1. What is an isomer? How many possible isomers of hexane are there? What are the structural differences between these isomers?
UNO [17]
When two compounds have same molecular formula but different structural formula, they are said to be isomers of each other and this phenomenon is called as isomerism. 

Hexane has six isomers.

The isomers of hexane have a difference in their structure due to parent chain length (chain isomerism). They are also differentiated on the basis of straight chain as in n-hexane and branched chain as in remaining five. Structures along with names are shown below.

What is the development of lymphocytes compared to other formed elements?
Katyanochek1 [597]
Lymphocytes and the other formed elements are developed from pluripotent stem cells. The pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. Myeloid cells start and complete their development in red bone marrow and give rise to red blood cells, platelets, eosinophils, basophils, neutrophils, and monocytes. Lymphoid stem cells begin development in the red bone marrow, but some are completed in the lymphatic tissues, where they give rise to lymphocytes. The B cell lymphocytes begin and finish in the red bone marrow and the T cell lymphocytes begin in the red bone marrow, but they mature in the thymus.
