Answer:
The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells. Here we will consider what has recently emerged on the evolutionary histories of several key aspects of nuclear biology; the nuclear pore complex, the lamina, centrosomes and evidence for prokaryotic origins of relevant players.
Answer:
Reduced
Explanation:
M + e⁻ ⟶ M⁻
Reduction is the gain of an electron.
Answer:
Water (H2O) and Sodium (Na) are reactants.
Explanation:
2H2O+2Na......2NaOH+H2
In the above reaction the water (H2O) and sodium (Na) are reactants and sodium hydroxide (NaOH) and hydrogen are products.
And this is the single displacement reaction.
It is added because NH3 is added
The ammonia or NH3 molecule is a neutral molecule therefore it has a zero net charge. Nitrogen can covalently bond to three other atoms where as hydrogen can covalently bond to one other atom. In this case, the bonds are stable by sharing all the valence electrons of atoms leaving no charge.<span />
