Correct Answer: C

Rationale: Phospholipids are the correct answer because they consist of long hydrocarbon chains and form the lipid bilayer, which is the fundamental structure of cell membranes. Their amphipathic nature (having both hydrophilic and hydrophobic regions) allows them to create a barrier that separates the cell's internal environment from the external environment, making them essential for cell integrity and function.

Correct Answer: A

Rationale: Tremor, bradykinesia, and muscle rigidity are the correct answers because these are the cardinal features of Parkinsonism. Bradykinesia refers to slowness of movement, rigidity refers to increased muscle tone, and tremor is often present at rest. These symptoms result from the degeneration of dopaminergic neurons in the substantia nigra.

Correct Answer: C

Rationale: Anterior horn of the spinal cord is the correct answer because fibrillations and fasciculations are spontaneous muscle contractions that occur due to the degeneration of lower motor neurons located in the anterior horn. These contractions are a sign of denervation and are commonly seen in conditions like amyotrophic lateral sclerosis (ALS).
