were no telephones of any sort, much less wireless communication. In the trenches, on the other hand, invisibility was more important than identification. The analogy between human uses of camouflage and crypsis in animals is clear and direct. Humans have improved their own camouflage strategies ...
Animal cell cytoplasm is a gel-like material made of mostly water that fills the cells around the nucleus. It contains proteins and molecules that are particularly important for all cell health. The cytoplasm in an animal cell includes salts, sugars, amino acids, carbohydrates and nucleotides. Cy...
in part, chemical molecules calledneurotransmitters. Neurotransmitters released by neurons bind to receptors present on the body of receiving neurons, theircell membranes. Because neurons are negatively charged on the inside, when a neurotransmitter
castaneum. These phenomena concerning dopamine show an analogy to PD, which alters walking patterns49. In many animals, dopamine expression level relates to movement patterns, and a specific trajectory segment pattern of the L strain might be similarly deeply affected. To test this new hypothesis, ...
coli panE gene sequence, the Bacillus panE sequence was cloned by analogy. It was found that in B. subtilis, two homologs of the E. coli panE gene exist which were termed panE1 and panE2. Deletion analyses found that the panE1 gene is responsible for 90% of the pantothenic acid ...
analogy to eliciting depression in humans. In a comprehensive review, Gold proposed that symptoms of depressive disorders can result from an unbalanced adaptive response to ensure survival, in which a hypothalamus–pituitary–adrenal (HPA) axis dysfunction is the main effector. HPA axis response ...

and it may be impossible to completely isolate single gene effects. Researchers warn that one must be careful not to jump to a conclusion that they have found an '~aggression gene" or a "maternal gene" or an "anxiety gene." To use an engineering analogy, one would not conclude that they...
Sexual reproduction requires the generation of gametes, which are highly specialised for fertilisation. Female reproductive cells, oocytes, grow up to large sizes when they accumulate energy stocks and store proteins as well as mRNAs to enable rapid cell
In fact, the innovation of miRNA-like endogenous RNAs seems to have occurred multiple times also in diverse unicellular eukaryotes: despite functional analogy, there is no evidence for any homology between the plant miRNAs, animal miRNAs and the miRNAs reported for protozoa, including trypanosomes [...
