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.

How does the film industry help the local, state, national, and international economy?
AleksandrR [38]

Answer:

On Sunday, March 4th, the Academy of Motion Picture Arts and Sciences will host the 90th Academy Awards ceremony.

In addition to the event’s glamour and celebrity, the Academy Award season is an opportune time to consider something else about the film/video industry—its value to the U.S. economy, and to a few states in particular.

According to the latest figures from the Arts and Cultural Production Satellite Account (ACPSA), which is produced jointly by the U.S. Bureau of Economic Analysis and the National Endowment for the Arts, the film and video industry contributed $100 billion to U.S. GDP in 2015, and it employed 390,000 workers. Although the U.S. consistently runs trade deficits, movies/TV shows generate trade surpluses—$11.9 billion in 2015. The full figures for all ACPSA industries will be released this Tuesday, March 6th.

The 2015 figures also reveal a number of interesting facts about the film and video industry (i.e., business establishments that produce and distribute movies and TV shows; movie theaters, cinemas, and film festivals; and companies that provide post-production services such as film restoration):

1) The industry is huge. Film/video production is the third-largest of all ACPSA industries—in 2015, it accounted for 13 percent of all value added by U.S. arts and culture to GDP, ranking just behind arts-related broadcasting and government-produced arts and cultural commodities. The film industry places fourth in ACPSA employment, following arts-related broadcasting, government arts/culture, and the arts retail trade industry.

2) Film/video production is concentrated in California and New York, but also in Louisiana—the only state that approaches the other two by this measure.

The March 2018 release of the ACPSA is the first to include “value-added” figures by industry for each state and the District of Columbia. In California, the film and video industry contributed $49.1 billion to the state’s economy in 2015; in New York, it contributed $28.2 billion.

Value added to Louisiana by the state’s film/video industry was $2.7 billion. At first glance, the figure appears relatively small. As a share of the state’s overall economy, however, it is twice the national average.

Only California and New York show film and video production occupying a larger share of gross state product: in each state, the industry’s value-added is 3.5 times greater than the national index.

3) Six states have witnessed double-digit growth in film and video production. Between 2012 and 2015, value added (unadjusted for inflation) by the film and video industry grew by more than 11 percent in six states: South Carolina (20.1 percent); Connecticut (16.2 percent); Georgia (15.3 percent); Mississippi (13.6 percent); Rhode Island (12.7 percent); and Louisiana (11.7 percent).

4) The U.S. regularly generates a trade surplus in movies and TV shows. This trade surplus, which reached $11.9 billion in 2015, has doubled since 1998. Leading importers of U.S. movies and TV shows are the U.K, Germany, and Canada. In 2015, those three countries, combined, imported nearly $6.9 billion, or 39 percent of all U.S. movie/TV show exports.

5) Growth of the web-streaming industry is far outpacing that of the film/video industry. Between 2012 and 2015, average annual growth in real value added by the traditional film/video industry was just 0.2 percent, well below the 2.6 percent growth rate in real value added by all ACPSA industries.

A clue to this slow growth may lie in “other information services,” an industry that consists mainly of web-streaming, web-publishing, and similar services.

Over the three-year period, real value added by other information services grew by an average annual rate of 21 percent—the strongest growth rate, by far, of all ACPSA industries. The popularity of web-streaming services for TV and movies (both in the production and consumption of content) may be eroding the industry’s contribution to GDP.

The traditional broadcasting industry, like film companies, also produces movies and TV shows. In 2015, the film and video industry produced $79.5 billion in gross output of movies and TV programs. The broadcasting industry produced $429 million.

Of the ACPSA’s 35 industries, broadcasting (inclusive of TV and cable networks) generates the greatest value-added. In 2015, broadcasters (excluding sports broadcasts), added $127.8 billion to the U.S. economy. Between 2012 and 2015, average annual growth in arts-related value added by the industry was 2.6 percent, a rate on par with that of total arts and cultural value-added.

Im not 100% sure if this will help but hope it does!
