<span>There is an organ in the brain sensitive to light changes, which then affects our sleepiness.
This sensitivity to light changes will determine our response to melatonin that influences our level of 'tiredness'.
The more melatonin that we have in our body, the more likely we feel sleepy and fall asleep.</span>
I pick textile as the answer
La geografía de un país tiene un gran impacto en su cultura. Si un país está muy aislado por la tierra o las masas de agua, puede ser difícil comerciar y / o interactuar con las culturas de otros países. Dependiendo de los recursos disponibles dentro del país, el aislamiento puede ser algo positivo o negativo. Un país cercano a otros países puede verse muy influenciado por el colonialismo o por ser una potencia colonial, y el comercio entre los dos países podría llevar a la interdependencia, o un poder dominante y sumiso.
English: How does the geography of a country affect its culture?
A country’s geography has a large affect on its culture. If a country is greatly isolated by land or water masses, it can be difficult to trade and/or interact with other countries cultures. Depending on the resources available within the country, isolation can be a positive or negative thing. A country in close proximity to other countries can be greatly influenced through colonialism, or by being a colonial power, and trade between the two countries could lead to interdependence, or a dominant and submissive power.
