Answer:
The nasal cavity and its mucous have two primary purposes in the process of breathing: Role as a Passage for Inhaled Air: During inhalation, air enters through the nostrils and passes via the nasal cavity into the pharynx and larynx, the next sections in the respiratory tract, to eventually reach the lungs.

Answer:
b. multicellular fungus
Explanation:
In a recent study, it was discovered that there was a genetic relationship between multicellular organisms like protozoa and animals and fungi have a common ancestor as their ancestors had contact about 1.1 billion years ago.
Therefore, the organism that was most likely the most recent common ancestor of all animals is multicellular fungus
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working. pH: Each enzyme has an optimum pH range. ... Extreme pH values can cause enzymes to denature.
Answer:
I am pretty sure that the answer is A.
Explanation:
Protein kinases regulate the cell cycle by giving the "go-ahead" or "stop" signal at checkpoints in the cycle. A mutation/disruption in the protein kinases can result in it not doing its job properly. As a result, it can give the 'go-ahead' signal to all cells (mutated or not) to continue through the cell cycle. A distrupted kinase will infleunce the enviornment for a cancer cell as the cancer cell can continue to divide continuously.
I do not think the answer is D because G-couped receptirs are not involed in the regulation of the cell cycle. Additionally, I do not think the answer is C since the production of cAMP (a secondary messgenger amplifies transduction signals; this doesn't have anything to do with cancer?) Finally, between A and B I know that a direct result of cancer is due to a distruption in either protien kinases or growth factors (not in the answer choices). Since one of the factors that leads to cancer is present in answer choice A, I think that is the one. However, this is just my reasoning, I am not 100% sure!
