As of 2015, the world population is 7.244 billion and recent reports suggest humans have between 20,000 and 25,000 genes and at least 8% of these genes have multiple alleles. Based on the data you have collected using [http://scienceprimer. com/punnett-square-calculator], would you expect there to be individuals that have identical genotypes (outside of identical twins)? How about identical phenotypes, could there be someone in the world that is phenotypically identical to you? Please explain your answer.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
