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:
DNA: DNA stores biological information in sequences of four bases of nucleic acid — adenine (A), thymine (T), cytosine (C) and guanine (G) — which are strung along ribbons of sugar- phosphate molecules in the shape of a double helix. ... Taken as a whole, this package of DNA serves as its owner's complete genetic blueprint.
Explanation:
an organisms role within its environment is its this is for both the top one and bottom one : A community includes all the populations of the area. The community and the abiotic factors make up the ecosystem. An organism lives in its habitat within a community. The role or job of an organism within a community is its niche.

Answer:
The correct answer is option d. "The various substituents on the tetrapyrrole ring alter the absorption properties of the pigments".
Explanation:
In chlorophyll and bacteriochlorophyll pigment molecules absorb light energy for photosynthesis at different spectrums. The means at which absorption spectrum is controlled is by the fact that the various substituents on the tetrapyrrole ring alter the absorption properties of the pigments. The tetrapyrrole ring has a a magnesium atom at its center, which in conjuction acts as an antenna for light's absorption.
On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts (in eukaryotic cells). Blue-green algae (which are prokaryotic) carry-out the photosythesis reactions in the cytoplasm.
So all of the above
