<h2>Scientific Theory of Cells</h2>

The scientific theory of cells, also referred ‘Unified Cell Theory’ or ‘Unifying Principle of Biology‘ was proposed by scientists like Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.

Explanation:

The basic principles of this theory are:

  1. All living or biological organisms, unicellular or multicellular, are composed of one or more number of cells accordingly.
  2. Cells are the ‘basic unit of life’.
  3. Life begins from cells and new cells are reproduced from ‘pre-existing cells’.

An organism is unicellular if it has a single cell like the amoeba, paramecium etc. An organism is multicellular if it has multiple cells like birds, reptiles, human beings, etc. A single cell can be simple or complex but any living organism is essentially composed of at least a single cell.

Consider the following geometric solids a sphere with a ratio of surface area to volume equal to 0.08 M negative one a right cir
azamat

Options:

A. The rate of diffusion would be the same for the two models.

B. The rate of diffusion would be faster for the right cylinder.

C. The rate of diffusion would be slower for the right cylinder.

D. The rate of diffusion would be faster for the sphere.

Answers:

The rate of diffusion would be faster for the right cylinder. Thus, the correct option is B.

To begin with, we must comprehend how the ratio of surface area to volume affects the rate of diffusion.

When comparing the ratio of surface area to volume, a body with a larger surface area will have a higher rate of diffusion than a body with a smaller surface area. It can be expressed mathematically as:

V∝ R    (whereas v is the diffusion rate and r is the surface area to volume ratio)

The answer to the question's surface area to volume ratio for spheres is given 0.8m⁻1

For a right circular cylinder, the surface area to volume ratio is provided  is 2.1 M.

The right circular cylinder has a larger ratio, hence it is obvious that the right circular cylinder will have a higher rate of diffusion because the rate of diffusion is directly related to the surface area to volume ratio.

What does the scientific process accoplish?
eimsori [14]

Answer:

The scientific method involves deriving hypotheses from theories and then testing those hypotheses. If the results are consistent with the theory, then the theory is supported. If the results are not consistent, then the theory should be modified and new hypotheses will be generated.
