Which of the following prefixes indicates "milk"?

1. Galact-, lact-

2. Cardi-

3. Neur-

4. Thromb-

The correct answer is: Galact-, lact-

The prefix that indicates "milk" is found in the terms "galact-" and "lact-". Both of these prefixes are derived from terms used in anatomy and physiology related to milk production and composition. For example, "lactation" refers to the process of producing milk, while "galactose" is a type of sugar found in milk. In contrast, the other prefixes do not pertain to milk. "Cardi-" relates to the heart, as seen in words like "cardiology," which is the study of the heart and its functions. "Neur-" pertains to nerves and the nervous system, as in "neurology," which focuses on nerve function and disorders. The prefix "thromb-" is associated with blood clots, appearing in terms like "thrombosis." Thus, the correct identification of "galact-, lact-" as prefixed terms indicating "milk" is based on their direct connection to milk and its biological relevance.
