Density Change is when the mass/weight of an object modifies by sometimes its environment. It relates to pond life by how much weight thats in the pond and the mass of creatures, such as frogs and crocidiles
The
first observation was that, natural selection might itself be variable because
it is dependent with the different seasons the environment have. Second, the
frequency of small-beak depth Geospiza fortis became lesser on an island when a
large-beak-depth was introduced because the large-beak-depth species has
greater survival rate especially during dry season were they can eat larger and
harder seeds as compare to the small-beak-depth birds.
P^2 (Earth years) = a^3 (astronomical units)
P = period
a = semi-major axis of elliptical orbit

Kepler's third law of planetary motion is a mathematical relation between orbital periods and distances. It allows astronomers to measure masses of celestial objects. Johannes Kepler went to work for Tycho Brahe near the end of Tycho's life. When Tycho died, Kepler used Tycho's data to deduce three laws of planetary motion. Because Tycho's data were far more accurate than any previously collected data on planetary positions neither Ptolemy's nor Copernicus's models of the cosmos worked.
Answer:
The answer is Gail.
Explanation:
The more trials someone conducts, the more accurate their data will be.
