If a response increases a disturbance, the system is classified as a feedback system.

If a response increases a disturbance, the system is classified as a positive feedback system.

Further Explanation:

A typical response is a reaction that occurs after something is done. It is an answer to a question that is in the form of a reaction. Feedback is defined as the information that is gained about a reaction to a product. This information allows for the modification of the product. Feedback loops on the processes that result in triggering a certain result based on the change in the system results.

If a response is responsible for an increase in the disturbance, the system can be termed as a positive feedback system. For example, one entity produces a second entity, which in turn produces more of the first entity. It can be concluded that positive feedback depends upon the input.

The response that results in a decrease in the disturbance is known as the negative feedback loop. A typical example of a positive feedback loop is change in the physiology of the body concerning the body temperature. When the body temperature decreases, the brain sends signals to the body to change the physiological aspects of the body to increase the temperature of the body.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
