Answer:
The invention of the toothbrush made a huge impact of society and people for many reasons. You should always brush your teeth and keep your mouth clean so you will have nice, white teeth, healthy gums, good breath, and just a clean mouth! Without the toothbrush, your mouth would be smelly, gross, and full of bacteria.Some of the different impact categories included acidification, climate change, eutrophication, human health, land use, resource use and water scarcity. The results concluded that the electric toothbrush had the greatest environmental impact in 15 out of the 16 categories with water scarcity being the exception.Using the electric toothbrush as an example, this article examines the growing acceptability of domestic health technologies that blur the traditional boundaries between health, aesthetics and consumption. By using empirical material from individual and household interviews about people's oral health practices, this research explores the relationships between an everyday artefact, its users and their environments. It investigates the ways in which oral health technologies do, or do not, become domesticated in the home environment. We conclude that the domestication of oral health technologies is not inevitable, with the electric toothbrush often becoming an ‘unstable object' in the domestic setting.

Answer:
competitive
Explanation:
An inhibitor is a substance that hinders the action of an enzyme. An inhibitor may be competitive or non competitive.
A competitive inhibitor is an inhibitor that is very similar to the substrate hence it binds to the enzyme instead of the substrate. A noncompetitive inhibitor binds to a site that is different from the active site. This site is called an allosteric site.
If we look at the experiment described in the question, the reaction rate decreases upon addition of the inhibitor. This effect is reversed by adding a large quantity of substrate.
The implication of this observation is that the enzyme and the inhibitor compete for the active site on the substrate.
Hence the inhibitor is a competitive inhibitor.
Answer:
The first Industrial Revolution began in Great Britain in the mid-to-late 1700s, when innovation led to goods being produced in large quantities due to machine manufacturing.
This process began in Britain in the 18th century and from there spread to other parts of the world. Although used earlier by French writers, the term Industrial Revolution was first popularized by the English economic historian Arnold Toynbee (1852–83) to describe Britain's economic development from 1760 to 1840.
