Answer:
All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.
Answer:
collecting duct, renal pyramid
Explanation:
The collecting duct receives the filtrate from the DCTs of several nephrons and funnels it toward the renal pyramid.
Answer: D) Any protein made from mutated DNA will not function properly
Explanation: During replication, DNA polymerase double-checks and removes every newly added wrong nucleotide. This is to maintain high fidelity because if a mutated DNA is synthesized during replication, it will also lead to synthesis of an RNA with an altered nucleotide sequence during transcription and consequently lead to the synthesis of a protein that will not function well during translation.
