a. A shared ancestral character.
Explanation:
The condition of birds and mammals having four limbs is a shared ancestral character because the structure of the limbs are similar in both the cases.
The forelimbs of the bird are modified into wings to aid flying.The hind limbs are modified into feel and claws.
These are homologous structures to the hands and feet in mammals.
That means they have a common origin, and hence are shared ancestral character.

If there was a dramatic increase in skeletal muscle cell damage and apoptosis, I would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.
<h3>What does high CK-MB mean?</h3>
Elevated CKMB can be a sign of cardiac (heart muscle) damage or chronic kidney failure. At the onset of acute symptoms, after cardiac peaks, CKMB values are elevated after 3-6 peaks after 12-24 hours between 12-24 hours, values at 24-48-48.
With this information, we can conclude that if there was a dramatic increase in skeletal muscle cell damage and apoptosis, we would not expect a change in blood myoglobin and CK levels, because these markers are linked to cardiac muscle damage.
