Answer: Decreased levels of melatonin
Explanation: Melatonin is a substance that is excreted at night and by which the brain sends signals that one should sleep, that is, a man / woman is feeling sleepy. When melatonin secretion decreases, the alertness increases, as is the case with Colby. Melatonin levels decrease at the base of the brain signal regardless of whether or not Colby slept enough the previous night. Feeling tired will induce some other receptors and consequent signals from the brain, but a natural decrease in melatonin throughout the day occurs normally.

The Portuguese Burghers[1][2][3] are an ethnic group in Sri Lanka, of mixed Portuguese and Sri Lankan descent.[4] They are Roman Catholic and spoke the Sri Lanka Indo-Portuguese language, a creole based on Portuguese. In modern times, English has become the common language while Sinhalese is taught in school as a second language. Many Portuguese Burghers living on the east coast of Sri Lanka are of Portuguese descent; this is evident in the Sri Lanka-Indo Portuguese language, which has many affiliations to Sinhalese and Portuguese.[5] They are mixed with other Burgher people, including Dutch Burghers. However, Portuguese Burghers are not Dutch Burghers.[6]

Answer and explanation:
The Columbian exchange or Columbian interchange is a term named after Christopher Columbus. It refers to the colonization and subsequent trade that began with Columbus's trip in 1492. The Columbian exchange involved the Americas, Europe, and West Africa during the 15th and 16th centuries, and resulted in an extensive transfer that greatly impacted all involved. The term contemplates not only the trade of goods, but also of animals, people, cultures, and even diseases. Some of the major things exchanged were domesticated animals - horse, donkey, chicken, cattle, turkey, parrots, guinea pig, etc. -, and fruits and plants - acai, avocado, broccoli, celery, carrot, chia, pecan, oregano, etc. It's worth remembering that products were exported to and from both the New and the Old Word. A side effect of such contact between different continents and people was the transfer of diseases. Indigenous people in the Americas were decimated by the illnesses transmitted by colonizers. The exchange of cultures had a great impact on both Europe and North America. Enslaved Africans brought their knowledge concerning agrarian practices such as water control and milling. Europe began shifting towards Capitalism and was the subject of population growth due to the availability of new products and crops. Colonizers introduced European values to indigenous nations, ranging from land possession and division to monogamy. There was a noticeable disrupt in ecosystems, since the trade of animals brought in invasive species - a species that is not native and, for that reason, tends to spread and damage the environment.
