Answer Details
When bacteria swim from cold to warm regions, this is known as positive thermotaxis. Thermotaxis refers to the movement of organisms in response to changes in temperature. Positive thermotaxis means that the bacteria are attracted to warmer temperatures, so they swim from cold regions to warm regions. This behavior is thought to be an adaptation that allows bacteria to find environments that are optimal for growth and survival.
