C both the physical properties of a substance and its identity change.

D

the appearance of a substance changes but its identity does not.

Answers

Answer 1

Answer:

Im not 100 percent sure but I think C because a chemical change occurs when the chemical has broken composure so I think its C.

Answer 2

A chemical change occurs when both the physical properties of a substance and its identity change. The correct option is C.

What are chemical changes?

A chemical change is a change when the identity of a substance changes, and it converts into a new substance with new characteristics and a new identity.

When iron comes in contact with oxygen, it changes into rust, and it is a chemical change. A chemical change is a transformation in which the substance's chemical composition is altered through atom rearrangement. Atomic alterations cause changes in the molecular structure.

Chemical properties are those property properties of a substance that does not depend on the quantity of that substance.

Therefore, the correct option is C. both the physical properties of a substance and its identity change.

Explanation:

The movement of materials from the plasma membrane, through endosomes, and then to lysosomes describes which type of pathway?.

Answers

Answer:

Below

Explanation:

The routes that lead inward from the cell surface to lysosomes start with the process of endocytosis, by which cells take up macromolecules, particulate substances, and, in specialized cases, even other cells. In this process, the material to be ingested is progressively enclosed by a small portion of the plasma membrane, which first invaginates and then pinches off to form an endocytic vesicle containing the ingested substance or particle. Two main types of endocytosis are distinguished on the basis of the size of the endocytic vesicles formed. One type is called phagocytosis (“cellular eating”), which involves the ingestion of large particles, such as microorganisms or dead cells via large vesicles called phagosomes (generally >250 nm in diameter). The other type is pinocytosis (“cellular drinking”), which involves the ingestion of fluid and solutes via small pinocytic vesicles (about 100 nm in diameter). Most eucaryotic cells are continually ingesting fluid and solutes by pinocytosis; large particles are most efficiently ingested by specialized phagocytic cells.
