Why does an apple look green?
Why does an apple look green? Green apples appear green because of chlorophyll in the peel. In red apples, the colour of chlorophyll is masked by the presence of anthocyanins, which are red in colour. Interestingly, anthocyanins accumulate in vacuoles, while the chlorophylls are present in chloroplasts of apple peel cells. Why is the color […]

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 […]
