Biology Second Semester Final Exam Review
Identify the letter of the choice that best completes the statement or answers the question.
Topics include: Cell Division; DNA replication and Protein Synthesis; Genetics; Evolution and Ecology
I. Permeability of a cell membrane:
The purpose of this lab is to see what can be let in or out of a membrane through diffusion. My
hypothesis was that the glucose will move from the beaker into the iodine bag because it is a
I. Enzyme Lab 1
The purpose of this lab is to explore how enzymes break down chemical bonds. The
enzyme matches the shape of the molecule and it latches onto it. Then a twitch happens and the
molecule is broken down. Specifically in this lab
I. Drugs and Daphnia- The Effect of Various Compounds on the Heart Rate of Daphnia
In this lab we studied the effects that certain compounds had on the Heart Rate of
Daphnia, "Water Fleas" (similar to crustaceans). We used Daphnia because the
Factors Affecting The Shape of The Active Site
I think that the heat will break the bonds between the R groups of the Enzyme because then the
molecular motion is way to fast and the shaking will break the bonds. The acids and bases will
Euglena Lab Part 1:
Many things went wrong with the first lab with Euglena so this time we decided as a
class to set up the experiment differently.
What's Right and What's Wrong?
In the first lab we had several troubles with receiving correct d
I. Osmosis Lab: Potatoes and Elodea
In this lab we interpreted results of how the potato cells reacted to different salt
environments (hypertonic, hypotonic, and isotonic). In the Plasmolysis part of the lab we looked at the
I. Why Are Cells So Small?
The purpose of this lab is to figure out why cells are so small. Why are human beings made of
trillions of cells instead of just a handful of organs and tissues. This is found out by studying di
I. Separation of Plant Pigments using Chromatograms
In this lab we separated mixtures into their component parts. We separated spinach
pigments using chromatography paper that is quick and efficient. Our solute was three
layers of mashed s
I. Lab: Energy Stored In Food
The purpose or reason why we did this lab is to find the heat energy from burning the
food. Different foods give off different amounts of heat energy. This lab is to help us
understand what types of food give off
How Are Blood Vessels Structured?
I could tell when systole was occurring and when diastole was occurring for several
reasons in the fishes tail. First, systole was occurring when the blood surged through the arteries and
moved forward. The di
