When comparing unisex flowers, the males will usually have many stamens rich with pollen while the females only have pistils. The appearances of pistils and stamens vary between species, however, pollen is often brown or orange, making the anther and filament distinct, while the pistil is usu...
Lions, as the only social cats, live in groups called prides. Prides consist of between three and 40 lions, with 15 being the average. Females commonly remain with their birth pride for life, but males leave after two to four years. There are generally only one or two adult male lions ...
Forum: Chemistry S I One difference between GR and quantum mechanics I wanted to ask about a potential difference between general relativity and quantum mechanics phenomena - that we are observing them at different moments in time. Because causality has a speed limit (##c##), every point in...
there is astronomy, the study of celestial objects and the physical universe. On the other hand, we have astrophysics, a branch of astronomy that employs principles of physics and chemistry to elucidate the birth, life, and death of stars, planets, galaxies, nebulae,...

The Main Differences Between Mass and Weight How Much Do You Weigh on Other Planets? While a person's mass doesn't change elsewhere in the solar system, theaccelerationdue to gravity and weight varies dramatically. The calculation of gravity on other bodies, as on Earth, depends not just on...
The ship lies on a parallel line separated from the former by the difference between the observed and computed zenith distances. Opinions will differ as to the relative merits of these rival methods of reduction, but at least it may be said that the method given in this volume is sound and...
An atom can be an ion, but not all ions are atoms. These are the important differences between an atom and an ion.
An infinitesimal part of anything of the same nature as the entire magnitude considered; as, in a solid an element may be the infinitesimal portion between any two planes that are separated an indefinitely small distance. In the calculus, element is sometimes used as synonymous with differential....
excluding Earth itself. Astronomy is a recognized branch of science that uses multiple disciplines to make sense of the universe. Mathematics, chemistry, physics, and all manner of sophisticatedinstruments come into play as scientists study the starsan attempt to discover answers to some of the most...
