Problem: Predation:

Aposematism, where organisms are brightly colored as a warning to predators, is the antithesis of camouflage. Some organisms pose a threat to their predators—for example they may be poisonous, or able to harm them physically. Aposematic coloring involves bright, easily recognizable and unique colors and patterns. For example, bright coloration in Variable Checkerspot butterflies leads to decreased predation attempts by avian predators. Upon being harmed (e.g., stung) by their prey, the appearance in such an organism will be remembered as something to avoid. While that particular prey organism may be killed, the coloring benefits the prey species as a whole.

What scientific term is used to describe  organisms that are brightly colored as a warning to predators?

A: Aposematism


Problem: It is thought that annelids were originally animals with two separate sexes, which released ova and sperm into the water via their nephridia. The fertilized eggs develop into trochophore larvae, which live as plankton. Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium (head); a small area round the trochophore's anus becomes the pygidium (tail-piece); a narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium (the segment that contains the mouth).
What does the trochophore become when annelids die?

Gymnastics is a sport involving the performance of exercises requiring strength, flexibility, balance and control. Internationally, all events are governed by the Fédération Internationale de Gymnastique (FIG). Each country has its own national governing body (BIW) affiliated to FIG. Competitive artistic gymnastics is the best known of the gymnastic events. It typically involves the women's events of vault, uneven bars, balance beam, and floor exercise. Men's events are floor exercise, pommel horse, still rings, vault, parallel bars, and the high bar. Gymnastics evolved from exercises used by the ancient Greeks that included skills for mounting and dismounting a horse, and from circus performance skills.

Context and question: Like the Speaker of the House, the Minority Leaders are typically experienced lawmakers when they win election to this position. When Nancy Pelosi, D-CA, became Minority Leader in the 108th Congress, she had served in the House nearly 20 years and had served as minority whip in the 107th Congress. When her predecessor, Richard Gephardt, D-MO, became minority leader in the 104th House, he had been in the House for almost 20 years, had served as chairman of the Democratic Caucus for four years, had been a 1988 presidential candidate, and had been majority leader from June 1989 until Republicans captured control of the House in the November 1994 elections. Gephardt's predecessor in the minority leadership position was Robert Michel, R-IL, who became GOP Leader in 1981 after spending 24 years in the House. Michel's predecessor, Republican John Rhodes of Arizona, was elected Minority Leader in 1973 after 20 years of House service.
