Final answer:
C. 9.5 ml. The maximum volume of blood that can be safely collected from a healthy 950 gm (0.95 kg) macaw is 9.5 ml, which is 0.95% of its body weight in milliliters.
Step-by-step explanation:
The question asks about the maximum volume of blood that can be safely collected from a healthy 950 gm (0.95 kg) macaw. In veterinary practice, the general rule is that up to 1% of an animal's body weight can be collected without causing harm. For a macaw that weighs 0.95 kg, this means up to 0.95% of its body weight in milliliters can be safely collected. Since 1% of 0.95 kg is 0.0095 kg, and knowing that 1 kg equals 1000 ml, we multiply 0.0095 kg by 1000 ml/kg to find the volume in milliliters. This gives us a volume of 9.5 ml of blood that can be collected safely.
