The management team at Electronics Galaxy is evaluating whether to have sales staff wear uniforms on the showroom floor. What should they consider about wearing uniforms ? a) How staff are dressed doesn't usually have much of an impact on customers. b) Uniforms can help customers identify members of the sales staff. Team morale usually suffers when uniforms are put in place . c) d) Uniforms can take away from each employee's individual personality.

Answers

Answer:

b) Uniforms can help customers identify members of the sales staff.

Explanation:

They should consider that uniforms can help customers identify members of the sales staff. The entire goal of a company/store is to make profits, and in order to do so, they need sales. Having the employees wear uniforms, instantly sets them apart from the rest of the customers in the store and makes them easy to find. This allows customers to find employees quickly and ask them for help. Being instantly available to customers in need drastically increases customer service levels and leads to increased customer satisfaction, which ultimately causes profits to increase as well.

3.Maja is about to be a senior, and it's time to choose the best college at which to study her chosen major. She schedules time each week to research one
potential college and list out the pros and cons for their academic programs.

Answer:

2. Fareed has just been diagnosed with type 2 diabetes, which he will battle for the rest of his life. He has consulted with a nutritionist for dietary advice and ordered multiple books on managing diabetes to learn how to keep his blood glucose levels in the healthy range.

Explanation:

Out of all the options, Fareed’s case is the longest-lasting issue. Drew won’t have to worry about the end of the school year for long, Maja won’t be in college forever, and while Nicoletta’s job may be important for a long time, she didn’t have an effective strategy to manage it. Fareed is the only one who fits having both a long-term challenge as well as a good way to handle it.

The scenario that describes a long-term challenge and an effective strategy to manage it is B. Fareed has just been diagnosed with type 2 diabetes, which he will battle for the rest of his life. He has consulted with a nutritionist for dietary advice and ordered multiple books on managing diabetes to learn how to keep his blood glucose levels in the healthy range.

How is the challenge illustrated?

From the given information, Fareed has just been diagnosed with type 2 diabetes, which he will battle for the rest of his life.

He then consulted with a nutritionist for dietary advice and ordered multiple books on managing diabetes to learn how to keep his blood glucose levels in the healthy range.

This showed how he coped with the challenge.

Answers

Answer:

a. Treatment team must agree on the dosage of medication at which to start prescribing

Explanation:

One of the most important points when determining a drug-based treatment is to determine the correct and efficient dosage that will improve the patient's situation and not cause further problems. The dosage of a drug must take into account the patient's weight, height, age and other factors related to the disease and the biological composition of the patient. If the dosage is applied incorrectly, it may not be effective in solving the patient's problem and may even intoxicate the patient.

a) The hamstring can be strengthened to reduce energy but can not advance in mass



b) The hamstring helps connect muscles and tendons from the lower and upper leg



c) The hamstring will be isolated and strengthened by squats



d) The hamstring can be easily pulled if not stretched properly

Answers

Answer:

except a rest of them are right

Hamstrings are the skeletal muscles that are voluntary and are present in the back of the thighs. The hamstring cannot be strengthened to reduce energy. Thus, option A is correct.

What is a hamstring?

A hamstring is a muscle and the part of the skeletal system that makes the muscles of the dorsal thigh region. They are voluntary and can be moved by the person's control.

The hamstrings are used for climbing, walking, running, and the squat exercise that involves the movement of the legs. They can be strengthened by squats.

Though they can be strengthened by squats they cannot reduce the energy and can get easily pulled if not stretched properly. They also connect the muscles and the tendons of the upper and lower leg.

Therefore, the hamstring cannot be strengthened by squats to reduce energy.
