Answer:
The minimum mass of dissolved cholesterol that the new system must be able to detect is 0.43 milligrams.
Note: The question is incomplete. The complete question is:
<em>GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect borderline high levels of dissolved cholesterol (170, to 200. mg/dL), using a blood sample that is as small as 250 μL Calculate the minimum mass in milligrams of cholesterol that the new system must be able to detect Be sure your answer has the correct number of significant digits.</em>
Explanation:
Range of the equipment to detect cholesterol in blood = 170.0 to 200.0 mg/dL
Minimum amount of cholesterol that can be detected by instrument = 170 mg/dL
Volume of blood sample = 250 <em>μ</em>L= 0.0025 dL (1 dL = 100000 <em>μL)</em>
Amount of dissolved cholesterol in 250 <em>μL</em> sample of blood =
170 mg/dL * 0.0025 dL = 0.425 mg
The minimum mass of cholesterol that the new system must be able to detect is 0.43 milligrams.

Answer:
An element is a material that consists of a single type of atom. which Each atom type contains the same number of protons. the Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
Explanation:
Always melt chocolate slowly, at a low temperature. The melting point of chocolate is between 86 degrees F. (30 degrees C.) and 90 degrees F.
Answer:
If garbage is dumped into the ocean, the oxygen in the water could be depleted. This results in poor health for marine life due to lack of oxygen. Animals such as seals, dolphins, penguins, sharks, whales, and herring could all die. Bottles and other plastics including bags can suffocate or choke sea creatures.
