TEAS 7 Science spans human anatomy and physiology, biology, and chemistry the scientific foundation nursing programs assume you already have before your first anatomy course.
Glycerophospholipids are a class of chemicals known as "amphipathic" because they contain sections that are both hydrophilic and hydrophobic. Which portion of a glycerophospholipid accounts for its hydrophilic character?
Which of the following observations refutes the hypothesis that characteristics acquired during a parent's lifetime are inherited by its offspring (i.e., refutes Lamarckian inheritance of acquired traits)?
Once you're comfortable with science, try a full TEAS 7 practice test to see how it holds up under timed, mixed-section conditions, or head back to all TEAS 7 categories.
The following information must be communicated in a general newspaper article: "Most living animal species belong to the infrakingdom Bilateria, a highly proliferative clade whose members have a bilaterally symmetric body plan. The vast majority belong to two large superphyla: the protostomes, which include organisms such as the arthropods, mollusks, flatworms, annelids, and nematodes; and the deuterostomes, which include the echinoderms, hemichordates, and chordates, the latter of which contains the vertebrates." Which of the following types of graphs should the editor use to best present this information and show the hierarchical relationships and overlap between the different organism groups?
