true
false

Explanation:

Question 1

In biology (a subfield of Natural Science), the differences among individuals of a species are called "variation" (specifically genetic variation or phenotypic variation). This is a fundamental concept in evolution and genetics, where variations arise from mutations, genetic recombination, etc., and are the raw material for natural selection.

• For "Any inherited characteristic that increases an organism’s chance of survival": This is the definition of "adaptation". Adaptations are traits that help organisms survive and reproduce in their environment.
• For "Survival of the fittest": This is a phrase that describes "natural selection". Natural selection is the process where organisms with favorable traits (the fittest) are more likely to survive and reproduce, leading to the evolution of populations.
• For "The ability of an individual to survive and reproduce in its specific environment": This is the definition of "fitness". Fitness in evolutionary terms is about an organism's reproductive success in its environment.

Adaptations can be both physical characteristics (like the shape of a bird's beak) and behavioral features (like migration patterns of birds or social behaviors in animals). Behavioral adaptations are also important for an organism's survival and reproduction. So the statement "Adaptations can be physical characteristics but not more complex features such as behavior" is false.

Answer:

variation
