Explanation:
The correct answer is Perception
It is the process of selecting, organizing and interpreting stimuli (events, information, objects, other people). Interpretation is a decoding that lends value to the stimulus.
Different people react differently to the same stimulus. Thus perceived reality causes different perceptions as the observer changes.
Answer: The correct answer is : Plenum
Explanation: This space between the roof and the next level floor is generally one to three feet wide in order to allow ventilation systems that can economically collect the air returned from the offices on the floor. The plenum is a closed space where there is air and other gases at low speed and with a little higher pressure than the atmosphere.
Answer: The research team can conclude right away that the cell line is a "cancer cell or a cell that emanates from a tumor cell".
Explanation: 'Density-dependent inhibition is when cell growth has a reached a limited density which in turn will slow down the rate of cell growth because of lack of new 'anchorage' point (new cells to adhere and be in contact with).
'Anchorage Dependence' is the need for cells to be in contact (adherence) with another layer of cells. Cells require anchorage in order to survive.
The reason why the researchers will conclude right away that the cell line is a "cancer/tumour cell" is because normal cells display density dependence inhibition while cancer cells 'proliferate' (increase in number) regardless/independent of cell density.
Normal cells adhere to each other (need to be in contact with each other) and form orderly array of cells while cancer cells do not adhere to cells and can migrate over adjacent cells thereby growing in a disorderly manner.
