Define the five systems. Be sure to include enough information to distinguish each system from the others

By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:

Explanation:

Circulatory system - concerns with the circulation of blood

Digestive system - breaking down of food particles

Skeletal system - composed of bone structures serving as our body's framework

Nervous system - composed of nerve cells that responds to different stimuli

Respiratory system - concerns of utilizing the entry of oxygen and the exhalation of carbon dioxide.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
