Explanation:
Answer:
D) anatomical features
Explanation:
The molecular systematics uses the data on the molecular structures to establish evolutionary relationships between the organisms. Techniques of DNA, RNA, and amino acid sequencing are used to compare the macromolecules of organisms. These studies provide information about the degree of relatedness among organisms. The closely related species share a higher degree of similarities in the sequences of these macromolecules. However, this branch of science does not include information about the anatomical and structural features to establish evolutionary relationships.
Answer:
Option C, Homeostasis
Explanation:
Homeostasis is a mechanism through which body maintain its state of stability/equilibrium. Thermoregulation is one of the mechanism of homeostasis by which body maintain its internal temperature. The average human body temperature is 98°F (37°C). When the external temperature increases, the body sweats or vassolidate to maintain the stable temperature.
When the external temperature decreases, the body undergo vasoconstriction or thermogenesis to main its average temperature.
Hence, option C is correct
