From the options given above, the two structures that will provide positive identification of a plant cell under a microscope are CHLOROPLAST AND LARGE CENTRAL VACUOLES.
Plant cells have some cell organelles which is unique to them, these organelles are not found in animal cells. Examples of such organelles are chloroplasts, large central vacuole, cell wall, etc. The chloroplast found in plant cells help the plants to trap energy from the sun during the process of photosynthesis. The large central vacuole found in plants play a critical role in turgor pressure of plants.
The equipment that the arson investigator used is ultraviolet
fluorescence. The mechanism in this Ultraviolet Fluorescence in which UV
radiation excites chemicals in object and causes them to release visible light.

Answer:
Anaerobes
Explanation:
Those organisms who live and reproduce in the absence of oxygen are termed as anaerobes. Those anaerobes that can not manage the presence of oxygen and harmed by even small quantity of oxygen are called obligate anaerobe, for example, <em>Clostridium botulinum</em>.
Those organisms which have the ability to grow in the absence of oxygen but utilize oxygen when oxygen is present are called facultative anaerobes for example in human intestine <em>E.coli </em>and other bacteria of Enterobacteriaceae family are facultative anaerobe.
There is one other category that contains anaerobe and called aerotolerant organisms which grow in the absence of oxygen and are tolerant towards oxygen. Therefore the correct answer is anaerobes.
<span>Producers or autotrophs
Autotrophs obtain energy by the process of photosynthesis. Any living organism need energy to survive and autotrophs are no different. Two types of autotrophs are present and they are Photoautotrophs and Chemoautotrophs. The Photoautotrophs rely on the energy produced during the process of photosynthesis and the Chemoautotrophs get their energy from most of the inorganic substances. Phtoautotrophs actually get their energy from the sunlight and then convert it into reusable form. In case of Chemoautotrophs ammonia is an important source of energy for them.</span>
