The heavy wear of the incisors and canines in the early archaic and neanderthal specimens indicates a predominantly predatory/hunting life style of the two species in that time period, and that they had predominantly diet based on meat, which made their incisors and canines wear out more than the other teeth.

In exocytosis, a cell expels molecules and other contents that are too large to pass through the cell membrane structure. This discharge is accompanied by the fusion of the vesicular membrane and the plasma membrane. This process is carried out in three ways that separately involve the molecular constituents like endosomes, lysosomes, exosomes, neurotransmitters, etc.
In endocytosis, the body cells ingest various molecules such as proteins, polar molecules, and other substances, through their hydrophobic plasma membrane. This process is carried out by many eukaryotic cells to ingest food particles by surrounding them, and in this case, the plasma membrane is extended outwards. The basic mechanism of both the processes of exocytosis and endocytosis, is more or less the same. Vesicles are the structures used for the transportation of molecules. They are also used for storage and transportation of food. Also, many bacteria and pathogens may enter the body by this process. These structures may have a completely different internal composition as compared to that of the body cells.
Answer:
c - the volume of solution changes due to movement of water.
Explanation:
Passive transport is the movement of a substance from an area of high concentration to a low concentration across a semi-permeable membrane, that occurs without the expenditure of energy.
Option A is true: substances will always move from an area of high concentration to a lower concentration. This creates what is called a concentration gradient (which forms when a physical area contains a range of concentrations of s particular substance (option D). This occurs until the concentration of a solution approaches an equilibrium, as indicated in option B.
However, the movement of substances does not affect the movement of or the volume of water, only the chemicals, ions etc. in the water.
