What increases effective population size? One of the things that can influence the effective population size is the sex ratio of the breeding animals. We can estimate Ne using information from a population census or pedigree database about the numbers of males (Nm) and females (Nf) that produce offspring in a generation. How does population […]
Why does the sky turn pink at sunset?
How many circles do you need to balance the scale?
Is milk a Newtonian fluid?
Is milk a Newtonian fluid? Newtonian fluids are those having a constant viscosity dependent on temperature but independent of the applied shear rate. Low-concentration liquids in general, such as whole milk and skim milk, may for practical purposes be characterized as Newtonian fluids. Is honey a non Newtonian? Honey is an example of a non-Newtonian […]
What is the oxidation number for CO in LiCoO2?
What is the oxidation number for CO in LiCoO2? +3 Which region of the periodic table shown here contains elements that are easiest to oxidize? b) Region D contains the least readily oxidized elements. Those elements lack one or two electrons to reach the electronic configuration of noble gases, so they want to accept new […]
What does high or low specific heat capacity mean?
What does high or low specific heat capacity mean? A substance with a high specific heat capacity can absorb a large quantity of heat before it will raise in temperature (water has a high specific heat). A substance with a low specific heat requires relatively little heat to raise its temperature (copper has a low […]
How long does a nuclear fuel rod last?
How long does a nuclear fuel rod last? To make that nuclear reaction that makes that heat, those uranium pellets are the fuel. And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that […]
What are some safety measures during severe bad weather changes?
What are some safety measures during severe bad weather changes? Stay indoors and move to a shelter – either an internal, ground-floor room with no windows or an official shelter nearby. Board up windows if you know about severe weather far enough in advance. Avoid metal, electrical, and tall objects during a thunderstorm. Never drive […]
What products increase friction?
What products increase friction? There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction […]
What best compares radiation and conduction?
What best compares radiation and conduction? The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves. What describes how radiation moves? […]
