Where does the thermionic emission occur in cathode rays tube?
Basically the thermionic rays are fast moving electrons. They originate in the region having an excess of electrons. So originate from the cathode.
What are the differences between thermionic emission and evaporation?
Thermionic emission occurs when electron leaves the surface of metals while evaporation occur in liquid when strong electron gain energy and escape the liquid surface in gaseous form
Does ATP production occur during fight or flight response?
yes
Why does mottling occur during tablet production?
Mottling occurs when the dye migrates during the granules' drying process.
If an enzyme is absent during polypeptide production a mutation can occur?
This is a true statement. If an enzyme that is involved in DNA replication is not there, then a mutation can occur.
Do most inheritable differences occur during the production of gametes due to gene shuffling?
yes
What happens when energy transformations occur in a coal fired power plant during the production of electricity?
nothing
In what part of a chloroplast does glue close production occur?
The production of glucose takes place during the light independent reactions (Calvin cycle) in the Stroma.
What happens inside an extinguisher when the handle is pressed?
Combustion occur and emission
When does carbohydrate production occur in a chloroplast?
During The Calvin Cycle cycle, sugars are produced in the chloroplast.
How many times emission occur in radioactive series?
around ten 10
Does beta radiation results in the emission of electrons?
In beta radiation, an emission of electrons can occur due to beta decay. A neutron can disintegrate into protons and electrons.
