Answer:
D. helps maintain membrane fluidity
Explanation:
<span>For question 1: we know the vA=10.0 cm3 and the m=89.6g. Using the equation D = m/vA give us: D = 89.6/10 = 8.96 g/cm3. Answer is (C) 8.96 g / cm3.
For question 2: We know the vA=1.2 cm3 and the D=.6 g/cm3. Using the equation D = m/vA and rearranging for m gives us m = D*vA: m = .6 * 1.2 = .72 g. Answer is (D) .72 g.
For question 3: We know the D = 8 g/cm3 and the m = 600g. Using equation D = m/vA and rearranging for vA gives us vA = m / D: vA = 600 / 8 = 75 cm3. Answer is (A) 75 cm3.</span>
The part of the brain stem that regulates vital activities such as heartbeat,breathing and digestion is the<u> Medulla oblongata. </u>The bottom part of brain which regulate your breathing,heart rhythms,blood pressure and swallowing.
The respiratory center is located in the medulla oblongata and is involved in the minute-to-minute control of breathing.It's locate where the brain and spiral cord connect, it help in control vital processes like our heartbeat, breathing and blood pressure.
This also responsible for reflexes of the face and throat like - coughing,sneezing,gagging. It can lead to respiratory failure, loss of sensation, paralysis,it causes 'brain death" and person can not survive.
