Answer:
They were never alive
Explanation:
Abiotic refers to something that is and was never alive.
When an organism is exposed to a limited quantity of oxygen, the cell's mitochondria will stop cellular respiration involving the Krebs cycle and enter the process of fermentation to survive, it means <span>Fermentation must create a net gain of ATP.</span>
Answer:
A fusion protein can be sythesized to carry a specific tag, which is useful in identifying the proteins in various experiments. Fusion proteins with the FLAG epitope bind to specific anti-FLAG antibodies and carry this extra sequence: Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys. The bioteh company that sells anti-FLAG antibodies states that fusion proteins carrying the Flag epitope display the sequence on the surface of the protein. This is likely <u>A short hydrophilic 8-amino acid peptide</u> because<u> of its hydrophilic nature</u> of the eight residues are <u>Likely to be located on the surface of the fusion protein</u>, making FLAG highly <u>Specific and easily accessible for cleavage by enterokinase </u> and likely to interact<u> with other epitope and domains</u> Al with water.
Explanation:
FLAG, a short hydrophilic peptide consisting of 8 amino acids have been widely used as a fusion tag for purification and detection of a wide variety of recombinant proteins. the 3× FLAG system is an improvement upon the original system by fusing 3 tandem FLAG epitopes (22amino acids). detection of fusion protein containing 3× FLAG is enhanced up to 200 times more than any other systems.
Your nose and your mouth are both a portal of entry into your body. If you cover one and not the other it defeats the purpose because Bacteria can still enter the system. They are both part of your respiratory system.
Answer:
Nitrogen thet cannot be used by organisms. C.
Explanation:
Free nitrogen is simply molecular nitrogen (N2). Nitrogen, in its molecular form, consists of two nitrogen atoms bound together with a tripple bond. Because it is very stable, N2 is typically nonreactive, and takes a lot of energy to break them apart. Among these are the amino acids necessary for life to begin and which are the building blocks DNA is made from. Basically, any nitrogen that is in an organic compound is considered “fixed” nitrogen and N2 is considered to be “free” nitrogen
