SC.912.N.1.1 ANALYZING DATA; EVALUATING SCIENTIFIC INVESTIGATIONS
An osmosis investigation was conducted using chicken eggs to represent cells with semipermeable membranes. The mass of each egg was measured to determine how much water diffused into or out of the eggs. The eggs were first soaked in vinegar to dissolve the shell. Each egg was then placed in one of three different solutions for 24 hours. The table below shows the results of the investigation.
Based on this experiment, which of the following should be inferred about cells with semipermeable membranes?
Water enters the cell when placed in environments of high water concentration.
Substances other than water may block pores in the cell membrane.
Water leaves the cell when placed in environments with a low concentration of solutes.
Substances other than water may also cross the cell membrane.

Atmospheric carbon dioxide levels have been rising at about the same rate for the past century.
Atmospheric carbon dioxide levels are responsible for global temperature change.

Cells form through spontaneous generation.
Cells are the basic structural and functional units of life.
The combined observations of Mattias Schleiden, Theodor Schwann and Rudolph Virchow resulted in the formation of the cell theory. Which of the following is not part of the cell theory?

Which of the following would most likely cause a mutation?
The insertion of a nucleotide into DNA.
The release of messenger RNA from DNA.
The placement of ribosomes on the endoplasmic reticulum.
The movement of transfer RNA out of the nucleus.
During transcription the DNA base sequence is transcribed into a complimentary mRNA sequence. A codon table like the one shown below lists the amino acids coded for by particular triads of mRNA bases. A segment of DNA has undergone a mutation in which one nucleotide has been changed. The original sequence was ACG and the new sequence is ACA. Use the codon table to determine whether or not this mutation will cause a change in the phenotype of the organism.
It is impossible to determine if a change in phenotype will occur using only the DNA sequence.
Yes, the phenotype of the organism would change because any change in the DNA sequence will cause a change in phenotype.
Yes, the phenotype of the organism would change because a new amino acid will be coded for.
Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.

SC.912.L.18.9 PHOTOSYNTHESIS-PRODUCTS; ROLE OF ATP
A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?
As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
The cells will never run out of oxygen if the weightlifter is breathing.
As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen.
How are cellular respiration and photosynthesis related, in terms of energy?
Energy is not involved in either photosynthesis or cellular respiration.
The energy captured in photosynthesis is used to power cellular respiration.
The energy transformed in cellular respiration is used to power photosynthesis.

This information shows which of the following
DDT and other pesticides cause glacier runoff during the summer.
It takes humans over 50 years to analyze a glacier.
The decision of one human generation may have an impact on future generations.
Precipitation helps to break down pesticides.
