Cellular structures and lifestyles
are much diversified.
In spite of these differences, the same basic molecular mechanisms govern the
lives of both prokaryotes and eukaryotes,<span> the general classes of
proteins involved in signal transduction are conserved all over living cell. This is manifested through the
re-used of protein receptors, protein kinases,<span> phosphoprotein phosphates, and ion channel receptors.</span></span>
<span>New combinations of genes may be produced by </span>immigration, mutation and sexual reproduction. These new combinations are also called variations.
Lets consider the water drop as being part of the water in a lake. The water droplet evaporates and changes from a liquid state to a vapor state by gaining energy and travels up to the upper atmosphere. In the atmosphere the water droplet once again condenses in the clouds and is stored until it can be precipitated on to the land again in the form of rain or other forms of precipitation.
