Answer:
The answer is A) Homologous structures
Explanation:
Homologous Structures:
- Homologous structures are anatomical features in an organism that are structurally and functionally diverse but they originate from a single common ancestor.
- Homologous structures possess a similar basic internal structure but can have entirely different morphology and function.
- For example, the wings of a bat and a human's arm have the same internal structure but they have different functions.
- Vestigial structures are evolutionary remnants that no longer serve a purpose in modern forms or descendants of the original organism.
- Inherited and developmental are out of context in terms of evolutionary relationships.
Answer:
Yes, carbonic acid is the part of blood buffer system.
Explanation:
Carbonic acid is a part of blood buffer system which helps in regulating of pH of the blood. Hydronium ion is responsible for the increase in acidity of the blood. The carbonic acid dissociates into bicarbonate and hydrogen ion, this bicarbonate ions react with the hydronium ion and prevent the pH of the blood from decreasing so we can say that carbonic acid is an essential part of blood buffer system.
