Answer:
The question to be asked an investigated when observing a structure under the microscope to determine whether it is living is if it has a nucleus if eukaryote or nucleoid if prokaryote.
Explanation:
The major organelle that must be present in all living cells is the nucleus or nucleoid and the protoplasm. The observation of the cell under the microscope will show the subcellular entity, nucleus/nucleoid, more pronounced than other organelles in the cell. The nucleus house the necessary information for the maintenance and reproduction, which is mainly the genetic information that dictates the translational protein products that are needed to build another aspect of the cells. Therefore, when such a tiny structure is placed under the light microscope under the view of oil immersion, the nucleus of the cell should be visible if it is a living structure.
Deuterostome would be my best guest since it pairs with another thing.
No more than five trophic levels are present in an ecosystem, most have only 4.
Answer:
Plastic and trash bags can be used to generate renewable energy in the following way the mechanism of cold plasma pyrolysis.
Explanation:
- Cold plasma pyrolysis is a method in which chemical compounds like plastic wastes and trash bags are subjected to high temperatures like 400 to 650 degree Celsius under limited oxygen condition.
- The above process generates huge amount of energy in the form of heat that can be converted to usable electricity.
- The process generates compounds like hydrogen, methane and ethylene.
- The hydrogen and methane can be used as clean fuels because they produce minimum harmful components like carbon dioxide and soot on combustion.
- The ethylene is the basic component of plastics and can be reused to produce more plastics.
