I would say energy myself, and this is because energy plays a key role in all of these. With trophic levels energy is being transferred amongst the levels. Food chain's is a map of how the energy is passed along the chain. Food web is a web of how energy is transferred, and this is why I would say energy is a keyword.
        
                    
             
        
        
        
Answer:B) Technician B 
Explanation:ECT(ENGINE COOLANT TEMPERATURE) is a sensor present in the coolant Temperature sensor that checks and transmits the Temperature to the ECM(engine control module). This helps to regulate the fueling time, speed and other factors that can impact the Temperature of the engine.
Stepped ECT circuits require different Internal resistance inside the PCM(power-train control module) is a combined control which includes the ECU(ENGINE CONTROL UNIT) AND TCU(TRANSMISSION CONTROL UNIT). The same sensor can be used for both the stepped circuit and a circuit that is not stepped.

Additional detail found elsewhere: (T = Tall and t = short) 
Answer:
All are expected to be tall
Explanation:
We are told that the T allele produces the tall trait, and the t allele produces the short trait. 
Because the tall allele is denoted by an uppercase letter, it means it is the dominant allele, meaning if it is present even in one copy, the trait will be expressed. This is in contrast to the recessive short allele, 2 copies are needed for the trait to be expressed.
Individuals have 2 copies of every gene. Offspring that are TT, Tt, TT, and Tt all have at least one copy of the T (tall allele). Because this is the dominant allele, that means all of these offspring would be expected to be tall.
