B. oceans
C. rivers
D. deserts
Rivers are the geographic feature that gave rise to early civilization. The earliest urban foundations were made someplace in the scope of 4000 and 3000 B.C.E. when the rising of agribusiness and trade allowed people to have surplus food and financial security.
Since many people no longer needed to farm for food, a wide range of occupations and interests could flourish in a small area. Mesopotamia, Egypt, the Indus Valley, and China are the four oldest civilizations because they provided the foundation for ongoing cultural development.

A) a defect in the synthesis of the glucose-6-phosphate dehydrogenase
B) a defect in the mannose-6-phosphate receptor in the Golgi apparatus
C) a defect in the releasing small molecules from digested materials into the cytosol
D) a defect in a hydrolytic enzyme that breaks down polysaccharide
E) a defect in the process of adding a mannose-6-phosphate signal to lysosomal hydrolases
F) a defect in the mannose-6-phosphate receptor in the mitochondria
Answer:
B); D) and E)
Explanation:
B) a defect in the mannose-6-phosphate receptor in the Golgi apparatus.
Explanation: The mannose-6-phosphate receptors (MPR's) in the Golgi apparatus are essential for targeting the mannose-6-phosphate tagged lysosomal proteins to the lysosome.
D) a defect in a hydrolytic enzyme that breaks down polysaccharide.
Explanation: Lysosomes contain enzymes that hydrolyze polysaccharides, therefore any defects in these enzymes causes malfunctioning of the lysosome.
E) a defect in the process of adding a mannose-6-phosphate signal to lysosomal hydrolases.
Explanation: In the Golgi apparatus lysosomal proteins are tagged with mannose-6-phosphate so that they are specifically transported to the lysosomes.
