How is the concept of homeostasis related to disease and aging provide examples?
Alinara [238K]

Answer;

-Because of Homeostatic imbalance as we age our body organs become less efficient, and our internal conditions become less and less stable. This event has a risk for illness and produce changes we associate with aging.

Explanation;

-Homeostasis is the body's ability to maintain a relatively stable internal environment even though the outside world is constantly changing. It involves both positive feedback Loops and the negative Feedback loops.

-Aging is a general example of disease as a result of homeostatic imbalance. As an organism ages, weakening of feedback loops gradually results in an unstable internal environment. This lack of homeostasis increases the risk for illness and is responsible for the physical changes associated with aging.

Which of these conditions indicate positive feedback has occurred?
aleksklad [387]

Answer;

A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.

Explanation;

-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.

-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.

-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.

A model for a​ company's revenue from selling a software package is ​R(p)equals=−2.52^2400​p, where p is the price in dollars of
dsp73

A model for a​ company's revenue from selling a software package is ​R(p)=-2.5p² + 400​p, where p is the price in dollars of the software. What price will maximize​ revenue? Find the maximum revenue.

Answer: p = $80,  R = $16,000

Step-by-step explanation:

The maximum is the y-value of the Vertex.

Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x:

x=\frac{-b}{2a}

R(p) = -2.5p² + 400

     a= -2.5  b=400

p=\frac{-(400)}{2(-2.5)}

         = \frac{-400}{-5}

        =80

∴ In order to maximize the value, the company will sell the software package for $80

Step 2: Find the maximum by plugging the p-value (above) into the given equation.

R(80) = -2.5(80)² + 400(80)

         = -16,000 + 32,000

         = 16,000
