In addition, paramecia were observed in P-KCM to swim mostly downwards (data not shown).
However, Penrose's association with Hameroff means such perspicuity is extended to paramecia. For Stapp, the non-unitary function can be supplied by the infinite (personal comm...).
Figures 3 and 4 illustrate the effect of bifenazate and indoxacarb on the evolution of the growth of paramecia. All measurements were performed during the exponential phase of growth.
Paramecia can be quite useful to have in a biology classroom.
On the other hand, the decoded genomes of single-celled organisms like yeast, paramecia, and giardia are much simpler than animal genomes.
Prior investigations into the possibility of either instrumental or classical conditioning in paramecia have reported both positive and negative findings, with some serious questions later raised about the possible lack of proper controls in some of the studies.
We drag along inside us the brains of reptiles, the tails of tadpoles, the DNA of fungi and mice; our cells are permuted paramecia; our salty blood is what's left of our birth in the sea.
A study of the genes underlying aging and consequent "programmed" death in the simplest unicellular eukaryotes, such as paramecia and yeast, all the way through human beings, shows that these genes are remarkably similar in every species.
HABITAT: Ponds, bags, and swamps around the world COMMON PREY: Water fleas, mosquito larvae, microorganisms (e.g., Paramecia), and tadpoles HOW IT LURES: Plant gives off a faint odor that attracts insects.
Cultures were kept at 9 [degrees] C and then exposed to 22 [degrees] C [+ or -] 0.5 [degrees] C in the European Space Agency (ESA) "Biorack incubator." Their experimental protocol involved using a plastic-bag culture apparatus to grow paramecia in 0.65 ml liquid medium samples.
Might the evolution of asymmetric modern sex from symmetric DNA exchange (like that practiced by paramecia) have been one special case of this emergence?
Wayne walked in off the street and knocked, and Bradruff came out onto the splintery porch in his knobby bare feet, his shirt a washed-out paisley with cream-colored paramecia swimming through a burgundy background.
