Question 18

In the context of biology (and genetics related to biological mechanisms), the body's hunger and satiety mechanisms are influenced by biological processes (like hormonal signals, neural responses) that have genetic and biological underpinnings. So the statement is true.

From biological and developmental perspectives, humans are born with a natural preference for sweet - tasting foods. This is related to the evolutionary and biological basis of taste preferences, as sweet foods (like those with sugars) are often a source of energy, and infants show an innate liking for sweet tastes.

Answer:

True
