I cannot found the exercise anywhere, so I will just explain how the toxin works.
A toxin is a toxic substance made by a living organism such as a bacterium, a fungus, a plant or an animal.
Labil toxins are toxins which are by easily degraded. among these toxins, there is the toxin of Escherichia coli and the cholera toxin of <span>Vibrio cholerea.

The intracellular target of cholera toxin is adenylate cyclase, one of the most important eukaryotic cell regulatory systems. This enzyme is involved in the conversion of ATP into a cyclic AMP (cAMP), a crucial intracellular messenger in a wide variety of cellular processes.
Cholera toxin catalyzes the transfer of ADP-ribose from NAD (Nicotinamide Adenine Dinucleotide) to a specific arginine residue of the Gsa protein, resulting in the activation of adenylate cyclase and consequently the increase of the intracellular level cAMP. AMPc activates a cAMP-dependent protein kinase, which leads to phosphorylation of the protein, modification of ion transport and finally diarrhea.
The statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope is as follows:
- Compound light microscopes have higher magnification.
Thus, the correct option for this question is C.
<h3>What is a Microscope?</h3>
A microscope may be defined as a type of laboratory instrument that is significantly utilized to examine or observe objects that are too small to be visualized by the unaided eye.
Dissecting microscopes possess a lower magnification power as compared to compound light microscopes. Due to this, dissecting microscopes are used to visualize larger objects like tissues. Compound light microscopes use more than one glass lens. These types of microscopes are used to examine living cells.
Therefore, a compound light microscope has higher magnification is a statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope. Thus, the correct option for this question is C.

Answer: I should continue the exercise of upper arm as soon as I reach home.
Mastectomy is the removal of breast due to cancer or for the prevention of cancer. After this surgery there is a placement of plastic tube in order to collect the fluid so as to prevent infections. In this case just after the surgery the person should be engaged in exercises.
The person should not take part in any of the upper body movement as exercises, lifting heavy weights and any other activity which stresses the upper arm.
As long as the person is continuing the dressing she should not engage himself in any exercise.
