Blood proteins are similar in

Options

A. fishes and reptiles
B. amphibians and birds
C. amphibians and mammals
D. birds and mammals

Answer

**Step-by-Step Solution:**

1. **Understanding Blood Proteins:**
- Blood proteins are essential components found in the blood, such as albumin and globulin. They play crucial roles in various physiological functions.

2. **Functions of Blood Proteins:**
- Blood proteins are involved in transporting metabolites and metals throughout the bloodstream.
- They also play a significant role in the immune system, helping to defend the body against pathogens.

3. **Analyzing the Options:**
- The question provides four options regarding which groups of animals have similar blood proteins:
- A) Fishes and reptiles
- B) Amphibians and birds
- C) Amphibians and mammals
- D) Birds and mammals

4. **Evaluating Each Option:**
- **Option A (Fishes and reptiles):** Blood proteins differ significantly between these groups due to evolutionary divergence.
- **Option B (Amphibians and birds):** Research indicates that blood proteins in these two groups show similarities.
- **Option C (Amphibians and mammals):** Blood proteins in these groups are not the same, as mammals have evolved distinct blood protein profiles.
- **Option D (Birds and mammals):** Similar to option C, birds and mammals have different blood protein compositions.

5. **Conclusion:**
- Based on the analysis, the correct answer is **B) Amphibians and birds**, as they share similarities in their blood protein composition.
