The answer is a. minimizes the chance of accidents occurring in the lab.
Technically, the answer could be c, because the point of safety rules is to stop accidents from happening, but accidents can still occur EVEN when you are following the rules.
Answer:
E) scanning electron microscopy
Explanation:
A biologist who was studying kidney tubules in small mammals wants to specifically examine the juxtaposition of different types of cells in these structures. The cells in question can be distinguished by external shape, size, and 3-dimensional characteristics using a Scanning electron microscopy.
Scanning electron microscopy (SEM) is used to examine the ultrastructural morphology of the cells of the kidney tubules. The Material for study is isolated and fixed by vascular perfusion. SEM is a form of electron microscope that gives pictorial view of a sample using a focused beam of electrons to scan the sample to reveal the surface topography and constituents of the sample.
SEM can produce resolution that is more than 1 nanometer.
Specimens are viewed in high vacuum in conventional SEM, or in low vacuum or wet situations in different pressure or environmental SEM, and at a broad set of cryogenic or increased temperatures with specialized tools.
Advantages of a Scanning Electron Microscope are its broad-array of uses, the well structured three-dimensional and topographical imaging or pictorial representation plus the varying information assembled from seperate detectors.
Answer:
During El Niño events, the shift in rainfall away from the Western Pacific may mean that rainfall across Australia is reduced. Over the southern part of the continent, warmer than average temperatures can be recorded as weather systems are more mobile and fewer blocking areas of high pressure occur.
