Answer:
on the surface rapidly
Explanation:
Obsidian glassy texture indicates that the rock formed on the surface rapidly.
Like every other magma, the condition of the environment determines how the magma cools and solidifies.
- When magma cools rapidly, nucleation centers will be difficult to come- by ..
- At nucleation centers, minerals aggregates and grows to form different grain sizes.
- When rapid cooling occurs, not enough time is given for the aggregation around the nucleus.
- This leaves a rock mass that is finely grained.

Huh!!!Where is the question???..?
Answer:
Mutualism
Explanation:
Mutualism is also referred to as inter specific cooperation, a phenomenon in which two organisms from two different species co-exist in such a way that both get benefit from each other, either from their activities or from their fitness. Such behavior is commonly termed as cooperation.
Here in example, we see that saguaro cactus provides food for the white-winged dove through its large fruit. The bird eats that fruit but along with fruits it also ingests the seeds present in fruits. SO, when the bird flies to some new location, it drops the seeds there. In this way cactus can colonize new lands and spread offspring in new places while birds get their food. Both get benefit so it was a mutulalistic relationship.

The first historical record associates the beginning of sugar in the Americas with Christopher Columbus' initial and epic voyage of the discovery of the New World in 1492.
The sugar cane plant is native to Southeast Asia and in Europe had already created an appetite for more through the Eastern trade routes. These were of course difficult routes that included trade caravans over land and water to reach Asia from Europe.
With Columbus the initial planting of sugar cane occurred in the Dominican Republic. The Caribbean islands maintain a perfect tropical climate for the plant and as such, flourished. Other colonizers, like the British, Portuguese and French soon followed suit within their own colonies spread throughout the New World.
The Portuguese had transplanted or moved some of the seedlings, or small plants from the Dominican into Brazil and other areas of their colonized lands. In fact, Brazil is the largest producer of sugar cane in the world today.
The desire for more sugar during this early settlement, led to a "triangle of trade". In order to satisfy the need for production of sugar, ships sailed to the western coasts of Africa to bring slaves to work the sugar plantations. After depositing the slaves, the ships would pick up sugar and rum, an alcohol created from sugar, and bring these goods back to the European powers. This completed the cycle for the ships, which would then return to Africa to gather more slaves.
By 1505, this trade route was set up and going strong. And for the next 300 years or so, would remain in effect.
