Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, many debates about cells began amongst scientists. Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839. This is usually credited to Matthias Schleiden and Theodor Schwann. However, many other scientists like Rudolf Virchowcontributed to the theory. It was an important step in the movement away from spontaneous generation.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
The first of these tenets is disputed, as non-cellular entities such as viruses are sometimes considered life-forms.
All living things are made of cells. Answer
something that causes an organism to decay. It could have been eaten, or an air pocket formed as it was fossilizing or basically anything that obstructs the formation of a fossil.... you have to figure the rest out; )
This illustrates that the two animals (the horse and the lion) do not eat the same type of food. This could also show one way of classification between different animal species.
Answer: the increased surface area aids in the better absorption of drugs.
Explanation: According to Noyes- Whitney equation, increased absorption of drugs depends on the rate of dissolution which is modified by altering the surface area. Reduction of the drug size from solid to powder form increases the specific surface area and the dissolution rate. This unique quantity makes it a fast acting medication since it's absorbed faster.
