frog

frogs live their first part of their lives in water so they need gills but after metamorphosis they live on land so they need lungs.
On May 14, 1796, Jenner<span> took fluid from a cowpox blister and scratched it into the skin of James Phipps, an eight-year-old boy. A single blister rose up on the spot, but James soon recovered. On July 1, </span>Jenner<span> inoculated the boy again, this time with smallpox matter, and no disease developed. The </span>vaccine<span> was a success.</span>
The answer is either -unfenced land where grass or grass-like vegetation grows and is the dominant form of plant life, or <span>-an enclosed field covered with grass or similar plant and suitable for grazing by livestock.
I am not sure which though.
I hope this helps you!
Have a nice day! :)</span>
