Which statement about the structure of collagen is false? a. the modified prolines found in collagen are synthesized from proline post-translationally by an enzyme called prolyl hydroxylase. b. prolyl hydroxylase requires ascorbic acid (vitamin c) to maintain its activity. c. collagen include the nonstandard residue 3-hydroxylysine (hyl). d. the introduction of vitamin c containing limes to the diet of the british navy alleviated scurvy and led to the nickname "limey" for the british sailor. e. scurvy is a disease caused by vitamin c deficiency that results in weak collagen. f. collagen includes nonstandard residues like 4-hydroxyproline (hyp) and 3-hydroxyproline.

the incorrect option about collagen is D

Explanation: All the statements listed above are all correct but the option that is not related to collagen and it's properties is option D(The introduction of vitamin C containing limes to the diet of the British navy alleviated scurvy and led to the nickname "limey" for the British sailor.)

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
