Answer:

C. potassium oxalate for plato / edmentum

Explanation:

I took notes in the class and my notes say -

To prevent blood from clotting, toxicologists add anticoagulants to the blood sample. Anticoagulants such as potassium oxalate (30 mg/mL) is preferred over heparin or ethylenediaminetetraacetic acid (EDTA) because both heparin and EDTA interfere with the detection of certain chemicals, such as calcium, in the blood. If the blood is suspected of carbon monoxide poisoning, a layer of liquid paraffin is added over the blood sample. This layer prevents exposure to atmospheric oxygen.

What is meant by the genetic code being nearly universal?
Veseljchak [2.6K]

A lot of DNA is structural and doesn't pertain to any genetics while it only takes a small change to change something big. DNA mainly uses 4 different chemicals to change itself, not giving a lot of variety. Most animals share around 98% of the same dna with each other. Humans share 50% of their DNA with a banana. Pretty much everything shares the same double helix design as well. So a lot of genetic code looks similar.
