Answer:
By presenting the results in a poster session.
Explanation:
Several scientists from different countries are asked to examine the results of an experiment before a journal will print it.
When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.
Neurons- transmit nerve impulses. And Neuroglial cells- are non-conducting “support cells” of nervous tissue.
