Active transport is the process by which dissolved molecules move across a cell membrane from a lower to a higher concentration. In active transport, particles move against the concentration gradient - and therefore require an input of energy from the cell.
The cellular membrane across which ion flow varies during auditory transduction is the hair cell membrane.
<h3>What is a cellular membrane?</h3>
A cellular membrane separates the interior of all cells from the outside environment.
Lipids of cell membranes include phospholipids composed of glycerol, fatty acids, phosphate, and a hydrophobic organic derivative such as choline or phosphoinositol.
Thus, hair cell membrane is the correct answer.

Answer: It depends on if your only talking about plants if so the answer is coal.
Explanation: The reason being because coal only forms from the compaction of dead plants whereas petroleum forms from compacted plants and animals.
Option (D) flagellated protist is correct.
The last common ancestor of all animals was probably a flagellated protist.
<h3>What is a Protist?</h3>
- Any eukaryotic organism that is not an animal, plant, or fungus is referred to as a protist.
- The absence of other eukaryotes means that protists do not constitute a natural group, or clade, even though it seems likely that they all descended from a common ancestor.
- Protozoa is another name for protists that resemble animals. Some are parasites as well.
- The four phyla that make up the Protozoa are flagellates, ciliates, spore-forming protists, and protists that resemble amoebas.
- Nuclear membranes surround the DNA of protists.
- Most protists are motile, or able to move, and many of them inhabit aquatic settings.
- Protists can reproduce sexually and/or asexually, and their life cycles are intricate.
- Protists consume, absorb, or produce food through photosynthesis.
