Cork cambium is the protective tissue of a stem. What mechanism does it use to protect the stem? A. Deposits of water in the cork cambium act as a barrier and protect the stem from water loss, physical damage, and invasion of pathogens.
B. Deposits of minerals in the cork cambium act as a barrier and protect the stem from water loss, physical damage, and invasion of pathogens.
C. Deposits of oils or waxes in the cork cambium act as a barrier and protect the stem from water loss, physical damage, and invasion of pathogens.

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.
