Answer:
One.
Explanation:
SDS (sodium dodecyl sulfate) PAGE ( Polyacrylamide gel electrophoresis) is the technique of the separation of the molecules on the basis of their molecular weight.
The beta-mercaptoethanol reduces and break the disulfide bonds present in the protein. When the protein X with the beta-mercaptoethanol is allowed to run on the gel, only one band will visible all the subunits have equal weight and will present at the same location on the gel.
Thus, the answer is one.
Plant cell Animal cell
2. Have a cell membrane. 2. Have no chloroplasts.
3. Have cytoplasm. 3. Have only small vacuoles.
4. Have a nucleus. 4. Often irregular in shape.
5. Often have chloroplasts containing chlorophyll. 5. Do not contain plastids.
They both have a membrane and vacuole
Answer:
Option E.
In order for oxygen in the inspired air to reach hemoglobin, it must diffuse across all of the following structures, except: one or two smooth muscle cells.
Explanation:
- In the process of oxygen reaching hemoglobin it gets diffused across layer of surfactant, an endothelial cell, type I pneumocyte, and the plasma membrane of the erythrocyte.
- The molecule that is responsible for the carrying of oxygen into the blood cells is protein hemoglobin.
- The normal adult human's blood is the mixture of six different species of hemoglobin molecules. These all molecules consist of same function as well as structure.
Compared to benign tumors, malignant tumors are different because the cells in malignant tumors are cancerous.
