Final answer:
The concept of lines and sines varies by context: Asch's experiments involve visual line comparison in psychology, while sines are a mathematical concept. The true/false question about wave amplitudes relates to physics, and whether two numbers are the same for F and C's independence is a statistics concept. Muscle fiber proportions vary among individuals in biology.
Step-by-step explanation:
The statement about lines and sines being the same between individuals is presumably related to Solomon Asch's conformity experiments where participants were asked to compare the length of line segments. In biology, this concept does not apply as lines in this context are a matter of visual perception studied in psychology. Meanwhile, sines refer to a mathematical function and do not relate to individual biological differences.
When discussing the statement about the amplitudes of waves adding up only if they are propagating in the same line, it relates to physics, specifically wave interference. The statement is true; for waves to constructively interfere and their amplitudes to add up, they must be coherent and propagate in the same direction.
The question concerning if two numbers being the same results in factors F and C being independent is likely from statistics, where independence of variables is a key concept. If the numbers, which could represent probabilities or certain statistical measurements, are not the same, then it would suggest that F and C are not independent.
In another biology context, the growth curves of populations are discussed, highlighting the concept that while the overall S-shape of a logistic growth curve would be the same, the actual values and carrying capacities can vary across different populations.
Lastly, the statement about all people having the same proportion of slow-twitch to fast-twitch muscle fibers is false. The composition of these fibers varies from individual to individual and can be influenced by genetics and training.
