Where is the offsprings? what’s the question?
Answer:
If Red blood cell is placed in a hypotonic solution, the water moves into the cell. The cell swells and become turgid.
Explanation:
This is a type of osmosis. here plasma membrane of RBC works as semipermeable(only solute can move) osmotic membrane.
We all know that, osmosis is a process where liquid moves across semipermeable membrane from less concentration gradient to high concentration gradient.
There are three types of solution in respect of the concentration of cell's cytoplasm. These are
- Hypotionic (when the solution is dilute than the conc. of cytoplasm). In this condition water moves into the cell and the cell become turgid. this is known as deplasmolysis
- Hypertonic ( when the solution is concentrated than cytoplasm), In this condition water moves out from the cell and the cell become flaccid. This is known as plasmolysis.
- Isotonic (when both the conc. of cell and solution are same). No osmosis takes place.
Answer:
(a).concentrated lactic acid and that of NAD+.
(b).use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.
Explanation:
To understand this question and be able to solve this question efficiently we have to understand the concept of "respiration''. But, the short and the most simple answer to the question above can be found in the first statement of the question.
The electron transport chain include the cycle that occurs during glycolysis, fermentation and the transformation of NAD+ to form NADH and vice versa.
In the research, the dependent variable is the concentrated lactic acid and that of NAD+.
In order to increase the validity of the experiment, the Researcher can make use of the response of NAD+ and lactic acid in absence of vitamin treatment as the CONTROL.
Think it is c but I could be wrong have not taken bio in a while
