Explanation:
the respiratory system aids in the supply of oxygen to the blood and the exit of carbon dioxide. when the heart takes in blood that is short of oxygen and full of carbon dioxide, the pulmonary arteries pumps the blood to the lungs, who then fill the low oxygen blood with oxygen and transport the carbon dioxide out of the lungs. this oxygen rich blood, which now has a rich amount of hemoglobin, is transported to the heart which is pumped or circulated it to the entire body.

Answer:
Field guides
Explanation:
Various species of plants and nimals exists some of which bears very similar resemblance but for some key differences which may be unknown to learners or observers. A field guide gives a description of plants and animals, stating key physical differences between similar plants and animals. This helps learners distinguish between the related organisms. Field guides are most useful when applied to habitats where a range of similar organisms have been spotted and the field guide is then taken to such habitat to physically identify each different plant or animal.
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring
