In principle it should be possible, providing that you have the suitable enzymes, however one of the possible problems I foresee with such a setup is saponification:
Saponification is a process that involves conversion of fat or oil into soap and alcohol by the action of heat in the presence of aqueous alkali (e.g. NaOH). [...] Vegetable oils and animal ...
Not the same way. The acid is not what is actually doing most of the digesting of the food; it is an enzyme called pepsin. The reason the stomach is acidic is pepsin works optimally at a Ph of 2. According to Wikipedia, pepsin is "inactive at pH 6.5 and above", meaning that a base would be detrimental to digestion.
Oh but they can breed. They just have the same problem as modern day bulldogs: they just don't have a shape that favours a tight fit.
Or do you really picture a couple of these ones coupling?
You've never seen sex capable chimeras for the same reason that Mosanto's crops are sterile: there is actual profit to be made if your customers always have to come ...
Each time you make a chimera you are creating a new species
Some simple people think that for making a basic sphinx you only need to mix a human and a lion. That somehow you mix both and the result will always be a sphinx. Those that hold such views reveal their uttermost ignorance of the art of chimeracraftship. For it is clear for even the most dumb, that ...
They can breed. They just don't breed true.
Start with Mendel and his peas. There is more going on in the genome that is apparent in the phenotype. When you cross 2 animals apparently the same, you will get some traits in the offspring that were present in neither parent.
This is ...
The magic that binds the Chimera together also prevents them from breeding. The original component animals weren’t sterile, but the resulting creature is (because of the transmutation process).
If you want a slightly more involved (and messier) reason:
The magic that binds the Chimera together is linked to their life force. When creatures ...
The DNA of the creatures remains separate. While the immune response of each creature will no longer murder these alternative DNA cells (strongest traits of the parents!) It also means that when creating sperm cells the DNA remains separate.
Example, in the case of 3 creatures being merged, the sperm created would consist for 33% out of each ...
The Gods determined that taboos must be broken.
Just as in Greek mythology, the Sphinx - Σφίγξ- was most often depicted as female with a human head, a lion (or other great cat) and wings:
treacherous and merciless
In Egyptian mythology it would have been without wings and male.
Such archetypal creatures have been common in mythologies of the world ...
There is blood in the milk.
Milk comes from glands. Glands have blood vessels. There are various reasons a blood vessel might burst and bleed more or less blood into the milk.
Blood is red from the protein, hemoglobin. Hemoglobin has a molecule called a "heme" which has the metal iron in it. When the iron is oxygenated, it becomes red. When the iron is deoxygenated, it becomes darker red.
I would say the animal would probably eat food very high in iron, be it red meat, or spinach (a lot of leafy greens have high iron ...
The creature in question eats foods rich in natural red dyes
Most of these plants require boiling to get the dye, but the acid bath of digestion is enough to get to that point. The problem, of course, is that the mammal would need to eat this stuff almost exclusively (or at least a whole lot of it). But methinks it would create the color you're looking ...
Love, and milk.
Many hormones are evolutionarily very ancient. One is oxytocin.
In the brain, oxytocin acts as a chemical messenger and has been shown
to be important in human behaviours including sexual arousal,
recognition, trust, anxiety and mother–infant bonding. As a result,
oxytocin has been ...
If your human and octopus are connected by something like a placenta, hormones could cross.
I see in your comment you are having the octopus buddy breathe with your villain. Not super crazy - the human can avail himself of the octopus gill's ability to extract oxygen from water. That is similar to what the placenta makes possible: the mother breathes for ...
The short answer is no; if you're extracting the oxygen from the blood of an octopus of any size or age, then you don't have to worry about hormones coming along for the ride. How can I be so sure of that? Well, we've been extracting medical grade pure oxygen from the atmosphere for some time for use in a range of applications including the treatment of most ...
The main effect I could see is the human suffering a severe allergic reaction as the alien proteins entered the bloodstream and then into the body. Not a itchy skin rash type reaction but more like anaphylactic shock or major organs shutting down type of reaction.
It is tricky enough doing blood transfusions between human beings unless you have carefully ...
The guardian can't survive.
If we only stop/sufficiently slow down chemical reactions but leave other physical processes untouched the following things will be a problem:
Lots of tiny parts (i.e. blood cells) in the body are in physical motion all the time. Without chemical reactions they can't be properly steered or maintained and will ...
Reality Check time.
In my world there is an old human guarding something of great significance.
Presumably the least assumption we can make is that this guard was put there with the intent of surviving by whoever put them there. So the first problem is that we would assume the system was intended to keep them alive and failed for some reason.
If, BYW, ...
Unfortunately slowing his chemical reactions isn't enough. Even assuming you slow all the chemical reactions in the room such that the torches burst into life when someone walks in (and nothing eats him).
Stopping the primary processes of life isn't enough, there are physical processes that'll "kill" a statue given enough time. Remember that those ...
Should all else fail, you can turn to a biochemistry solution for this one.
Cells have transport/channel proteins in their walls, that let only specific molecular or atomic ions pass.
The ability to let only specific particles pass is related to the energetic structure of the binding part of a channel protein, which is 'gauged' onto the energetic structure ...
I'm gonna go out on a limb here and say no (and get away with it because you haven't asked for hard science!)
$N_2$ is smaller and lighter than $CO_2$, and neither are polar. There's no trivial way to make a membrane that would let the larger molecule through and reject the smaller. Technology does exist to filter nitrogen (used in oxygen concentrators) and ...
Depending on how deep you go, Nitrogen is not your only problem. Once you get below about 60m of depth, oxygen toxicity also kicks in and CO2 poisoning is also something divers really have to worry about. The way they deal with all of this is special air mixes that contain percentages of inert gas to reduce the amount of oxygen and nitrogen they breathe in, ...
You could do this with a cross between a SCUBA system and an oxygen concentrator.
Oxygen concentrators typically use pressure swing adsorption (PSA)
technology and are used very widely for oxygen provision in healthcare
applications, especially where liquid or pressurized oxygen is too
dangerous or ...
