Answer:
The options are
A) gustatory complex
B) olfactory bulb
C) occipital lobe
D) posterior pituitary gland
The answer is B) olfactory bulb
Explanation:
The olfactory bulb is found in the forebrain and has a rich amount of neurons. It helps in the process of olfaction which means the sense of smell in organisms.
Most of the chemosensory neurons arising in the nasal cavity( nose) which is the organ used for smelling have axonal projections that terminate in the Olfactory bulbs.
The most important idea is that the genetic material of any organism must be able to accurately replicate itself at least every generation (or for multicellular organisms at each cell division).
Base pairing (A-T or U and C-G)allows DNA and RNA (eg in polio virus, see Wikipedia page on RNA dependent RNA polymerase) to create a copy of themselves, when the appropriate enzymes are present. Proteins have no way of making a copy of themselves.
Stability is probably the main reason DNA is the most common genetic material. DNA has no enzymatic activity and was probably selected for to maintain the integrity of the genetic material (rather than having to perform a function for the cell/virus, during which it may be destroyed). The double helix structure also protects its integrity, and proofreading enzymes have also evolved which correct most of the mistakes made at DNA replication. RNA viruses don't have this mechanism- which could be said to be an advantage (as they can rapidly change and therefore avoid their hosts' immune systems), however in non-parasitic organisms most mutations in a gene would lead to a loss of an essential function and the extinction of that genome.
I don't think either of these reasons are relevant, but I think the main reasons retroviruses convert their RNA to DNA are so they can use the host cell's replication machinery (this was they do not need to encode as many genes), and secondly they need avoid the antiviral mechanisms of the cell, which would destroy any double stranded RNA molecules found (even if the virus was single stranded, dsRNA would have to be produced at replication).
The LPN/LVN must be suspecting post operative atelectasis.
Explanation:
Post operative fever in a patient is a common symptom but rales are mostly associated with blocking of air passage. And this blocking of air passage is a common symptom of atelectasis.
Moreover, atelectasis is common in patients who have undergone major surgeries under anesthesia.
Anesthesia changes the rate of lung intake so resulting in collapse of few alveoli.
Thus, it is more probable for the nurse to suspect the development of atelectasis.
Answer: well i basically agree with u what "smart" invtented school anyway
Explanation:
Yes,because birds know what birdseeds they eat so when they see another color of bird seeds they know that's a different type of seed compared to one they eat.
