Answer:
Feedback
Explanation:
A technological system is a system that consists of components constructed to work together in order to process an input to an output/result. These components or parts that make up a technological system are as follows: input, processing, output and feedback.
- The input is what is taken in by the system.
- The process is the series of occurrences conducted by the internal parts of the system to bring about an output.
- The output is the final result of the system.
- The feedback is how the system should work in comparison to how it is working.
Among all these parts of a technological system, the part that is OPTIONAL i.e the system can function without, is the FEEDBACK.
Answer:
All EeWw (100%)
Explanation:
This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for earlobe but homzygous recessive for hairline i.e. (EEww).
The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:
eeWW - eW, eW, eW, eW
EEww - Ew, Ew, Ew, Ew
Using this gametes in a punnet square, the following proportion of offsprings will likely be produced:
All EeWw
