I could be wrong but I think it's c.
Answer:
A
Explanation:
This is a double membrane organelle of 0.5- 1 to 1 micrometer in diameter; and 7 micrometre in length.
Since the resolution of light ,microscope is less than 200nm; only the mitochondrion can be seen with this microscope.
The mitochondrial functions a s the power house of the cell. for generation of ATPs
Howevrer the parts of other options are closer than 200nm in diameter and are ; therefore are not visible to this microscope.
Answer:
Endocrine disruptors are the synthetic or natural chemicals that may interfere with the functioning of the endocrine system in the human body. These chemicals mimic the naturally occurring hormones produced in the body like estrogen (a female sex hormone) and androgen (a male sex hormone) also these interfere with the production of the thyroid hormone. They bind to the receptors present in a cell and prevents the endogenous hormone from binding. The normal signaling process fails to respond properly.
Chemicals that functions as endocrine disruptors include dioxine, polychlorinated biphenyls (PCBs), pesticides and DDT.
The nurse should administer an injection of postexposure prophylaxis for tetanus. Tetanus is a toxic substance produced by a bacterium that cannot survive air (oxygen) exposure, that is why deep wounds are more vulnerable to tetanus. A moderate burn injury is considered an open dirty wound, therefore the patient should be protected from tetanus.
There is a vaccine for tetanus, that provides immunization from this disease, but it needs to be repeated every 10 years. However, in cases where there is an open dirty wound, the vaccine is believed to be inactive if it was not done within the last 5 years.
In this case, the child will not receive the tetanus vaccine, but an injection of active immunization, which acts much faster, but does not last as long as the vaccine.
