poten-, pot-, poss-, -potent, -potence, -potency, -potential +

The ability, shown by many, if not all, living cells, to form all of the types of tissues that constitute mature organisms.

This may be achieved, even if the cells have completely differentiated, provided that the appropriate balance of nutrients and hormones is given.

The best example of this phenomenon is the formation of adventitious embryos in carrot tissue cultures. Totipotency demonstrates that each cell retains the full genetic potential of the species.

1. With reference to a cell or part, having the potential for developing in various specialized ways in response to external or internal stimuli.
2. The ability of a cell to differentiate into a complete organism or into any other related cell.
3. The ability of a cell, such as an egg, to give rise to unlike cells and thus to develop into or generate a new organism or part.

1. A reference to cells that are capable of developing into only one type of cell or tissue.
2. Referring to those cells that produce a single type of daughter cell; e.g., a unipotent stem cell.

Characterized by a large appetite or a big stomach; being a glutton.

1. Developed in manhood; hence, able to beget; marriageable, considered fit for marriage.
2. Possessed of masculine strength or energy.

Willing and able.

Motto on the original State seal of Nevada, USA.

Viewed from the United States or Asia, Denmark is an environmental role model.

About one-fifth of the Denmark's electricity comes from wind, which wind experts say is the highest proportion of any country.

A closer look shows that Denmark is a far cry from a clean-energy paradise.

The building of wind turbines has virtually ground to a halt since subsidies were cut back.

Meanwhile, compared with others in the European Union, Danes remain above-average emitters of the greenhouse gas carbon dioxide.

For all of its wind turbines, a large proportion of the rest of Denmark's power is generated by plants that burn imported coal.

Danish experience shows how difficult it can be for countries grown rich on fossil fuels to switch to renewable energy sources like wind power.

Among the hurdles are fluctuating political priorities, the high cost of putting new turbines offshore, concern about public acceptance of large wind turbines, and the destructive volatility of the wind itself.

Some parts of western Denmark derive 100 percent of their peak needs from wind if the breeze is up.

Germany and Spain generate more power in absolute terms, but in those countries wind still accounts for a far smaller proportion of the electricity generated. The average for all 27 European Union countries is three percent.

The Germans and the Spanish are catching up as Denmark slows down.
