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.
Answer:
offering a specific hypothesis and associated prediction to explain why the car won't start
Explanation:
A hypothesis can be defined to be a wise guess. It is a proposed explanation that is given on little evidence. A specific hypothesis can be described as a statement if prediction.
By telling my friend that his car would not start because his battery may be dead, and he has to jumpstart from a good battery, I have given him a specific hypothesis and also a predicted explanation as to why his car has refused to start.
Answer:
Dr. Greenway- behavioral perspective; Dr. Cech- cognitive perspective
Explanation:
Behavioral perspective- This is a theoretical perspective through which behavior and learning are described in terms of stimulus-response (SR) relationships. According to behaviorists, a person's behavior is a result of the interaction with the given environment. There are two processes through which people learn and develop skills from their environments: Operant conditioning and Classical conditioning.
Cognitive perspective- This involves the understanding of mental processes, for example, perception, memory, problem-solving, and thinking. It states that our thought processes influence the way we behave.
