ISTEP+: Biology I
End-of-Course Assessment
Released Items and Scoring Notes

Introduction
Indiana students enrolled in Biology I participated in the ISTEP+: Biology I Graduation
Examination End-of-Course Assessment (ECA) during the 2010-2011 test administration
windows
...
It is important to keep in mind that a
significant portion of a student’s score is calculated from the multiple-choice items on the
assessment, which are not addressed within this document

Question 1, Sample A – 3 points
Nucleus, mitochondria, and ribosomes
...
The mitochondria
is the powerhouse of the cell; its used for making energy for the cell
...

Notes: The student lists three structures and describes the function of each of the three (six key
elements)
...


Question 1, Sample B – 2 points
nucleus, cell membrane, ribosome
The nucleus of a cell is equivilent to a controll center, it controls everything that happens in a
cell
...
A
ribosome is used to create proteins
...

Please note that student responses are scored for science content only, not for accurate spelling,
grammar, or punctuation
...


The golgi aparatus filters the cell, the nucleus is like to power house, and the nuclear evelope
regulates what enters and leaves the nucleus
...

Please note that student responses are scored for science content only, not for accurate spelling,
grammar, or punctuation
...

The nucleus holds the all of the genetic information that the cell needs, the mitochondrion aids in
makin protiens, and the cell wall is what helps protect the cell and hold it together
...
The student correctly describes the function of the nucleus (three key
elements)
...

Question 2

Question 2
Key Elements
Homeostasis is the maintenance of a body’s internal environment
...

The body responds by not sweating, blood vessels constricting
...

Glucose level drops below a set point, pancreas secretes glucagon, glucose level rise
...

the maintaining of a constant internal environment
Describe a change inside or outside the human body that could affect homeostasis
of the human body and describe how the body might respond involuntarily to
that change
...

Please note that student responses are scored for science content only, not for accurate spelling,
grammar, or punctuation
...

Homeostasis is the process of regulating the body's functions
...

If it is very cold outside, the body may shiver
...
This is also an act
of homeostasis
...

Please note that student responses are scored for science content only, not for accurate spelling,
grammar, or punctuation
...

homeostasis is the equal balance of living
...

Describe a change inside or outside the human body that could affect homeostasis
of the human body and describe how the body might respond involuntarily to
that change
...

Notes: The student provides an incorrect definition of homeostasis, but correctly describes a
change that could affect homeostasis; the description of how the body might respond to that
change is incomplete (one key element)
...

Question 2, Sample D – 0 points
Define the term homeostasis
...

Describe a change inside or outside the human body that could affect homeostasis
of the human body and describe how the body might respond involuntarily to
that change
...

...

AND
Mutation is not occurring in its gametes
...

The trait will not be inherited because the growth prevents them from reproducing
...

The potential cause of these growths is that the industrial park polluted the water that the fish
lives in, so the cells didn't get the message of what they were supposed to make so they started
dividing more rapidly
...

It is not likely that this trait will be inherited by the next generation, because it is not a inheritable
trait
...

Please note that student responses are scored for science content only, not for accurate spelling,

...

some kind of radioactive substance must have been put in the pond causing the cell to form
mutations

Is it likely that this trait will be inherited by the next generation? Explain why or why not
...

defect in their traits passed on by their parents
Is is likely that this trait will be inherited by the next generation? Explain why or why not
...

Please note that student responses are scored for science content only, not for accurate spelling,
grammar, or punctuation
...

Alleles are independently assorted during reproduction
...

Alleles are passed on to offspring
...

Alleles determine individual’s genotype and phenotype
...

AND
Assortment of and changes in alleles can lead to variation within a species, which may lead
to better survival and reproduction (evolution)
...

OR
Other plausible description of the connection between alleles and evolution

Question 4, Sample A – 3 points
Alleles are either dominant or recessive, usually the dominant trait is shown
...
The necessary traits are passed on and the organisms without the necessary traits
die
...
”
Please note that student responses are scored for science content only, not for accurate spelling,

...
They determine what the offspring will look like
...
Different variation in alleles vary and change
...
” However, the student provides no explanation of how natural
selection is affected
...


Question 4, Sample C – 1 point
Alleles are inherited independently
...
The variation
provides the species new gene or characteristic
...
” However,
the student provides two incorrect responses: “alleles are not forced to be inherited” and
“variation provides the species new gene or characteristic
...

Question 4, Sample D – 0 points
Both parents contribute DNA to their offspring
...
When natural selction has occured you can often predict what the offspring may look like
