Organization and Development of Living Things Online Quiz

Cells must eliminate metabolic waste products to prevent toxic accumulation and maintain stable internal conditions. Shivering and sweating are organism-level responses, not cellular processes.

Cells require energy to perform all their functions, including maintaining homeostasis. Extracting energy from food (cellular respiration) is essential for survival.

Homeostasis is the biological process by which organisms maintain a stable, balanced internal environment despite external changes.

According to the cell theory, all living organisms are composed of one or more cells. This is the fundamental shared characteristic between a single-celled protist and a multicellular tigress.

The cell theory states that all living things are made of cells, cells are the basic unit of life, and all cells come from pre-existing cells.

Cell theory states that all cells arise from pre-existing cells through cell division. This principle, established by Rudolf Virchow in 1855, contradicts the earlier idea of spontaneous generation. Options A, B, and C are scientifically incorrect - cells do not come from kinesised (not a biological term), brain cells, or dead cells.

Cell theory defines the cell as the basic structural and functional unit of all living organisms.

Cell theory states that all living organisms are composed of one or more cells.

The biological hierarchy is: cell, tissue, organ, organ system, organism. Therefore, organ systems exist between organs and the whole organism.

The biological hierarchy is: cell, tissue, organ. Thus, tissues are the level between cells and organs.

The correct sequence is: tissues → organs → organ systems. Organs are positioned between tissues (groups of cells) and organ systems (groups of organs working together). Atoms are much smaller (chemical level), tissues are below organs, and organism is at the top of the hierarchy.

In the hierarchy of life, the organism is the most complex level, representing the complete individual living thing.

An organism is an individual living entity that can carry out all life processes independently.

An organ system is a group of organs that work together to perform complex body functions.

The cell is the smallest structural and functional unit of an organism that is capable of performing all life processes.

An organ is a structure composed of different types of tissues that work together to perform a specific function.

A tissue is a group of similar cells that work together to perform a specific task or function.
