Answer:
A variety of light bulbs contain mercury. Mercury is important in lighting since it helps to the efficiency and longevity of the bulbs. In general, fluorescent and other mercury-added bulbs are more energy efficient and last longer than incandescent and other comparable lights.
The choke's job is to create a very high voltage between the filaments at first (across the two ends of the tube light). The choke again delivers a low voltage after the gas in the tube is ionized. A choke is a wire coil. Mercury vapor fills fluorescent tubes and lights.

В. It is possible that your body weight is within the appropriate range, but your body composition is not.
Explanation:
The "BMI" or <em>"Body Mass Index" </em>is used in order to know whether the weight of a person is within the normal range. However, <em><u>it's not a real indicator for a person's body fat composition in the body.</u></em>
For example, a person within the normal weight may look healthy because his BMI is within the standard range; however, he may actually be fatty on the inside if his body composition will be checked. Another example are the weightlifters. They may seem heavy on the outside and their BMI are above the normal range; however, their body fat composition is low. So, this means they're healthier though they're overweight.
Plasma is the liquid component of blood, in which the red blood cells, white blood cells, and platelets are suspended. It constitutes more than half of the blood's volume and consists mostly of water that contains dissolved salts (electrolytes) and proteins.
Great question. Cardiovascular endurance is how efficiently you heart, blood vessels, and lungs to supply oxygen rich blood to working muscles during physical activity (aerobic activity like walking, running, cycling or playing a sport) for a prolonged period of time or for more than 90 seconds.
