Small-scale fishing performed with nets is one of the most common fishing methods used around the world. One of the unfortunate side effects of this method is that sea turtles, which are considered threatened, get caught in the nets along with the fish. Conservation biologists at the University of Exeter in England recently devised a way to prevent these sea turtle deaths, which they tested at a fishery in northern Peru. They found that attaching green LED lights to the nets warned the turtles away, possibly because the lights made the nets more visible. The number of sea turtle deaths was reduced, but the number of fish caught seemed to remain the same.

Biologists recognize five levels of cell organization. the lowest and simplest is the cellular level. organisms here are either unicellular organisms, like protozoa, or colonial organisms. colonial organisms are composed of single-celled individuals that stay together to sustain the life of the whole colony. next on the scale of complexity is the level occupied by tissue. a tissue is a group of similar cells which perform a similar activity. tissues that are organized around a common function together make up an organ, the third level of complexity. the fourth level of organization is the system, formed by a group of organs which together perform a specific bodily process. the fifth and highest level is the organism level, in which body systems work together in a structure capable of independent life. main idea:
