Answer 1

Physiological adaptations can be hard to identify primarily because they can happen on a microscopic level inside the body. Many of the changes that occur as adaptations may not be visible externally, such as alterations in cellular structures, biochemical pathways, or hormonal levels. These internal changes may not manifest in noticeable physical traits, making them difficult to observe without specialized techniques or equipment.

The other options, such as organisms camouflaging adaptations, changing behavior, or not passing them on, do not accurately capture the essence of why physiological adaptations might be challenging to identify.
