two classes of angiosperms

Introduction - There have been several attempts to classify angiosperms, the flowering plants. One of the earliest attempts in this direction was that of Carolus Linnaeus. He attempted a classification of angiosperms based on the characteristics related to flowers. Subsequent ta..

Introduction - In the description of Angiosperms, family is the most useful taxonomic unit. Ranks higher than family are not of much practical significance and are used mostly in classification systems and academic discussions. The taxonomic category genus also does not get much importanc..

Let f:AgB and g:AgB be two functions. Thus the composition of two functions f and g denoted by gof or fog is the function from A into C defined by gof = {(a,b) for some c B, (a,c) f and (c,b) g}.Let f:AgB and g:AgB be two functions. Thus the composition of two..

The four electron pairs (two bond pairs + two lone pairs) are distributed tetrahedrally around the central atom as shown below. The two lone pairs on the central atom repel the bond pair slightly inwards due to greater lone pair-bond pair repulsion. As a result, the b..

A catalyst does not alter the equilibrium point. In a reversible reaction, a catalyst increases the rate of forward as well as backward reaction to equal extent. Therefore, the equilibrium point is not altered. However, the equilibrium may be attained faster in the presence of a catalyst..
