Answer:
These mice have lack of hormones that regulates the concentration of glucose in the body.
Explanation:
The body of these mice produced less or no adrenaline hormone that is responsible for the increase of glucose in the blood due to which blood glucose drops dangerously. If these mice has that adrenaline hormone and it works properly so blood glucose does not drops dangerously in these mice so we can say that lack of adrenaline hormone is responsible for this problem.
Answer:
Presence of papillary muscles
Explanation:
- Papillary muscles are structural components of the ventricles.
- They are attached to the cusps of the mitral and tricuspid valves through connective tissue strings known as the cordinae tendeneae (heart strings).
- These muscles prevent the prolaspse of these valves during ventricular systole.
- Although they differ in number i.e. two in left and three in right ventricle, papillary muscles are present in both ventricles.
