Answer:
Many cellular processes use similar mechanisms to achieve different goals.
Explanation:
<em>Metabolic pathways are series of enzyme-catalyzed reactions. Enzymes interact to remove and add phosphate groups to molecules or to move protons across a membrane. The same as in cell signalling, where the receptor proteins interact with specific molecules and often remove or ad phosphate groups. The phosphorylation of receptor proteins is very close to the process steps in metabolic pathways but with a very different function. </em>
<em>In metabolism phosphorylation is a method of transferring energy, in cell signalling it transmits information.</em>
A sample is termed REPRESENTATIVE SAMPLE if it has similar characteristics to the population being studied.
The representativeness of a sample is the extent to which its characteristics accurately reflects the characteristics of the population being studied.

The human cell has the largest surface area to volume ratio is Sperm cell or spermatozoa and its ratio is 1.55
<u>Explanation:</u>
Spermatozoa is a uni-flagellar motile sperm cell that basically determines the sex of an offspring. It moves from the haploid male gamete,its contributes in 1/2 nuclear genetic information to diploid.
The surface area of sperm cell is measured by micro-metric method or electron mircographs using stereo-logical method. While the volume will be measured by stereology or radio label volume exclusion method. The volume and surface area inversely proportional to cell size.
