Problem 4 - Biology: The Dynamic Science

Question

Arnold's experiments on the feeding preferences of garter snakes demonstrated that food choice is largely governed by a snake's: a. early experiences. b. genetics. c. size and color. d. diet while it was developing inside its mother. e. trial-and-error learning.

Step-by-Step Solution

Answer

The factor that largely governs the food choice of a garter snake is its genetics.

Step 1: Understand the Question

The question is about the factors that largely influence the feeding preference of garter snakes. Five options have been provided which include: early experiences, genetics, size and color, diet while it was developing inside its mother, and trial-and-error learning.

Step 2: Process of Elimination

Size and color are typically not factors that govern a snake's food choice, so we can rule out option 'c'. A snake's diet while it is developing inside its mother affects its development but not necessarily its food choices, so we can rule out option 'd'. Trial-and-error learning involves an individual learning from the consequences of its actions, which could be a factor but is not the primary factor governing a snake's food choice, so we can rule out option 'e'.

Step 3: Choose the Correct Answer

Between the remaining options 'a' and 'b', the main factor governing a garter snake's food choices is 'b' genetics. Garter snakes, like other animals, are instinctively drawn to certain foods and this preference is genetically determined.
