Hesi A2 2025 biology section Containing Exam Questions And
Correct Solutions.
Nurses need to know biology at what level and why - Basic biology and a cellular level to
regonise a change of problem and then implement a strategy to fix it.
Biology is - The study of life and all living things (organisms)
single celled organisms - prokaryotes (bacteria)
Multicellular organisms - Organisms composed of many cells (Ex. tissue, humans, etc.)
All living things are made of - cells originated from a pre existing cell. Smallest unit of living
things . Needed for survival
cell theory - 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 - Species
Species are - 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 ) - Species,
genus , family , order , class , phylum , kingdom , domain
Scientific Method - A logical, systematic approach to the solution of a scientific problem
(tests out an event or phenomenon)
, Scientific Method uses what steps - 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 - An educated guess
compound microscope - A light microscope that has more than one lens
The structure and organization of both living things and non living things are derived from
certain properties of ___&_____ - Matter and energy
Matter - Anything that has mass and takes up space ( weights something's ) can be liquid,
solid or a gas
The building blocks of matter are ___ - elements (helium , oxygen , chlorine , nitrogen,
potassium and radium )
The periodic table known as - Chart of all known elements
Energy is - the ability to do work, bring change or make things happen . Energy can be
shifted , converted and changed but cannot he created or destroyed .
Law of Conservation of Energy - Energy cannot be created or destroyed
Energy exists in many forms like - Light , heat , chemical , electrical. Energy or conversion of
energy is needed for cell life maintenance
Homeostasis - A tendency to maintain a balanced or constant internal state; the regulation of
any changes or disruptions
Organism - Living things that can sense and react to stimuli ( change, stress, or disruption)
reproduction (duplicate) , grow and develop , essentially evolve, transform (utilize and
convert ) energy and maintain internal balance (homeostasis)
