Which function of a sperm would be eliminated if a sperm lacked an acrosome?

A. Pons: The pons is involved in regulating the rate and depth of breathing but is not the primary site affected by pyrogens for temperature regulation.

B. Cerebral cortex: The cerebral cortex is responsible for higher-order functions like reasoning and sensory perception but does not directly regulate body temperature in response to pyrogens.

C. Hypothalamus: The hypothalamus acts as the body’s thermostat and is directly affected by pyrogens, leading to the elevation of body temperature (fever) as part of the immune response.

D. Amygdala: The amygdala is primarily involved in emotion regulation and does not play a direct role in temperature regulation.

A. Marrow: The hollow spaces within long bones contain bone marrow, which is responsible for the production of blood cells.

B. Natural killer cells: Natural killer cells are a type of lymphocyte found in the bloodstream and tissues but not directly within the hollow spaces of bones.

C. Enzymes: Enzymes are not found specifically in the hollow spaces of long bones; they are present throughout the body and are involved in metabolic processes.

D. Plasma cells: Plasma cells are derived from B cells and are primarily located in lymphatic tissue and bone marrow but do not fill the hollow spaces of long bones.
