7 0

Answer:

Natural selection and selective breeding can both cause variations in animals and plants.

Cerrena [4.2K]

Answer:

That the material can be mixed with the original tissue

Explanation:

The biomaterial has the idea to be mixed with the original tissue, due is going to grow (if it is based in cells) or is going to attach to the biological tissue, so the H&E method can be confused. The hematoxylin is going to stain the nuclei of the cells meanwhile the eosin is going to stain the extracellular matrix and cytoplasm, so, if the biomaterial is mixed in the original tissue, can be confused the exactly boundary among the biomaterial and the biological tissue.

Hope this info is useful.

Cell wall - Adds structural support to the cell. Holds the cells together
Cell membrane - Serves as a barrier to the cell and allows more nutrient and molecules to move in and out of the cell without letting things that can harm the cell in. 
Outer membrane - Serves the same basic functions a the cell membrane. (Depending on how complicated the class your in is, I would visit this website for more information... https://en.wikipedia.org/wiki/Bacterial_outer_membrane )
Pili - Help the cell move and attach the bacteria to surfaces are other cells. 
DNA - Contains the genetic instructions on what the cell can physically do, operate, and reproduce. 
Flagellum - Helps the cell move. It kind of acts like a propeller for the cell so that it can move around.

Which is more important in the prophase of mitosis, that the chromatid pairs become visible, or the nuclear membrane disappears?
balandron [24]
  that the chromatid pairs become visible
<span>
Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>
