Answer: (C)
Rats can learn to run complex mazes even without food rewards present.
Explanation:
Biological predisposition to learning is brought about by an internal inherited quality that increases the likelihood of having a condition or exhibiting a certain pattern of behavior.
It occurs in humans and animals and has to do with genes passed down from parents to children.
In this case, the genetical makeup of the rats can cause them to learn to behave in a certain way over time.
Answer: toeboard
Explanation: The Occupational Safety and Health Administration defines the Walking-Working surfaces regulation for the secure construction of stairs in industrial environments. For platforms or walls that are 4 feet or higher above the ground and do not have surrounding walls, it is mandatory to build a standard railing around them. In cases where there is a moving machinery, people can pass or there is an equipment which would be harmful when falling objects come in contact with it, the railings must have a toeboard.
A toeboard is an equipment fixed vertically to prevent items from falling for the platform.
An uncommon, unexpected, or an individual drug response thought to result from a genetic predisposition is called idiosyncratic reaction. These are also called type B reactions. They are side effects that happens rarely and mostly cannot be predicted. One example is an asthma attack due to the reaction to aspirin.
