Which is a limitation of a scientific model?
a) models make a system easier to understand.
b) models can be used in almost any situation to explain a system.
c) models are more accurate than observing the real object or system.
d) models are not the "real thing" so it will never correctly represent the system in all respects.

The correct option is D)  Models are not the "real thing" so it will never correctly represent the system in all respects.

Explanation:

Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.

As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.

integrated circuit (ic) is defined as a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. a functional electronic circuit requires transistors, resistors, capacitors, inductors, etc., and the connections between them.

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
