What will happen if a house do not have a vent system? It can make our homes “sick”, with condensation and mould damaging the walls and fabric of our houses. But, more importantly, it can make the occupants sick. High humidity levels can affect allergies and complicate respiratory diseases brought on by certain biological agents […]
What increases effective population size?
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 […]

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.
