Title: Turtle Cells and Human Skin

New research has demonstrated that turtles and humans may have had a common
ancestor 310 million years ago. A recent study looked at the genes responsible for the skin
layers of turtle shells compared to the genes for human skin. The findings of the study
suggest that about 250 million years ago, when turtle evolution split from other reptiles, a
mutation in a specifi c group of genes occurred. The basic organization of this group of genes
is similar in turtles and humans, and they produce the important skin proteins that produce
shells in turtles and protect against infection in the skin of humans.

Which cell structure is mainly responsible for releasing energy from food molecules in some single-celled organisms?
Ribsome
Chloroplast
Cell membrane
Mitochondrion
The data table below shows the presence or absence of DNA in four different cell organelles.


Information in the table suggests that DNA functions:
within cytoplasm and outside the cell membrane
both inside and outside the nucleus
only within energy-releasing structures
within cell vacuoles
Which organism is considered an exception to the cell theory because it has a noncellular structure?
algae
virus
bacterium
moss
Which sequence represents structures organized from least complex to most complex?
nerve cell → nucleus → nervous system → brain
nucleus → nerve cell → brain → nervous system
brain → nervous system → nucleus → nerve cell
nervous system → brain → nerve cell → nucleus
The cells in the diagram below were present in the same individual.


These cells are most similar in the:
amount of energy they release
type of proteins they synthesize
rate of their metabolism
information stored in their DNA
The cell theory states that:
all cells have nuclei that contain genetic information
living organisms are composed of cells that arise from preexisting cells
all cells regenerate and contain the same basic structures
organisms that lack certain organelles reproduce by binary fission
Which letter in the diagram below indicates an organelle that functions primarily in the synthesis of long chains of amino acids?

A
B
C
D
Base your answers to question 8 on the diagram below and on your knowledge of biology.


ONLY an electron microscope can be used to view:
bacteria
mitochondria
animal cells
viruses
Sequence the structures listed below in order from least complex to most complex.
1= least complex, 5= most complex
organ
cell
tissue
organism
organelle
Single-celled organisms are able to maintain homeostasis, even though they lack higher levels of organization such as organs and organ systems, because:
single-celled organisms do not carry out the same life processes as multicellular organisms
multicellular organisms do not rely on tissues or organs to carry out life processes
cell structures work together to maintain homeostasis in single-celled organisms
single-celled organisms are able to coordinate organ functions to maintain homeostasis
A student viewed a slide of an onion root tip with a compound light microscope. The photograph below represents what he saw.


In order to observe whether or not this root tip was growing, the student should:
switch to a higher magnification and look for evidence of cell division
switch to a lower magnification and look for evidence of cell division
switch to a lower magnification and add a stain to the onion root tip cells
switch to a higher magnification and add salt solution to the onion root tip cells
Viruses are exceptions to the cell theory, but they have some characteristics of living things. What is one of these characteristics?
They are made up of many specialized cells.
They contain genetic material.
They reproduce by mitosis.
They contain chlorophyll.
What structures are found within plant cells that you won't find in an animal cell? (select all that apply)
Nucleus
Chloroplasts
Cell Wall
Mitochondria
Many biotic factors affect individuals in a population. An example of an organism being directly affected by a biotic factor is:
a squirrel cannot find a mate
a flood washes away a maple tree
a plant is in a dark room
a chipmunk finds a rock pile to use for a home
Bacteria and humans are similar in that they both:
contain genetic material
are single-celled
lack cell organelles
carry out autotrophic nutrition
After a lake dried up during a severe drought, a section of undisturbed rock layers was exposed. The layers are represented below.


This sequence of rock layers best illustrates the concept that:
the living and nonliving environment both change over time
it is important to preserve the diversity of species and habitats
new inheritable characteristics can result from the recombining of genes
living organisms have the capacity to produce populations of unlimited size
Base your answer to question 20 on the information to the left and on your knowledge of biology.
Question 20
20.

Identify the molecule that contains the hereditary material and the organelle in which it is found in turtle cells. (Example: molecule, organelle in turtle cells)
