What purpose would the sand serve?
mihalych1998 [28]

Sand is a granular material composed of finely divided rockand mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.[1]

The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastalsettings is silica (silicon dioxide, or SiO2), usually in the form of quartz. The second most common type of sand is calcium carbonate, for example, aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean.

Sand is a non-renewable resource over human timescales, and sand suitable for making concrete is in high demand.[2] Desert sand, although plentiful, is not suitable for concrete, and 50 billion tons of beach sand and fossil sand is needed each year for construction.

the nurse completes dietary teaching with a client who has chronic kidney failure. the nurse determines more teaching is needed
VashaNatasha [74]

Answer:

The options

"I will eat more oranges and other foods with vitamin C."

"I should increase dairy products in my diet."

"I should add protein powder to my fruit smoothies."

The CORRECT ANSWER IS

"I will eat more oranges and other foods with vitamin C."

Explanation:

"I will eat more oranges and other foods with vitamin C."

Citrus fruits are rich in potassium and should be stayed away from, since kidneys find it difficult to remove the excess potassium. Examples of foods that are rich in potassium are dried fruits, avocado, tomato, potatoes, and bananas. This statement indicates that additional teaching is needed.

In kidney failure, the client stands a higer chance for hyperkalemia, hypernatremia, and hyperphosphatemia.

Potassium, is found in large amounts in citrus fruits and dried fruits, and there's need to take these fruits with caution.

Phosphorus is limited due to the important balance of potassium electrolyte with calcium. Protein is inhibited as the failure to remove uric acid, which is produced during protein metabolism, via the kidneys. Sodium, obtained in foods, is also restrained to avoid fluid overload and edema.

What are two advantages of using the SI system?

 1. No conversions. The greatest advantage of SI is that it has only one<span> unit for each quantity ( a type of measurement). This means that it is never necessary to convert from one unit to another (within the system) and there are no conversion factors for students to memorize.

2. </span><span>No fractions. SI uses decimals exclusively, eliminating clumsy fractions and mixed numbers.</span>
