1. Increase myoglobin: This is correct. Myoglobin is a protein in muscle tissue that binds oxygen. Diving mammals have higher levels of myoglobin, allowing them to store more oxygen in their muscles and stay underwater for longer periods.

2. Increase tolerance to hypercapnia: This is correct. Hypercapnia is a condition of having too much carbon dioxide (CO2) in the blood. Diving mammals can tolerate higher levels of CO2 in their blood, which allows them to hold their breath for extended periods.

3. Increase tolerance to acidosis: This is correct. Acidosis is a condition in which there is too much acid in the body fluids. Diving mammals have adaptations that allow them to better tolerate acidosis, which can occur during prolonged dives due to the build-up of CO2 and lactic acid.

4. Extreme bradycardia on diving: This is correct. Bradycardia is a slower than normal heart rate. Diving mammals exhibit extreme bradycardia when they dive, significantly reducing their heart rate to conserve oxygen.
