Living systems are incredibly diverse in size, shape, environment, and behavior. It is
estimated that there are between 10 million and 100 million different species. Despite this
wide variety of organisms, it remains difficult to define what is means to say something is
alive. Which of the following can be described as the smallest living unit?
A) DNA
B) cell
C) organelle
D) protein - Correct Ans✓✓ B
Which statement is NOT true about the events/conclusions from studies during the mid-
1800's surrounding the discovery of cells?
A) cells came to be known as the smallest universal building block of living organisms.
B) scientist came to the conclusion that new cells can be form spontaneously from the
remnants of ruptured cells
C) light microscopy was essential in demonstrating the commonalities between plant and
animal tissues
D) new cells arise from the growth and division of previously existing cell - Correct Ans✓✓
B
Although there are many distinct prokaryotic species, most have a small range of shapes,
sizes, and growth rates. Which of the following characteristics are NOT observed in
prokaryotes?
A) a highly structured cytoplasm
B) endoplasmic reticulum
C) the ability to divide rapidly

,D) a cell wall - Correct Ans✓✓ B
Biologists cannot possibly study all living species. Instead, they try to understand cell
behavior by studying a select subset of them. Which of the following characteristic are useful
in a n organism chosen for use as a model in laboratory studies?
A) amenability to genetic manipulation
B) ability to grow under controlled conditions
C) rapid rate of reproduction
D) all of the above - Correct Ans✓✓ D
Which statement is NOT true about mutations?
A) a mutation is a change in the DNA that can generate offspring less fit for survival than
their parents
B) a mutation can be a result of imperfect DNA duplication
C) a mutation is a result of sexual reproduction
D) a mutation is a change in the DNA that can generate offspring that are as fit for survival as
their parents are - Correct Ans✓✓ C
The flow of genetic information is controlled by a series of biochemical reactions that result
in the production of proteins, each with its specific order of amino acids. Choose the correct
series of biochemical reactions from the options presented here.
A) replication, transcription, translation
B) replication, translation, transcription
C) translation, transcription, replication
D) translation, replication, transcription - Correct Ans✓✓ A

, Proteins are important architectural and catalytic components within the cell, helping to
determine its chemistry, its shape, and its ability to respond to changes in the environment.
Remarkably, all of the different proteins in a cell are made from the same 20 _______. By
linking them in different sequences the cell can make protein molecules with different
conformations and surface chemistries, and therefore different functions.
A) nucleotides
B) sugars
C) amino acids
D) fatty acids - Correct Ans✓✓ C
Changes in DNA sequence from one generation to the next may result in offspring that are
altered in fitness compared with their parents. This process of change and selection over the
course of many generations is the basis of ______.
A) mutation
B) evolution
C) heriditiy
D) reproduction - Correct Ans✓✓ evoltuion
Select the option that best finishes the following statement: "Evolution is a precess _______."
A) that can be understood based on the principles of mutation and selection
B) that results from repeated cycles of adaption over billions of years
C) by which all present-day cells arose from 4-5 different ancestral cells
D) that requires hundreds of thousands of years - Correct Ans✓✓ A
Select the option that correctly finishes the following statement: "A cell's genome _______."
A) is defined as all the genes being used to make a protein
