our day to day life?
What if we could see gamma rays?
What if we could see gamma rays? If you could see gamma-rays, the night sky would look strange and unfamiliar. The gamma-ray moon just looks like a round blob – lunar features are not visible. In high-energy gamma rays, the Moon is actually brighter than the quiet Sun. Can gamma rays turn you into the […]
How long does overuse injury take to heal?
How long does overuse injury take to heal? Average healing time: Although the condition often gets better on its own, this injury can take between 3 – 12 months to fully heal. During this time, rest is extremely important in allowing the tendons and muscles heal. Targeted rehabilitation and stretches are critical for this process. […]
What happens when tryptophan is present?
What happens when tryptophan is present? When tryptophan is present in the cell, two tryptophan molecules bind to the trp repressor, which changes shape to bind to the trp operator. Binding of the tryptophan–repressor complex at the operator physically prevents the RNA polymerase from binding and transcribing the downstream genes. What time should I take […]
