Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

5. Anterior root
The correct answer is: A. A change in a cell's genetic material.
Mutations occur in DNA as a result of mistakes during the DNA replication (when repair mechanisms don’t fix it) or as the result of environmental factors (e.g. UV light). Mutations can have positive impact, by increasing the genetic variation or can have negative effect, causing the diseases or cancer.
Answer:
c. Bound to hemoglobin.
Explanation:
The oxygen is relatively insoluble in plasma. At normal atmospheric pressure, only 0,3% of oxygen dissolves. That why there are respiratory pigments that <u>elevate almost 70 times</u><u> the capacity to transport O₂ of blood</u>. The most common respiratory pigments are hemoglobin (in all vertebrates and some invertebrates) and hemocyanin (in mollusks and arthropods).

Answer - D. (The genetic code)
The genetic code is the nucleotide base sequence on DNA (with which information is encoded within genetic material). The nucleotide base sequence<span> codes for a sequence of amino acids, which are in turn used by living cells as the basic building blocks of proteins.</span>
