Biology EOC Exam Questions and Answers Latest Update 2025 Graded A+
During asexual reproduction in a yeast cell, two daughter buds are formed. What is true about the
daughter buds formed in the process? - Answers Both daughters will have the same genetic information
as the parent cell.
An apartment being treated for roaches was sprayed with a pesticide. In the graph, the number of
roaches seen each day was plotted each day after the treatment. Day 0 represents the day before the
apartment was treated. What can you conclude from the graph? - Answers The treatment was only
effective as a short-term solution.
Can cell phone use lead to brain cancer?
Which technique would represent the MOST cost effective approach to conduct an investigation of this
research question? - Answers Do a literature review on previous studies done on this topic.
Biochemical analysis uses similarities in __________ as evidence for evolutionary relationships. -
Answers DNA sequences
The purpose of photosynthesis is to produce usable chemical energy or glucose from solar energy. If the
formula for glucose is C6H12O6, how many atoms of carbon are used to produce the glucose? - Answers
6
To test acidity levels of water, scientists test the pH. As acid rain falls, the pH levels in lakes and streams
decrease. While certain animals can tolerate low pH levels, others are extremely sensitive to the effects
of acid rain and cannot live under the conditions. Students in Maria's class know, based on the chart, the
pH range tolerated by specific organisms living in the ponds surrounding their school. Maria and several
other students are anxious to design an experiment to investigate this topic.
What would be an appropriate research question to guide their investigation? - Answers Is acid rain
decreasing the amount of bass and mayflies in local ponds?
According to the graph, when does the bacteria population reach its peak? - Answers Setember
What process IMMEDIATELY preceeded protein synthesis at the ribosome? - Answers Transcription
The diagram displays the copying of a DNA sequence from a gene before and after the copy is made. The
* represents an error that was made. Identify what this error is called. - Answers point mutation
You are trying to identify this nucleic acid. All BUT one observation is an important clue to the nucleic
acid's identity. That is it - Answers contains phosphate.
, A student conducts a science fair project to determine whether or not eating peanut butter increases
short-term memory.
What would probably NOT be a major concern for the student doing a science fair project? - Answers
make certain that none of her test subjects gets the same memory test.
During photosynthesis, hydrogen ions are most directly used to _____________ in the chloroplast
pictured above. - Answers drive the production of ATP
Which topic could be investigated using the scientific method, with the investigation organized around a
appropriate research question? - Answers the natural world
ATP is considered to be an energy carrier molecule. Where is the energy actually located in this
molecule? - Answers in the bonds between phosphate groups
Ms. Mayo challenged her students to build a pendulum that would hit a block of wood and make it
travel the farthest distance. The group that moved the block of wood the most would win a prize. One
group's experimental data is shown above.
What is this group's independent variable? - Answers mass of pendulum bob
Most of the ATP made during cellular respiration is produced in which organelle? - Answers
mitochondria
Tiny plastic pellets, like the pellets in the image, enter marine ecosystems through accidental spillage or
by the decomposition of plastic wastes.
How do these pellets affect marine ecosystems? - Answers They are consumed by fish and marine
mammals and block the digestive systems of these organisms.
Which question can be used to form a hypothesis? - Answers what affects the growth of corn?
In the food web the amount of matter - Answers remains constant
Scientists use DNA sequencing to understand relationships among life on Earth. The chart illustrates
differences between five species and humans. Although the DNA sequence of each may vary, all BUT
ONE statement concerning the organisms is true. - Answers The DNA sequences may vary but the amino
acid sequences are identical.
Carol and her lab partner were trying to estimate the number of Volvox colonies in a 10 milliliter sample
of pond water. The colonies were too small to count with a hand lens. Carol suggested putting a sample
