Gravity
Plant roots always grow downward because specialized cells in root caps detect and respond to gravity. This is an example of a tropism. A tropism is a turning toward or away from a stimulus in the environment. Growing toward gravity is called geotropism.

B.The height of the lentil seedling would be an independent variable and the time passed would be the dependent variable.
C.The time passed would be an independent variable and the height of the lentil seedling would be the dependent variable.
The diagram below shows a cell undergoing mitosis (cell division). The correct order of the stages is B, C, D and A.
Mitosis is a type of cell division in which a parental cell divides to produce two genetically identical daughter cells.
In this case, an animal cell is undergone mitosis because the cell exhibits centrioles (only found in animal cells) and lacks cell walls (only present in plant cells).
The stages of mitosis include prophase, prometaphase, metaphase, anaphase, and telophase.
