I’m pretty sure it’s c. (You were right lol)
2. When the left ventricle relaxes, the aortic valve closes and the mitral valve opens. This lets blood flow from the left atrium into the left ventricle.
4. Quickly shocking the heart with an automated external defibrillator (AED) can save a person's life after cardiac arrest. An AED is a portable, battery-operated device that a bystander can use. It checks the heart rhythm and can send an electric shock to the heart to try to restore a normal rhythm.
5. High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause: Chest pain, also called angina.
hope this helps :)

The answer is true. if you don't have body fat your body will not function correctly and you could get diseases easily and you won't live very long. Many may not know that our body fat helps our skin and hair, maintain a normal temperature just think if we were to skinny we would be freezing to death, and our body fat helps cushion our organs and tissues.<span />
Solution for the problem:
w = h / p
Where:
Wavelength = w
h = Planck's constant = 6.626e-34J*s
p = momentum = m * v
m = mass = 45.9g (1kg / 1000g) = .0459 kg
v = velocity = 66m/s
p = m * v = .0459 kg * 66m/s = 3.0294 N *s
w = h / p = (6.626e-34J*s) / 3.0294 N *s = 2.76e-34 m
