<span>The abundance and variety of fossils in Phanerozoic rocks have allowed geologists to decipher in considerable detail the past 600 million years or so of the Earth’s history. In Precambrian rocks, however, fossils are rare; thus, the geologic record of this important part of the Earth’s history has been especially difficult to decipher. Nonetheless, stratigraphy and radiometric dating of Precambrian rocks have clearly demonstrated that the history of the Earth extends billions of years into the past.</span>
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.
Since the air is a great thermal isolator, the windows prevent heat exchange better than one made out of a single thick sheet of glass. The air between the thin blankets is not moving around and will form an isolating layer that acts exactly like another blanket, thus improving the thermal isolation
The answer is B because prometaphase is the start of everything hence the "pro" at the beginning of the word
