Correct Answer is B
Explanation
A. size of the sperm: While sperm size is relatively uniform, it is not the primary diagnostic factor for fertility.
B. number of sperm ejaculated: Sperm count is the most critical factor; if the count falls below a certain threshold (typically 20 million/mL), the statistical likelihood of fertilization drops significantly.
C. shape of the sperm: Morphology is important, but count (quantity) is generally considered the primary limiting factor.
D. motility of the sperm: Motility (swimming ability) is crucial, but it is often secondary to the total count in initial fertility assessments.
Correct Answer is B
Explanation
A. a constant state maintained by living and nonliving organisms: Nonliving organisms do not maintain homeostasis.
B. a state of relative constancy: Homeostasis is not a "fixed" point but a dynamic equilibrium where variables fluctuate within a narrow, healthy range.
C. adaptation to the external environment: This is a broader biological concept; homeostasis is specifically about maintaining the internal environment.
D. changes in body temperature: This is just one example of a homeostatic variable, not the definition of the concept itself.
