A peripheral smear with increased polychromasia, schistocytes and spherocytes is indicative of which condition? A. Aplastic anemia B. Iron deficiency anemia C. Hemolytic anemia D. Megaloblastic anemia - correct answer C. Hemolytic anemia Megaloblastic anemia would show larger, less mature RBCs on the smear. Iron deficiency anemia would show hypochromasia, and a lower RBC count. Aplastic anemia would show very little amounts of mature RBCs on the smear Hemolytic anemia results in miss...

CHEM120 Week 4 Concepts: The Ideal Gas Laws and Acid/Base Reactions- Download To Score An A+ PHYSICAL STATES OF MATTER In this section, we will discuss the Ideal Gas Laws. First, we will review the properties of solids, liquids, and gases. Second, we will discuss the kinetic-molecular theory of gases, which explains why they are so unique compared to other states of matter. Finally, we will discuss gas law equations, and practice using them to solve for different parameters. This unit has many s...
