Plants and animals are multi-cellular organisms composed of eukaryotic cells, while bacteria are single-cell prokaryotic organisms. Each eukaryotic cell of a plant or animal includes a central nucleus containing DNA and membrane-bound organelles, such as endoplasmic reticulum and mitochondria. A bacterial cell has no nucleus or membrane-bound organelles.

The mass numbers of the different isotopes of that element are averaged according to their respective abundances in nature.
Answer:
The coffee is the solvent. The sugar is the solute. The sweetened coffee is the solution.
Explanation:
Answer:
Wt%H₂SO₄ = 10.2% (w/w)
Explanation:
1.61 molal H₂SO₄ = 1.61 mole H₂SO₄/Kg Solvent = 1.61 mole(98 g/mole)/Kg Solvent = 113.68 g H₂SO₄/Kg Solvent
Solution weight = 1000 g solvent + 113.68 g solute = 1113.68 g Solution
Wt%H₂SO₄ = (113.68 g/1113.68g)100% = 10.2% (w/w)
