HESI A2 BIOLOGY SECTION EXAM 2025
QUESTIONS AND ANSWERS
Nurses need to know biology at what level and why - ANS Basic biology and a cellular level to
regonise a change of problem and then implement a strategy to fix it.
Biology is - ANS The study of life and all living things (organisms)
single celled organisms - ANS prokaryotes (bacteria)
Multicellular organisms - ANS Organisms composed of many cells (Ex. tissue, humans, etc.)
All living things are made of - ANS cells originated from a pre existing cell. Smallest unit of
living things . Needed for survival
cell theory - ANS idea that all living things are composed of cells, cells are the basic units of
structure and function in living things, and new cells are produced from existing cells
Living things are organized into groups of - ANS Species
Species are - ANS groups of organisms that can potentially interbreed to produce fertile
offspring. Then those closely related organism are grouped into broader tacón tier called genus
Ascending organization (stupid grandma ****ing on children pushing kitties down ) -

(tests out an event or phenomenon)
Scientific Method uses what steps - ANS Observing , developing questions , researching what
other scientists have already done , creating a hypothesis that will predict the outcome of the
questions designed to test the hypothesis
Hypothesis - ANS An educated guess
compound microscope - ANS A light microscope that has more than one lens

certain properties of ___&_____ - ANS Matter and energy
Matter - ANS Anything that has mass and takes up space ( weights something's ) can be
liquid, solid or a gas
The building blocks of matter are ___ - ANS elements (helium , oxygen , chlorine , nitrogen,
potassium and radium )
The periodic table known as - ANS Chart of all known elements
Energy is - ANS the ability to do work, bring change or make things happen . Energy can be
shifted , converted and changed but cannot he created or destroyed .
