Answer:

The correct answer is option B.  "micropipette".

Explanation:

Micropipette is an essential laboratory apparatus to transfer a defined amount of liquid from one reservoir to another. The micropipettes are highly accurate and precise with different ranges of volumes to fit to the operator necessities. A specialized technique, such as the polymerase chain reaction that Ricardo is performing, requires the use of micropipettes to measure and transfer microliters of solutions.

zalisa [80]

Laboratory tests and clinical procedures include:

  • The blood glucose test and the glycosylated hemoglobin test are tests to identify diabetes and prediabetes (A1c).
  • A glucose tolerance test may be administered to you if you're expecting to check for gestational diabetes.
  • Your thyroid's functionality can be determined by a number of tests, chief among them a TSH measurement.
  • Other examinations can evaluate parathyroid problems.
  • Female hormonal problems can be identified with the aid of luteinizing hormone (LH) and follicle stimulating hormone (FSH) blood tests.
  • Male hormonal problems can be discovered with tests for total testosterone.
  • Other blood tests measure hormone levels that have an impact on numerous systems, including cortisol, 17-hydroxyprogesterone, DHEA-sulfate, ACTH, aldosterone, vitamin D, PTH, prolactin, and other estrogen analogues.
  • Thyroglobulin (Tg) tests can be used to track thyroid malignancy.

Why is it incorrect to say the insulation 'keeps out the cold'
Sonja [21]
Because technically there is no such thing as cold
all that exists is heat
this is because heat is the rapid movement of particles, made by friction (to understand why you must delve into physics and some chemistry)
so, when you feel cold, it's really the absence of heat
so instead of "keeping the cold out", which makes no sense at all scientifically, insulation keeps the heat in.

as a side note
the feeling of cold is produced when you come in contact with an object (yes, air counts) that has less heat, or energy, than you do, You feel cold because heat (energy) from your body is being transferred to the environment. This ABSENCE OF HEAT in your body is why you feel cold
