Answer: A red blood cell will swell and undergo hemolysis (burst) when placed in a hypotonic solution. When placed in a hypertonic solution, a red blood cell will lose water and undergo crenation (shrivel).
The liquid should be neutralized.
In the stomach, the pH value is around 2.0, which is because of the hydrochloric acid in the stomach. It can provide a optimum pH for the stomach enzymes.
However in the small intestine, the enzymes there works in a optimum pH of around 8.0, therefore the liquid must be neutralized before going into the small intestine, or else the enzymes in the small intestine will be denatured due to extreme pH.
Neutralization can be done by the sodium hydrogen carbonate, which is a alkali produced in small intestine.
Example:
What is the difference between Telophase and Cytokinesis? Telophase is the final stage of nuclear division, whereas cytokinesis is the final stage of cell division. ... Telophase results in two daughter nuclei, while cytokinesis results in two separate daughter cells
I believe the answer to this question is D, I am not sure though.
Answer:
True.
Explanation:
Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.
