Insects has repeated modular segment that develop independently of each other promoted their diversification and evolutionary success. They are able to evolve appendage that are specialized for diverse functions.
Hypotheses propose that insect diversity either result form low extinction rates and resilience to mass extinctions and acquisition of key innovation that allowed them to radiate into newly formed niches.
There exoskeleton characteristics are commonly responsible for the diversification of insects on land. These insects are the amazing diversity in the surrounding , it believed that insects are so successful because they have protective shell /exoskeleton , they have small in size and they can fly.

Answer:
C) parfocal.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
A microscope is said to be parfocal if its lense is binocular and they can both be in focus.
Hence, if the objective lenses of a microscope can be changed without losing focus on the specimen, they are said to be parfocal.
Answer:
Opossums eat at night and eat mostly plants.
Explanation:
Striated skeletal muscle fiber
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.
