Answer:
In the deep ocean layers where the sunlight does not reach, these organisms that are chemoautotrophic use sulfides from the hydrothermal vents to perform chemosynthesis instead of photosynthesis.
Explanation:
Chemoautotrophic organisms are the ones that are adapted to the absence of sunlight. Such organisms identify electron donors in their vicinity and derive energy from the oxidation reactions that these electron donors (mostly, inorganic compounds) undergo.
The major reason for the development of such a trait in these organisms is the depth that they live at. On deep-sea floors, there is an abundance of sulfides. Thus, the organisms living on there make use of the sulfides to fix carbon and obtain energy the required energy to sustain.
The process of chemosynthesis occurring on deep-sea floors due to the presence of carbon, sulfides, and oxygen culminates in the production of organic materials as an end result which the organisms feed on and sustain even when there is no sunlight available. These organisms majorly belong to the bacteria species called Archaea and Extremophiles.

Explanation:
Answer: differential reinforcement (DR) procedure
Explanation: Functional communication training (FCT) is a method used to teach individuals with severe behavioral problems acceptable behaviors by reinforcing alternative behaviors. It is a form of Differential Reinforcement.
FCT sees behavior as a way of communication and is appropriate for people with learning disabilities or speech difficulties. FCT establishes the factors in the individual’s surrounding that is enforcing the undesirable behavior then designing a new response which is acceptable to the factor or event.
For example if a student screams when he does not understand a question or topic in class, a teacher may teach him a simple sentence or sign language which serves as an alternative way to express his confusion.
There are several ways in which we could justify this statement, but also many ways in which we would be able to challenge it.
In terms of support, we can argue that this was the case because the cultures of America did not have any significant contact with the cultures of Africa or Oceania until the arrival of the Europeans. We can also support this by the fact that the Andean cultures and the Mesoamerican cultures had no contact with each other.
However, there are several factors that show that this was not the case, or that the claim might be exaggerated. For example, we know that many groups in Africa had extensive interactions with each other. For example, the expansion of the Bantu that took place over large regions in Africa. Another challenge could be the extensive contact that many Mesoamerican groups had with each other.
