B, because earths gravity if pulling on the moon and since velocity pulls it it’s like earth tied a string to the moon and the moon goes in a circle
In the electrolytic cell, depending on the polarity of the battery, either a more vigorous reaction (though the same as the voltaic cell) would occur, or the reverse would.
True, oxygen gas ignites a glowing splint
Answer: There are many foods who have trace elements like seafood, legume, vegetables, tomatoes, bananas, eggs, fishes, meat.
Their five mainly functions are accept or receive electrons in redox reactions, act like cathalytic centers which are necessaries to live, control biologics process like the hormon activation and gen expression, provide stability, 3d structures in important molecules.
Explanation: Trace elements participate in redox reactions because they have acid-base components which alkalize o acidify the way, protecting the organism from free radicals.
Biological sources which are controlled by trace elements are:
- assimilation of ATP
- methabolic sources relationed with insuline
- oxygen transport in the organism
- stomach acid formation
- 3d structures from important moleculess are mantained by balance of electrons which make up the atoms from the molecule.
