Which of the following best describes a difference between artificial and natural selection? The following statement best describes the difference between artificial and natural selection: Natural selection acts without the input of humans: artificial selection requires human input. only via natural selection, genetic drift, migration, or mutation. Which best describes the role of mutations in […]
Does all water run through water heater?
Does all water run through water heater? The cold water service line slopes away from the water heater after splitting from the main line. Instead of sending water through the heater, cold water service lines run directly to every water appliance in the home. To get to every appliance, these pipes need to run throughout […]

Which of the following noble gas is least Polarisable?
Which of the following noble gas is least Polarisable? Helium Why is argon a stable element? Nearly all of the argon in the Earth’s atmosphere is radiogenic argon-40, derived from the decay of potassium-40 in the Earth’s crust. The complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding […]
Why is momentum not always conserved?
Why is momentum not always conserved? The total momentum of both objects does not change. For this reason we say that the total momentum of the interacting objects is conserved. Newton’s third law implies that the total momentum of a system of interacting objects not acted on by outside forces is conserved. Is angular momentum […]
What does G pair with in DNA?
Are cathodes positive?
Are cathodes positive? The anode is the electrode where electricity moves into. The cathode is the electrode where electricity is given out or flows out of. The anode is usually the positive side. A cathode is a negative side. Is cathode positive or negative in battery? The electrode of a battery that releases electrons during […]
Are high luminosity stars rare?
Are high luminosity stars rare? The volume of space included within a distance of 5000 light-years, however, is enormous; so even though highly luminous stars are intrinsically rare, many of them are readily visible to our unaided eye. Does Chemo age your face? The study authors said a wide-ranging review of scientific evidence found that: […]
What does a circle around a weather station mean?
What does a circle around a weather station mean? A small circle is plotted on the map at the location where the weather measurements were made. The circle can be filled in to indicate the amount of cloud cover. Positions are reserved above and below the center circle for special symbols that represent different types […]
Are fault lines dangerous?
Are fault lines dangerous? Major active faults such as the Hayward Fault are associated with many hazards. The most obvious hazard is that of large earthquakes, which induce ground shaking over a large area that can cause heavy objects to fall and windows to shatter, and can cause structural damage to buildings and bridges. How […]
