TEETH The rabbits that have long teethes can be easily consume the plants (their food) compared to the rabbits with short teethes The long teethes also help the rabbits during competition or even when fighting with predators.FUR: Equator environment tend to choose the rabbits that have brown color of fur because the color is quite similar to soil ,prevent them from predator. Individual that adapt well with environment will be selected and have high survival and reproductive rate. Individual with certain traits will have advantage to adapt well with it environment. Variation can be defined as different characteristics in traits that occur within individual of same species. NATURAL SELECTION It is a theory proposed by Charles Darwin.

Specific base pairing arrangement A-T : 2 hydrogen bonds C-G : 3 hydrogen bonds Nitrogen bases attach to the sugar portion of the side Strands run in opposite directions Structure of DNA Consists of two strands of nucleotides that form a twisted ladder (double helix) Sugar and phosphate alternate along the sides of the ladder (linked by strong covalent bonds) Pairs of nitrogen bases form the rungs of the ladder (linked by weak hydrogen bonds). Nitrogen Base (four types, adenine, guanine, thymine and cytosine)Īdenine and Guanine are purines (composed of two rings of nitrogen atoms) Thymine and Cytosine are pyrimidines (composed of one ring of nitrogen atoms) Mohamad Arif Bin Nasaruddin D20091035123 Nor'atikah Bt Abdul Razak D20091035138 Nur Hatikah Bt Mohamad D20091035115Ĭurriculum specification of biology form 5īuilding block of DNA Composed of nucleotides Nucleotides contain three parts: 1.
