The early hypothesis of was based on observations that suggested continents were once joined together. later, the theory of explained why large pieces of earth's surface move around and how many of earth's features form. a. continental drift; plate tectonics b. plate tectonics; continental drift c. gravitational force; continental drift d. plate tectonics; gravitational force

Continental drift; plate tectonics

Alfred Wegener develoepd the hypothsis of contenetial drift. This hypothesis basically implied that the continents were in motion. Scientists, though, were left to wonder why. In this case, the theory of plate tectonics explained Alfred Wegener's hypothesis of the continents moving.

lysosomes contain a variety of enzymes, enabling the cell to break down various biomolecules it engulfs, including peptides, nucleic acids, carbohydrates, and lipids (lysosomal lipase). the enzymes responsible for this hydrolysis require an acidic environment for optimal activity. hope i !
