Many species of plants can absorb heavy metals: those with atomic number greater than 20.
Some are essential for plant growth. These include
Mg, Mn, Fe, Ni, Cu, Zn, and Mo
Plants can absorb other heavy metals, but we don’t know their biological function. Among these are:
Co, Se, Cr, Cd, Ag, Hg, and Pb
Answer:moon phases
Explanation:
Moon phases because the moon phases changers every day
Answer:
d. it’s reduced
Explanation:
An oxidation-reduction reaction, commonly known as REDOX reaction is a type of reaction that involves the transfer of electrons from one atom to another characterized by a change in oxidation number. The atom that loses electrons is said to be OXIDIZED while the atom that gains electrons is said to be REDUCED.
Therefore, in this question describing the half reaction of an oxidation reduction to show that iron atom (Fe) gains electrons. This indicates that the IRON atom is being REDUCED because it's oxidation number will reduce after gaining electrons.
That’s the SI unit of energy or work
Answer:
60 kilometres per hour is the slowest rate of travel
Explanation:
we convert
20 kilometer per minute into kilometer per second
it comes out 1/3 kilometer per sec
