Ants. An estimated 20,000 species of ants exist in the world. All ants live in colonies and have a structured social system, with different castes-worker, soldier, queen and drone-all of which carry out specific tasks for the colony.Only the queen and the males she mates with on her maiden flight will reproduce.All the workers and soldiers are sterile females.ll ants live in colonies and have a structured social system, with different castes-worker, soldier, queen and drone-all of which carry out specific tasks for the colony.

Students receive a scaled score for each of the four multiple-choice test sections (English, Math, Reading, and Science). A studentâs composite ACT score is the average of the studentâs scaled scores for the four multiple-choice test sections. Example: If a student scored a 24 English, 28 Math, 26 Reading, and 23 Science, his composite ACT score would be (24 + 28 + 26 + 23)/4 = 25.25, which is rounded down to a 25.
The test is composed of four sections: two Math Sections, Critical Reading, and Writing Skills, and takes two hours and ten minutes to complete. Originally, each of the three sections was scored on a scale of 20 to 80 points, adding up to a maximum composite score of 240 points. This paralleled the SAT, which is graded on a scale of 200 to 800 for each section (the narrower range is to distinguish from which test a score comes and to denote less accuracy).
