Final answer:
The maximum volume of blood that can be safely collected from a healthy 950 gm macaw is less than 0.76 ml, making option B (0.95 ml) the closest correct answer.
Step-by-step explanation:
The question deals with determining the maximum volume of blood that can be safely collected from a healthy 950 gm (0.95 kg) macaw. The calculation is based on veterinary practices and guidelines for blood collection, which state that dogs, for example, have approximately 80-90 ml of blood per kg body weight. Although macaws are not dogs, if we use a similar approach as a reference, we can consider a proportionate amount of blood volume relative to body weight. Using the lower end of the scale, 80 ml per kg would equate to 0.95 kg x 80 ml/kg, which is 76 ml. To ensure safety, the volume collected should be much less than this total volume. Keeping in mind the safety of the animal and common practice, the volume of blood that is collected typically does not exceed 1% of the animal's total blood volume to avoid causing harm or significant stress to the animal. Therefore, for a 950 gm macaw, the maximum safe volume would be less than 0.76 ml, making option B (0.95 ml) the closest correct answer.
