a scientist plans to use a microtome to cut sections of a particular type of tissue so then that typical cell will be cut into about 20 sections. to help him make careful observation of internal cell structures, he considers staining the sections with a dye. which of the following procedures would give the most complete pictures of the internal stuctures of a cell?

1) look at one section
2) look at 20 sections from 20 different pieces of tissue
3) stain all the sections then look at 20 sections from 20 different pieces of tissue
4) look at 20 consecutive stained sections of a cell from the same piece of tissue
5) either b or c would be equally good procedures to ensure observation of the complete internal contents of a cell.

I think its 4

4) look at 20 consecutive stained sections of a cell from the same piece of tissue

This procedure would give the most complete pictures of the internal structures of a cell. By looking at 20 consecutive sections from the same piece of tissue, you would be able to observe the internal structures in a sequential manner. Staining the sections would enhance the visibility of the internal cell structures, allowing for a detailed examination. Looking at multiple sections from different pieces of tissue (option 2) or staining all sections and looking at 20 different sections (option 3) would provide a broader sample, but may not provide as comprehensive of a view of the internal structures compared to looking at consecutive sections from the same piece of tissue.

To determine the procedure that would give the most complete pictures of the internal structures of a cell, we need to consider the advantages and limitations of each option.

1) Looking at one section: This procedure would only provide information about the internal structures present in that specific section. It may not capture the complete picture of the cell's internal structures.

2) Looking at 20 sections from 20 different pieces of tissue: By examining multiple sections from different pieces of tissue, we can get information about the internal structures in each section. However, this method does not guarantee that we will observe all the internal structures present in a single cell, as different cells may vary in their internal structures.

3) Staining all the sections then looking at 20 sections from 20 different pieces of tissue: By staining all the sections, we enhance the visibility of the internal structures in each section. However, this method still suffers from the same limitation as option 2, as different cells may have varying internal structures.

4) Looking at 20 consecutive stained sections of a cell from the same piece of tissue: This procedure involves examining consecutive sections, meaning that any variations or changes in internal structures within the same cell can be observed. This method provides a more complete picture of the internal structures of a single cell.

5) Either option (b) or (c) would be equally good procedures to ensure observation of the complete internal contents of a cell: This option suggests that examining multiple sections from different pieces of tissue (b) or staining all the sections (c) would both be equally effective in capturing the complete internal contents of a cell. However, considering the specificity of the question, option (d) is a more suitable answer.

Therefore, option 4) "Look at 20 consecutive stained sections of a cell from the same piece of tissue" would give the most complete pictures of the internal structures of a cell.
