The alarm reaction to danger that is triggered by anxiety primarily involves the sympathetic nervous system

The sympathetic nervous system (SNS) primarily stimulates many parts of the body for action in times of danger or emergency situations.
During this process, a hormone known as adrenaline (the emergency hormone) would be released, and effects such as sweating, increased heartbeat, raised blood pressure will follow.

The person is 30 years old! Here's how you solve it:
A = .8 (220-a)
152 = .8 (220-a)
152 = 176 - .8a
.8a = 24
a = 30
Hope this helps!
Answer:
b) Insoluble in water
Explanation:
Lipids or fats are water-insoluble organic molecules and soluble in certain organic substances such as alcohol, ether and acetone.
Lipids can be found in plant and animal foods and should be consumed in a balanced manner. These molecules have functions such as energy reserve, thermal insulation and vitamin absorption.
Lipids are esters, meaning they are composed of one acid molecule (fatty acid) and one alcohol molecule (glycerol or other). They are insoluble in water because their molecules are nonpolar, that is, they have no electric charge and therefore have no affinity for the polar molecules of water.
