What parts of cells use up the most oxygen? mitochondria What happens if your cells don’t get enough oxygen? If blood oxygen levels are too low, your body may not work properly. Blood carries oxygen to the cells throughout your body to keep them healthy. Hypoxemia can cause mild problems such as headaches and shortness […]
How do inducible promoters work?
How do inducible promoters work? Promoters control the binding of RNA polymerase and transcription factors. Since the promoter region drives transcription of a target gene, it therefore determines the timing of gene expression and largely defines the amount of recombinant protein that will be produced. What is a CMV promoter? What is a CMV promoter? […]

What prevents sperm from reaching the egg?
What prevents sperm from reaching the egg? Cervical mucus may prevent sperm from passing into the uterus, but during ovulation when the egg is released from the ovaries, the mucus gets thinner and lower in pH. These changes make the mucus a great transport medium for the sperm, and help the sperm continue traveling. What […]
What is the focal length of a spherical mirror if the radius of curvature is 30 cm?
What is the main purpose of transformer?
What is the main purpose of transformer? 1) What is a transformer and how does it work? A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. Which part of transformer […]
What are the two major types of somatoform disorders?
What are the two major types of somatoform disorders? The two main types of somatoform disorders that produce psychogenic neurologic problems are conversion disorder and somatization disorder; the latter is also known as hysteria or as Briquet syndrome.

What is the trend of a line?
What is the trend of a line? A trendline is a line drawn over pivot highs or under pivot lows to show the prevailing direction of price. Trendlines are a visual representation of support and resistance in any time frame. They show direction and speed of price, and also describe patterns during periods of price […]
Can a magnetic field do work on a moving charged particle?
Can a magnetic field do work on a moving charged particle? The magnetic force does no work on a charged particle. Therefore a magnetic field cannot be used to increase the energy of a charged particle. If v and B are perpendicular the particle will move in a circular path. Why do magnetic fields only […]
Does electricity need a circuit?
Does electricity need a circuit? The flow of electricity depends on an energy source and a path, or circuit, through which it can travel. What are the 5 parts of an electrical circuit? The following common components are used in most printed circuit boards: Resistors. Resistors control the electric currents that pass through them, as […]
