A compound isalways heterogeneouswhile a mixture may be heterogeneous or homogeneous. Can elements and compounds be heterogeneous? A heterogeneous mixture is a mixture of twoor morechemical substances (elements or compounds), where the different components can be visually distinguished and easily separat...
Let's start with the science.Spicy isn't actually a taste like salty ,sweet,sour and bitter—it 's a sensation.This sensation is triggered by a chemical compound(化合物) found in chilli peppers called 'capsiacin(残骸素).When we eat foods containing capsaicin,our bodies are tr...
The notion of broad-scale plant hormone analysis is hampered by the problematic selection of which hormone metabolites should be included in the analysis as some prior knowledge is required. Good candidates are compounds unique to the pathway of interest that play a significant role or which are ...
