Final answer:
Marbling refers to the specks of fat interspersed within muscle, which are influenced by hormones and genetics and can affect meat quality. The distribution of fat in humans varies by gender and changes over time. The BMI is a commonly used tool for assessing fat levels but may not be accurate for all individuals. Option number b is correct.
Step-by-step explanation:
The specks of fat interspersed in the muscle are referred to as marbling. Marbling is the term used to describe the fine, thread-like flecks of fat within lean muscle tissues. These small flecks can add flavor and tenderness to the meat and are sought after in certain cuts of beef for culinary purposes.
Fat distribution within the body, including the deposition of adipose tissue in the hypodermis, is influenced by various factors such as hormones (testosterone, estrogen, insulin, glucagon, leptin, etc.) and genetics. It is important to note that fat distribution and accumulation can change as an individual matures and ages. Moreover, different genders exhibit tendencies to accumulate fat in different body areas, illustrating the complexity of biological adipose deposition.
The Body Mass Index (BMI) is often associated with fat measurement. However, this index is based on a formula that relates mass and height and may not accurately reflect health status, particularly in highly fit individuals. Outside of health concerns, the fat storage and adipose tissue in the hypodermis serve as energy reserves, insulate the body, and act as a protection mechanism.
