Final answer:
The sentence contains one independent clause describing how someone walks and includes descriptive phrases, but lacks any dependent clauses or a conjunction joining two independent clauses.
Step-by-step explanation:
The sentence "He walks with his heel down with a varus tendency in the ankle but with no severe problem." includes one independent clause and no dependent clauses or conjunctions joining two independent clauses. The independent clause can be split into the main subject pronoun 'He' and the main intransitive verb 'walk.' There is no subordinating conjunction indicating a dependent clause, and the phrase 'with his heel down' serves as an adverbial modifier describing the manner of walking.
Additionally, the phrase 'with a varus tendency in the ankle' further describes the walking, and 'but with no severe problem' adds additional information but does not form a dependent clause since it does not contain a subject and verb combination with dependent status.
