The process is called peer review. Scientists are obligated to publish their research in scientific journals. The number of publications a scientist has will impact his or her career path and advancement. When a scientist finishes a study, he/she and his/her collaborators will write a manuscript outlining and discussing the results of the study. This manuscript will be sent to a journal for publishing. There are usually several journals publishing within each field, with some more prestigious than others, as indicated by an impact factor. Journals such as Science and Nature have the highest impact factor as they have the greatest readership. The editor of the journal will send the manuscript off to other scientists working in the same field, and will ask them to 'peer review' the manuscript to determine whether the paper deserves publication, whether it requires corrections, or whether is should be rejected outright. Ideally, papers should be rejected because of bad science, and not because the results contradict previous studies or current scientific theory.

Lost phosphorus is actually recycled through the processes of mineralization, reabsorption, dissolving, and precipitation.
Hi there!
Kinetic Energy (1/2 · mass · velocity²) occurs when an object is in motion, or a force is occurring on the object. An example would be a car in motion.
Potential energy (mass · height · gravity ) is obtained when an object has the ability to do work. An example would be an object on a shelf. It has the potential to fall, and this would cause the potential energy to become converted into kinetic energy.
-----------------------------------------------------------------------------------------------------------
Looking at the examples in the table, we can sort them as such:
Girl swimming laps- Kinetic energy because the girl is in motion.
Boy on diving board - Potential energy because the boy is not in motion, but has the potential to be in motion.
Girl hitting volleyball - Kinetic energy because the volleyball is in motion.
Boy holding volleyball- Potential energy because the volleyball is stationary and has the potential to be in motion.
Therefore, the correct table is table 1.
Answer:
Classification system changes because the scientists find new evidence in their studies.
Explanation: The world is always changing and growing and dying as well as developing, so over time things change. For example, as you grow up do you stay the same? No, you notice the physical changes happening, well thats sort of like how the earth and its ways are always changing as well.
