The statement that is true is:
"As evidence changes, scientific theories can also change."
Scientific theories are based on the best available evidence and can be revised or replaced as new evidence emerges.
Scientific theories describe natural phenomena, whereas scientific laws explain natural phenomena.
Scientific theories only involve finding evidence to explain phenomena.
If a single study or inference is wrong, a scientific theory can be invalidated.
As evidence changes, scientific theories can also change.

The statement that is true is:
"As evidence changes, scientific theories can also change."
Scientific theories are based on the best available evidence and can be revised or replaced as new evidence emerges.
The true statement is:
"As evidence changes, scientific theories can also change."
Scientific theories are subject to modification and refinement based on new evidence and insights. The other statements contain inaccuracies regarding the roles of scientific theories and laws, and the nature of scientific validation.
The most accurate answer is:
"The scientist would need to study many samples of different species over several generations to get enough evidence to propose a theory."
A scientific theory is generally built upon a substantial body of evidence collected from multiple studies and observations, rather than a single study or a limited examination of samples. Thus, extensive research and replication are important for proposing a robust scientific theory.
The most appropriate answer is:
"The scientist would need to study many samples of different species over several generations to get enough evidence to propose a theory."
Developing a scientific theory requires a comprehensive understanding based on extensive evidence. This often involves multiple studies, data collection, and replication across various conditions and samples to ensure the findings are reliable and applicable.
The statement that best describes a scientific theory is:
"Jose explained that all planets orbit around the sun in an elliptical path."
This statement reflects a scientific theory (Kepler's laws of planetary motion), as it provides an explanation for a natural phenomenon based on underlying principles and evidence. Scientific theories are typically broad explanations supported by a significant amount of evidence. In contrast, the other statements describe predictions or explanations that are not framed as theories.
The statement that best describes a scientific theory is:
"Eva explained that two brown-haired parents had a child with red hair due to dominant and recessive genes."
This statement explains a biological phenomenon using established genetic principles, describing the underlying mechanisms (dominant and recessive inheritance) that lead to a specific outcome. It reflects the explanatory nature of scientific theories, which seek to provide understanding of why certain phenomena occur based on empirical evidence.
While Jose's statement about planetary orbits is also valid, it is more specific to a particular observational fact, while Eva’s explanation incorporates a broader underlying mechanism in genetics.
