Generate and refine what?
Based on the number of years, and the number of nesting sites, the exponential function that best models the data is B. n(x) = 46,797(0.93)ˣ.
<h3>What function best models the data?</h3>
You can find the correct function by testing out the options with the given x value to see if it correctly predicts the number of nesting sites.
Function n(x) = 25,956.80(1.08)ˣ
Assuming x is 3:
= 25,956.80(1.08)³
= 32,698 sites
This function does not predict the correct number of sites which is 40,513.
Function n(x) = 46,797(0.93)ˣ
Assuming x is 3:
= 46,797(0.93)³
= 37,438 sites
This is closer to the predicted number of 40,513 sites with some discrepancy.
In conclusion, option B is correct.

A flatworm has a simple nervous system with two nerve cords running down both of its sides. It also has two simple brains, and two eyespots that help sense light. While a fish's nervous system is comprised of a central brain and a spinal cord along with many branching nerves, which allows them to sense things around them.
Explanation:
A flatworm has a very mild nervous system with pair nerve cords moving down each side. It has two single brains called ganglia, which are pure packages of nerves. It has two eyespots that support it sense light. A flatworm has a gastrovascular hole with one opening.
Fish have extremely advanced nervous systems organized around a brain. Fish brains have rare clearly visible parts. Back to the brain is the spinal cord, which is the deep dorsal nerve cord that identifies chordates.
It is possible to replace the CO2 cylinder in an inflatable PFD each time the PFD is inflated.
<h3>What is an inflatable PFD?</h3>
An inflatable PFD is a specific inflator mechanical device based on a CO2 cylinder that fills a given sac with air.
Inflatable PFDs need to have to maintaining different types of safety measures to avoid the failure of the device (especially in emergency situations).
Inflatable PFDs can be classified according to their features into Type I, Type II, Type III, and Type V (for example, Type III allows to buoy to more than 15 pounds), where Type IV PFDs are not inflatable.
In conclusion, it is possible to replace the CO2 cylinder in an inflatable PFD each time the PFD is inflated.
