Explanation:
Plants are autotrophic organisms which prepare their food with the help of photosynthesis. Plants can have both asexual or multi-sexual reproduction.
Amoeba is a single celled eukaryotic organism. It moves through pseudopodia and it does not have any definite shape. Amoeba can have only asexual reproduction.
The given functions for amoeba and plants are sorted as follows.
Functions of Amoeba:
- has only offspring with identical genes and traits.
- surrounds and engulfs food particles.
- move freely in their environment.
Functions of Plants:
- makes food from carbon dioxide,water, and sunlight.
- can have offspring with different genes and traits.
An energy profile of a reaction tells you whether it's endothermic or exothermic, the energy of the products and reactants, the activation energy needed for the forward (Ea) and reverse (Ea') reactions, the change in energy (∆E), and the energy of the activated complex.

Answer:
Only Mn⁺² is present.
Explanation:
- When an aqueous solution of NaCl is added, the Cl⁻ species is introduced. In the presence of Cl⁻, Hg₂²⁺ would precipitate as Hg₂Cl₂.
- When an aqueous solution of Na₂SO₄ is added, the SO₄⁻² species is introduced. In the presence of SO₄⁻², Ba⁺² would precipitate as BaSO₄.
No precipitate formed when either of these solutions were added, thus <u>the sample does not contain Hg₂⁺² nor Ba⁺²</u>.
- Under basic conditions Mn⁺² would precipitate as Mn(OH)₂. A precipitate formed once the solution was made basic, so <u>the sample contains Mn⁺²</u>.
