While developing countries may suffer from famine and starvation, the us and other developed countries create promote eating energy-dense foods and discourage regular physical activity. a) orexigenic environments
b) obesogenic environments
c) anorexigenic environments
d) lipogenic environments

The correct answer is option b) "obesogenic environments".

Explanation:

According to the article of Lake A "Obesogenic environments: exploring the built and food environments" (2006), an obesogenic environment is defined as "'the sum of influences that the surroundings, opportunities, or conditions of life have on promoting obesity in individuals or populations". This kind of environment is presented in the US and other developed countries, which contrast with the environment in developing countries who may suffer from famine and starvation.

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
