Answer:
Nucleus
Explanation: it is the center of the atom, and contains protons and nuetrons
Organism are made up of organic molecules consisting of carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus.
The answer is B.
he mass defect of the helium nucleus ⁴He₂ is 0.030377 u
Further explanation
Mass defect means the difference between the mass of particles forming an atom with an atomic mass.
Δm = mass defect ( u )
mp = mass of proton ( u )
me = mass of electron ( u )
mn = mass of neutron ( u )
M = atomic mass ( u )
A = mass number
Z = atomic number
Let us now tackle the problem !

Mass of KMnO4 required : 31.607 g
<h3>Further explanation
</h3>
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products
Reaction
2KMnO₄ → K₂MnO₄ + MnO₂ + O₂
mol of O₂ :
mol ratio KMnO₄ : O₂ = 2 : 1
mol of KMnO₄ :
mass of KMnO₄ :
MW KMnO₄ : 158,034 g/mol
One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but when we talk about osmosis, only the solvent molecules (water molecules) cross the membrane
I'm not sire which one it is but hope i helped
