Describe how the functions of proteins differ from the functions of carbohydrates ( 150 words)

Component molecules assemble in different ways to form the basic units of carbs and protein. In carbs, that basic unit is a saccharide, another word for sugar. Monosaccharides are single-unit sugars, the simplest carbs. These can link up with each other to form two-unit sugars -- also known as disaccharides -- or polysaccharides, which can be hundreds of units in length. In contrast, amino acids are the basic units of proteins. Approximately 20 types of amino acids act as your body's primary protein building blocks. They can assemble in very complex ways to form helices, pleated sheets, globules or even multi-unit protein structures.

While protein's primary role is structural, carbohydrates primarily serve as an energy source. In fact, glucose -- one of the simplest carbohydrates -- is your body's preferred energy currency. Whenever your body derives energy from protein because of a low supply in carbs, protein components must undergo a number of biochemical changes to be useful in energy production. Proteins serve above all as your body's building blocks. Every cell needs them for structure, but they also play important roles as molecule transporters, hormones, disease-fighting agents and enzymes Some carbs -- namely fiber -- are important for bowel health and waste elimination

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
