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.

Answer:
b. 10,000 plants
Explanation:
Producers, plants, contain the most stored energy in an energy pyramid.
I hope this helped :)
By using both of these schemes, energy source and locomotion, amoeboids can be classified properly. Both schemes play an important part of amoeboid’s taxonomy classification because these organisms changes its shape when feeding. Amoebas are traditionally classified under sub-phylum Sarcodina, single-celled with pseudopods (use for locomotion) but recent studies show that they are not monophyletic and actually belong to other groups of organisms — with locomotion and source of nutrients as basis.
B: Antigens
Explanation: Antigens itself are the invaders that causes an infection or a disease in living organism. They do not protect against invaders in non-specific response as they themselves are the ones who are invading the body.
Digestive enzymes are the enzymes that act on a particular substrate for its action at a particular PH.
Stomach acid is the hydrochloric acid that keeps the PH of the stomach low and prevents the growth of unwanted pathogens.
Lysosomes have digestive enzymes in it. It performs the process of phagocytosis.
