Rasek [7]
The correct answer is serotonin.

Serotonin is a neurotransmitter (NT) produced in the human body. It is known as the "happiness" or "feel good" chemical.

valina [46]

The pollination of an orange tree's flowers by honeybees best illustrates mutualism.

Mutualism refers to the ecological interaction between two or more species in which each species benefits.  Mutualism is a type of ecological interaction that occurs frequently. Most vascular plants have mutualistic interactions with mycorrhizae, flowering plants are pollinated by animals, vascular plants are dispersed by animals, and corals have zooxanthellae, among many others. Mutualism contrasts with interspecific competition, in which each species loses fitness, and exploitation, or parasitism, in which one species gains at the "expense" of the other.

Mutualism is frequently confused with two other ecological phenomena: cooperation and symbiosis. Cooperation most commonly refers to increases in fitness caused by within-species (intraspecific) interactions, but it has also been used (particularly in the past) to refer to mutualistic interactions, and it is sometimes used to refer to non-obligate mutualistic interactions.

One of Abraham Lincoln's greatest attributes was his ability to recover and learn from failure. The quality of perseverance seem
Naily [24]

For Lincoln, learning how to persevere also meant learning how to adapt. Based on your reading of Shenk's article, please identify three of Lincoln's most successful adaptation strategies (skills, habits, or ways of thinking) that helped him use his struggle with depression to accomplish worthy goals.

Answer:

The three of Abraham Lincoln's most successful adaptation strategies are:

1. Skill - Poetry: Writing of poetry or story telling.

2. Habit - Self discipline or Meditation.

3. Ways of thinking: Transcendent thought or Belief of higher purpose in life.

Explanation:

Skill: from the Shenk's article, it was believed that, Abraham Lincoln resulted to writing or poetry to fight off his depression by conveying his gloomy thoughts or mood in to poetry, while also writing about his perception of life and events to relief himself of the affliction

Habit: Shenk suggested that Lincoln was self disciplined , and most of the times would meditates rather than mingle with the public whenever the opportunity presents itself, which in turn, helped him to gain control and stability over depression.

Ways of thinking: Shenk also believed that the adaption of Lincoln to depression is not because of finding orthodox medicine or remedy, but by chanelling his thought to the belief that he was created for higher purpose: the thought that affliction is a sign of test, renewal and spiritual advancement, which swayed his opinion about the depression
