HESI A2 BIOLOGY STUDY GUIDE
In the hierarchic system of classification which is the least inclusive? - Species
After observing an event, you develop an explanation this is: - Hypothesis
A molecule of water is bonded with another molecule of water by what type of bond? -
Hydrogen
Which is a benefit of the intermolecular hydrogen bonding of water: - 1- Water has a
relatively high specific heat value.
2- Water has strong cohesive and adhesive properties.
3- Polarity of water allows it to act as a versatile solvent.
Of all molecules that are significant to biology which are considered important: - nucleic
acids
Lipids are better known as fats but what are they specifically? - Fatty acids,
phospholipids, steroids
What are the 2 categories of fatty acids? - saturated fats and unsaturated fats
How do phospholipids function in cells? - They are integral components of plasma
membrane
Which of the biologic molecules are considered the most significant contributor to
cellular function? - Proteins
Proteins are polymers of which? - Amino Acids
Which of the following proteins catalyze different reactions or processes? - Enzyme
Which of the biologic molecules are components of the molecules of inheritance? -
Nucleic Acids
What is the sum of all chemical reactions that occur in an organism? - Metabolism
In a cell, reactions take place in a series of steps called: - Metabolic pathways
What is the fundamental unit of biology? - Cell
Which type of cell contains no defined nucleus? - Prokaryotic cell
