It is 200 million years because it has been around for a long time.
In areas where the walls are frequently washed, conduit should be mounted with a 1/4 inch air space between the wall and the conduit.
Conduits are the structures that are hollow and cylindrical like a pipe, channel or tube through which any material can pass. The material can be electrical wires, gases or even water. Therefore, the functions of conduits is to mediate the transport of materials from one place to another.
These conduits can be rigid or flexible depending upon their use and the material to be transported. Care should be taken when these conduits are embedded inside the wall that they are not very close and in contact with the wall otherwise the conduits may get damaged.

Answer: The correct answer to the question is option 1
I SHOULD CALL THE CLINIC IF MY EYE BEGINS TO HURT.
Explanation: Cataract is the opasity or clouding of the lens of the eye making it to deviate from it's normal natural transparent/clear form.It is characterised by blurry vision.Treatment of cataract is by removal of the opaque cataract and replacing it with an clear artificial lens.
Cataract extraction and intraocular lens implant is a generally safe procedure,so when pain occurs after the procedure,it indicates that infection has set in or there is bleeding in the procedure site and it is advices that when a patient notices any of these,it should be reported immediately. Certain things should be avoided after cataract extraction and intraocular lens implant, things like soap,having a bath,washing the hair can all irritate the eye so all these should be avoided from few days to atleast 2weeks after the surgery.
When the patient that has undergone cataract extraction and intraocular lens implant experiences flashes of light,it indicates they there is retinal detachment,this is not expected, but if it is experienced by the patient,it should be reported immediately too.
As mentioned earlier, cataract extraction and intraocular lens implant is generally a safe procedure and rapid improvement in vision is always recorded in some people although some other patients stay several weeks before they achieve an improvement in visual acuity.
False negative is a condition when you got a negative result for a specimen which was positive. To prevent false negative occur, first you need to use golden standard test or a test with high specificity. You can do multiple tests to ensure the specimen is negative and using a positive control to make sure the reagent is still working fine.
