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.
Assonance is the sound device in which vowel sounds of nearby words are repeated. These are usually found in prose and poetry, with the purpose of setting the mood.
Ex. "Hear the mellow wedding bells" in the poem The Bells by Edgar Allan Poe. In this line, the mood was set by using vowel "e" as literary device.
the answer is: The neutral stimulus causes no response.
Without being paired by any situation, neutral stimulus would not mean anything to the subjects. Because of this , the subjects would normally just ignore the neutral stimulus every time they face it.
But, when the neutral stimulus is paired with a certain situation (such as ringing a bell before giving foods to dogs), the dogs will associate the neutral stimulus with the positive reinforcement. To the point where the neutral stimulus transformed into a conditioned stimulus, which make the dogs'mouth to start watering every time they hear the bell.
