Answer:
A. Bacterial species use a limited number of nutrient sources.
Explanation:
There are two classes of nutrients that are indispensable to bacteria: macronutrients (carbon, oxygen, nitrogen, sulfur, phosphorus and hydrogen) and micronutrients (iron, zinc, manganese, calcium, potassium, sodium, copper, chlorine, cobalt, molybdenum, selenium, magnesium, among many others). But it takes more than the nutrients for them to feed, it takes the metabolism, because it is through it that they transform what they have into food.
The absorption of nutrients to carry out the metabolism only occurs because there are growth factors (environmental) that influence the development of the bacteria. Some examples of these factors are: light, temperature, pH, oxygen and osmotic pressure. Each organism has an optimal growth temperature, or a favorable pH to successfully carry out its metabolism. This will vary from species to species.
The question is incomplete, the complete question is:
A client with myasthenia gravis improves and is discharged from the hospital. The discharge medications include pyridostigmine bromide (Mestinon) 10 mg every six hours. The nurse evaluates that the drug regimen is understood when the client says, "I should:
1
Take the medication on an empty stomach."
2
Set an alarm so I take the medication on time."
3
Take my pulse rate before taking the medication."
4
Monitor for an increase in blood pressure after taking the medication."
Answer:
The correct answer is statement 2.
Explanation:
Pyridostigmine refers to an essential drug, which must be consumed on time, as a late or missed dose can lead to extreme neuromuscular and respiratory consequences or even death. Pyridostigmine should be consumed with a small concentration of food in order to inhibit gastric irritation.
It is not essential to take the pulse rate prior to taking the medication. Pyridostigmine may result in hypotension, however, not hypertension, which is not an indication of cholinergic crisis.

Answer:
The development of refrigeration and frozen-food technology has benefited society in the following ways.
1) Refrigerator helps the people to protect the food substance from the infection of microorganisms such as bacteria and fungi.
2) Refrigerator helps in increasing the shelf life of many food materials. Some food substance have very short shelf life which can be increased by placing in the refrigerator.
Chicken sausages, nuggets and meat boll are the products that developed because of frozen -food technology.
