The most solid connective tissue is__________; the most fluid connective tissue is ________.

A. ceruminous:Ceruminous glands are modified sweat glands located in the ear canal that produce earwax (cerumen), not scalp oil.

B. sebaceous:Sebaceous glands are associated with hair follicles and secrete sebum, an oily substance that lubricates the hair and skin, helping to maintain moisture and provide a protective barrier.

C. apocrine sweat:Apocrine sweat glands are found in specific areas such as the axillae and groin. They secrete a thicker, milky sweat, usually in response to stress or hormonal signals, and do not produce scalp oil.

D. mammary:Mammary glands are specialized sweat glands that produce milk. They are not involved in producing scalp oil.

E. merocrine sweat:Merocrine (eccrine) sweat glands are widely distributed and secrete a watery sweat primarily for thermoregulation, not for lubricating hair or skin.

A. anaerobic:Anaerobic respiration, such as glycolysis, occurs without oxygen and produces only a small amount of ATP, typically 2 ATP per glucose molecule. It provides quick energy but is not the main source of ATP generation in cells.

B. anabolic:Anabolic reactions involve building larger molecules from smaller ones, such as protein or glycogen synthesis. These processes consume energy rather than produce it, so they do not contribute to ATP generation.

C. aerobic:Aerobic respiration occurs in the presence of oxygen and includes the Krebs cycle and electron transport chain. This pathway produces the majority of ATP, yielding around 34–36 ATP molecules per glucose, making it the primary energy source.

D. None of the Correct answers are correct:This option does not apply because aerobic respiration is the well-established pathway responsible for generating most of the cell’s ATP.
