Carbohydrates are in place of simple sugars and complex carbs which either are quick energy or stored energy for performance. Without carbs, the body will shut down because you need sufficient energy to keep going. Carbs are what keeps you moving and functioning.
Answer
What is missing from the list is A. Select the most expensive PPE available
Explanation
The use of PPE in work activities which have been identified as hazardous is essential to both employers and employees because it is the responsibility of the employer to safeguard the health of workers through provision of proper working gear. When the hazard has been identified, employees should select PPE that properly fits, it should be the correct PPE according to the tasks to be done and provision of a list for the correct PPE can come in handy. Selecting the most expensive PPE available should not be the case.
Poor posture can lead to back pain by causing problems with your intervertebral discs and joints, as well as your muscles.
Poor posture can place stress on your spine that can lead to anatomical
changes in the spine such as shifting of discs and adjustments to the
natural curvature of the spine. These changes can ultimately cause back
pain due to the constriction of blood vessels and nerves, causing pain.
For example, standing or sitting in a position with your neck tilted too
far forward for prolonged periods of time (common when using a cell
phone) can add extra weight on the vertebra and strain the trapezius
muscles, which can result in a change to the natural curvature of the
spine. In other cases, such as sitting for long periods of time with
poor posture, extra weight from the upper body can be placed on
intervertebral discs of the lower back while they are unsupported. This
uneven distribution of weight can result in pain caused by disc bulging
in the spine and pinched nerves.
Additionally, with
prolonged poor posture, muscles can become tightened and overstretched,
leading to muscle fatigue and stiffness, causing pain. For example,
standing for long periods of time with your weight more on one foot than
the other can place extra pressure on one hip, which can overburden the
muscles in the lateral hip region, causing them to tighten, while the
muscles in the buttocks weaken. Over time, this will result in the
development of muscle imbalances in the pelvic area, resulting in muscle
strain in the lower back and causing pain. Similarly, a common poor
posture position in which a person is "stooped", or stands with their
pelvis tucked in and their back flat instead of naturally curved,
creates muscle imbalances and a misalignment of the spine resulting in
muscle fatigue and pain in the neck and back.
