All of the traits passed biologically from parent to child are known as



• risk factors.
• behavior.
• heredity.
• environmental influences.

The correct answer is "heredity." Heredity refers to the transmission of biological traits or characteristics from parents to their offspring through genetic information. These traits can include physical features, such as eye color or height, as well as predispositions to certain diseases or conditions. To determine the correct answer, you could first understand the meanings of the other options:

- Risk factors: Risk factors are conditions or behaviors that increase the likelihood of developing a certain disease or health condition. They can be influenced by various factors, including genetics, behavior, and environment, but they are not synonymous with the genetic traits passed down from parents to children.

- Behavior: Behavior refers to the actions or conduct of an individual. While behavior can be influenced by both genetic and environmental factors, it does not encompass the genetic traits that are inherited from parents.

- Environmental influences: Environmental influences refer to the factors in a person's surroundings that can affect their development and health. This can include physical, social, cultural, and economic factors. While the environment can interact with genetic traits to influence certain outcomes, it does not encompass the genetic traits themselves.

To arrive at the correct answer, you can eliminate the options that do not fit the definition of traits passed biologically from parent to child. In this case, "heredity" is the most appropriate term to describe this type of biological transmission.
