- B. Maintaining a sedentary lifestyle
- C. Regularly engaging in moderate exercise
- D. Smoking cigarettes
Correct answer: C
Rationale: The correct answer is C: Regularly engaging in moderate exercise. Exercise can benefit the lymphatic system by promoting circulation and the movement of lymph fluid throughout the body. This helps to remove toxins and waste products, improving overall lymphatic function. Consuming a high-sugar diet (A) can have a negative impact on the lymphatic system by increasing inflammation and impairing immune function. Maintaining a sedentary lifestyle (B) can lead to poor lymphatic circulation and fluid retention. Smoking cigarettes (D) is harmful to the lymphatic system and overall health, as it can impair immune function and increase inflammation.

- C. A group with similar functions but different origins
- D. A group descended from a common ancestor
Correct answer: D
Rationale: Rationale: In the context of classification, "monophyletic" refers to a group that includes a common ancestor and all of its descendants. This group shares a single evolutionary origin and forms a complete branch on a phylogenetic tree. Monophyletic groups are considered natural and valid taxonomic units because they reflect evolutionary relationships accurately. Option D is the correct choice as it accurately defines the term "monophyletic" in the context of classification.

It also helps to maintain a stable environment for the central nervous system by regulating pressure and removing waste products. Blood (option A) is not the fluid that directly surrounds the brain and spinal cord. Plasma (option C) is the liquid component of blood and is not specific to the central nervous system. Myelin (option D) is a fatty substance that forms a protective sheath around nerve fibers but is not the fluid surrounding the brain and spinal cord.
