However, some cosmologists and physicists do attempt to investigate what could have occurred before the Big Bang, using such scenarios as the collision of membranes to give a cause for the Big Bang.

However, both cnidarians and ctenophores are more complex than sponges as they have: cells bound by inter-cell connections and carpet-like basement membranes ; muscles ; nervous systems ; and some have sensory organs.

However, this view neglects the fact that i ) both modern cyanobacteria and alpha-proteobacteria are Gram negative bacteria, which are surrounded by double membranes ; ii ) the outer membranes of the endosymbiotic organelles ( chloroplasts and mitochondria ) are very similar to those of these bacteria in their lipid and protein compositions.

However, as Witten was more skeptical about membranes than his colleagues, he opted for " M-theory " rather than " Membrane theory ".

However, this membrane may be tightly folded into cylindrical sheets called thylakoids, or bunched up into round vesicles called intracytoplasmic membranes.

However, modern bats and flying squirrels show considerable variation in the extent of their wing membranes and it is possible that, like these groups, different species of pterosaur had different wing designs.

However, generating plasma in air is too expensive and a feasible alternative is generating plasma between thin membranes instead.

However this stance is not entirely accepted as some human developmental biology literature refers to the " conceptus " and such medical literature refers to the " products of conception " as the post-implantation embryo and its surrounding membranes.

However, there have been documented cases of allergic reactions to PVP / povidone, particularly regarding subcutaneous ( applied under the skin ) use and situations where the PVP has come in contact with autologous serum ( internal blood fluids ) and mucous membranes.

However, the sclera themselves are not " icteric " ( stained with bile pigment ) but rather the conjunctival membranes that overlie them.

However, a study in 2007 indicated that LEEP appears to increase the risk of premature rupture of the membranes during subsequent pregnancies which may lead to preterm delivery.

However the validity of the detergent resistance methodology of membranes has recently been called into question due to ambiguities in the lipids and proteins recovered and the observation that they can also cause solid areas to form where there were none previously.

However some of the technology used in pumps and membranes still remains top secret, and some of the materials that were used remain subject to export controls, as a part of the continuing effort to control nuclear proliferation.

However, during evolution of the system, as objects are passed between membranes, the rules in other membranes will become active.

However, the receptor-independent process involves the diffusion of bitter, amphiphilic chemicals like quinine across the taste receptor cell membranes.

However, the SK2 immunoparticles were observed within intracellular membranes.

However, gas chromatography testing in 1984 revealed that sulfur-containing compounds, such as methanethiol, hydrogen sulfide ( rotten egg smell ) and dimethyl sulfide, were also < ref >

However, one researcher writes that this Cista (" kiste ") contained a golden mystical serpent, egg, a phallus and possibly also seeds sacred to Demeter.

However this chaos began to coalesce into a cosmic egg for eighteen thousand years.

However, mustard and garlic both have emulsion-producing properties and some variants ( such as Catalan Allioli ) omit the egg.

However, this does not mean there is no need for moisture throughout the first three weeks of life outside of the egg.

However, the egg was also said to have been a gift from Thoth, and laid by an ibis, the bird with which he was associated.

However, when an egg is removed from one woman, fertilized in vitro, and then placed in another woman, the resulting child inherits its mitochrondrial DNA from the woman in whose ovary the egg originated, and not the woman in whose uterus the child developed.

However, birth defects were more common if treatment included injecting a single sperm into an egg, which is done in many cases these days, especially if male infertility is involved.

However, they tend to flourish more in countries with warm, humid climates, because they require a certain amount of moisture in the air in order to undergo metamorphosis, and because low temperatures inhibit their development from egg to larva.

However, selective breeding practices may consider the size of the egg and correlate it with survival and early growth rate ( Gjedrem 1985 ).

However, he was effective in persuading others to provide him with the blood, tissue, and egg white samples which were the key to his work.

However, they were hard to obtain and produced unreliable egg viability.

However, Nick and Fetcher ends up arguing with each other over whether the chicken or the egg came first.

However, Microsoft had built an easter egg into the version 2 or " upgrade " Commodore Basic that proved its provenance: typing the ( obscure ) command would result in appearing on the screen.

However this creates an inconsistency ( paradox ) in which the egg has no origin.

However, the story behind the games remained the same: Tamagotchis are a small alien species that deposited an egg on Earth to see what life was like, and it is up to the player to raise the egg into an adult creature.

However, there are reports that indicate this species also was an egg layer.

However, if the egg whites are beaten too much, or if a tiny amount of fat is allowed to contaminate the mixture, then the proteins will not be able to form the correct molecular structure when cooked, and the meringue may collapse when cooked.

However, their happiness is crushed as the Sour Kangaroo and the Wickersham Brothers drag Horton back to the Jungle of Nool, and put him on trial for the crimes of " talking to a speck of dust and loitering on an egg ".
