cell theory establishes which of the following conclusions about cells?
A) all cells have the same size and shape
B) all cells form by free-cell formation
C) all cells are produced by other living cells
D) all cells have a cell wall
Answers
Answer:
C) all cells are produced by other living cells
Explanation:
Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.
What is cell theory?Cell theory is a scientific theory given in nineteenth century and according to cell theory " cell is the structural and fundamental unit of life" and " every living cell is made up of pre existing cell".
The cells in multicellular organisms function differently from those in single-celled organism. A unicellular depends upon only one cell for all functions occurred in body. On the other hand a multicellular organism has cells specialized to perform several body functions that combinedly support the organism.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialized it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of levour is at the orgneele level on the other hand in multicellular the division of lavour at cellular, tissue, organs and organ system level.
Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,Cell theory establishes the conclusion that " all cells are produced by other living cells". According to cell theory all the living cells are generated from pre- existing cells. Thus, option C is correct.

Water conservation is an important issue for many reasons. One factor is that water conservation preserves and protects our natural resources. Conserving water means more water is available to serve additional water needs, as well as for wildlife and recreation.

Conserving water diminishes our need to find or build new water sources, leaving them in reserve for our possible later use. Preservation does result in
A) lower algae levels
B) reduction in industry standards
C) slowing the building of new housing
