Earth has seasons because its axis is tilted.
A meteor is what is seen when a meteoroid enters Earth's atmosphere and becomes visibly bright.
Answer: The correct option is E ( Intermediate filaments are unpolarized).
Explanation:
Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.
Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments
The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments

Answer: Option B) All living organisms are composed of multiple cells.
Explanation:
According to the CELL THEORY
- the cell is the structural and functional unit of life
- all living organisms are made of cells
- all cells come from previously existing cells
- there is no life apart from the life of cells
- all living things are either single cells (unicellular) or group of cells (multicellular).
Thus, the correct statement is that all living organisms are composed of multiple cells
