I believe the answer is: Stop
The message 'stop !!' is usually used in a distressful situation where it is necessary to grab the attention of people near you.
For most people, it is easy to get the attention because our voice tend to rise in volume when we say 'stop'. For those who use hand signal, the sign must be really obvious and easy to understand by other people near them.
When planning a trip and deciding to drive your car or take the train, gasoline is a cost relevant.
<h3>What is Gasoline?</h3>
Gasoline is one of the most refined products that leave the refinery.
Automotive Gasoline is derived from relatively light fractions (C4-C12) by combining the products of various refinery activities, including isomerization, reforming, cracking, and alkylation reactions.
If Gasoline were solely the result of straight run fractional distillation, its composition would differ greatly and it would be an inadequate fuel for internal combustion engines.
Because lead-based chemicals can no longer be added to most Gasoline, the octane number is primarily improved by increasing the relative proportion of aromatic compounds and isoparaffins. .
Gasoline contains nearly all types of hydrocarbons in the C4 to C12 range, but is dominated by aromatic compounds, with alkylbenzenes being the most numerous and naphthalene- and indane-based compounds being less abundant.

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.
As a country, it can be said that the United States are composed of two types of government in terms of their scope of influence: state and federal governments. State-level governance manages the citizens who are living in that state, especially in terms of the applicable laws, while federal-level governance manages citizens country-wide. Historically, federal governments have more influence than state governments.
The answer to the question is that these factors have influenced the federal government’s influence over time: (1) changes in how the U.S. Supreme Court and others have interpreted the U.S. Constitution, (2) changes in the power of the purse, (3) changes in what the people (i.e., citizens, interest groups, and political parties) want the federal government to do, (4) changes in the number, size, and resources of federal bureaucratic agencies, and (5) amendments to the U.S. Constitution.
