The smallest structures that biologists consider being alive are _____.
The smallest structures that biologists consider being alive are CELLS.
A(n) _____, by definition, is composed of two or more types of tissues.
ORGAN
The process of chemically changing nutrients and incorporating the resulting molecules into the body’s tissues is called _____.
ASSIMILTION?
The process by which organisms release substances such as vitamins, hormones, and saliva is called _____.
SECRETION
Define ingestion.
(nutrition, food-getting) – In order to live, all living things must have a constant supply of food which is used for energy or as a source of raw materials for growth and repair.
The process by which waste products are eliminated from the cell by diffusion through the cell membrane is called _____.
EXCRETION
Define egestion.
During ingestion materials are often taken into a cell or an organism which cannot be digested. This material must be emitted from the cell (or organism)-a process as called egestion. Examples: “fiber”, “bulk”, “roughage”
The process by which cells chemically break down small food molecules and release chemical energy for the cell’s use is called _____.
RESPIRATION
