If the blood specimen from a dermal puncture is clotted before being mixed with the anticoagulant in the micro collection container, it will not be suitable for testing.
<h3>Why clotted blood cannot be used for testing?</h3>
In order to stop the loss of blood from damaged blood arteries, tissues, or organs, blood coagulation is a process where circulating components in the blood system are transformed into a gel with insoluble properties. The body creates a blood clot out of fibrin and platelets (thrombocytes) when a blood vessel (a vein or an artery) is wounded in order to stop further blood loss. Blood clots can still develop in the body even when no blood vessels are damaged. An embolus is a clot or a portion of a clot that separates and starts to move around the body.
Clotting has a negative impact on our automated hematology analyzer and unpredictably invalidates cell counts resulting in errors while testing.

Answer:
<u>c. Sucrose and glucose</u>
Explanation:
The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.
Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.
Answer:
inside
Explanation:
osmosis is where water moves from high water conservation(outside of the cell) to a low water concentration(inside the cell) through the memebrane.
Answer:
DNA is the genetic information used to make proteins, and it contains the hereditary traits of organisms. There are two types of DNA: mitochondrial DNA, which you can only get from your mother, and nuclear DNA, which is a combination of both your ancestors' DNA.
Explanation:
Answer:
Anther
Explanation:
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther.
Anther: The part of the stamen where pollen is produced.
Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.
