Both J.C. Adams of Cambridge and U.J.J. Le Verrier of Paris noticed anomalies in the orbit of Uranus. Because of Newton's Universal Gravitation, they predicted that there was another undisocered planet affecting Uranus' orbit. They predicted mathematically where the new planet (Neptune) would be. Both came very close. They both had observational astronomers (Challis and Galle) look for the planet. Galle already had a star map and found it first, and it was a great triumph for Le Verrier. Adams and Le Verrier are considered co-discoverers mathematically and Challis and Galle are considered co-discoverers observationally.
Because a planets atmosphere was pulling Uranus and that was Neptune.
Yes, astronomers had noticed increasing errors in their models for the orbit of Uranus and eventually ruled out many explanations besides an outer planet that could be perturbing its orbit.
Neptune and Pluto are not the same discovery at all.
it was unknown until they found a gravitational pull on Neptune
Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
Neptune has 13-14 moons. Scientists are not sure whether it is a moon or an asteroid.
One day while scientists were exploring the sea floor, they discovered sea-floor spreading, thus proving Wegener's hypothesis to be correct.

There are two scientists. Goldstein is the first person that found it.

Scientists can see Neptune with telescopes. Also, they have many photos of it from when the Voyager 2 passed by.
It was because of anomalies un Uranus' orbit that Neptune was discovered.

Yes, scientists say Neptune is shrinking as we know it.
