WKHS BIOLOGY EOC REVIEW - PART 1 - FALL 2019

Which statement can best be concluded from these data?

• The respiration rate in both species is independent of both temperature and oxygen consumption.

• The respiration rate of midge larvae increases more rapidly than the rate for seabird ticks at all temperatures.

• As the temperature increases, there is an inverse relationship between oxygen consumption and the respiration rate in both species.

• As the temperature increases, the respiration rate in both species increases, with the rate for midge larvae being higher than that for seabird ticks at all temperatures.

Marine scientists monitor atmospheric levels of carbon dioxide. As atmospheric levels rise, more of the gas dissolves in the oceans. Calcium carbonate (CaCO3) dissolves as more carbon dioxide enters the oceans. Marine organisms such as clams need CaCO3 to build their exoskeletons. Based on this information, which change is most likely to be a direct result of these increasing levels of oceanic carbon dioxide?

• Frequent rainfall will dilute the effect of the carbon dioxide in the water.

• There will be an overpopulation of oysters and other shelled marine species.

• The water level will rise and cause floods, damaging coastal ecosystems with contaminated water.

• Many species of marine organisms will be weakened, making them unable to produce and maintain their shells.

A landscaper researched five grass types recommended for use in South Carolina lawns. The landscaper decides to select a grass type that does not require much fertilizer, does not need constant watering, and grows best in direct sunlight. Which grass type best fits the criteria?

• perennial ryegrass

• Bermuda grass

• buffalo grass

• zoysia grass

A student constructed a model to illustrate some of the processes involved in the production of proteins in a eukaryotic cell.

Which statement correctly describes the structure and activity identified by the letter X?

• A tRNA molecule reacts with an amino acid to produce ribosomal RNA.

• A tRNA molecule transports an amino acid for incorporation into a polypeptide.

• An rRNA molecule carries an amino acid away from the site of protein synthesis.

• An mRNA molecule transports a single amino acid to the site of protein synthesis.

Examine the data table.

Select two statements that support the data and explain the movement of molecules across the cell membranes.

• As the NaCl moved into the potato cells, the potato increased in mass.

• The potatoes in the 0.00 g/mL solution increased in mass as water molecules moved into the potato cells.

• As the NaCl concentration decreased, the mass of the potato increased as water molecules moved out of the potato cells.

• The potatoes in the 0.050 g/mL solution lost the greatest amount of mass as water molecules moved out of the potato cells.

• As the NaCl concentration increased, the mass of the potato increased as more NaCl moved into the potato cells.

Scientists can measure the DNA content of cells by using a dye that binds to DNA. After treating a sample of cells with the dye, the dye will appear more intense in cells where the quantity of DNA is higher

During which stage or stages of the cell cycle would scientists observe the highest measurements of dye intensity?

• only during G1

• only during mitosis and cytokinesis

• the entire time that the cell is in interphase

• from late S through G2 and mitosis

The yew tree is a rare and slow-growing tree. Paclitaxel is an anticancer compound obtained from the bark of the yew tree. The extraction of the compound is expensive and damages the yew tree. Scientists have isolated and grown stem cells from a yew tree that could be used to produce paclitaxel.

Which statement describes an advantage of using stem cells from a yew tree to produce paclitaxel?

• Stem cells can be grown and reproduced in a laboratory

• Stem cells can differentiate into cells of a different species.

• Stem cells from plants are more useful in producing animal protein.

• Stem cells from plants are less likely to cause unfavorable mutations than stem cells from animals.

In a controlled experiment, a limited quantity of glucose was provided for cellular respiration. Researchers measured the quantity of reactants and products at the beginning of the experiment and again after 10 minutes.

How will the quantities of glucose, oxygen, and carbon dioxide most likely change after 10 minutes have passed?

• glucose will increase

  oxygen will increase

  carbon dioxide will decrease

• glucose will decrease

  oxygen will decrease

  carbon dioxide will increase

• glucose will decrease

  oxygen will increase

  carbon dioxide will increase

• glucose will increase

  oxygen will decrease

  carbon dioxide will decrease

This diagram represents part of the process of translation. One tRNA molecule has transported the amino acid methionine (met) to the mRNA. Another tRNA molecule has transported the amino acid tryptophan (trp) to the mRNA.

Which step is next during translation?

• The tRNA will attach to nucleotides in the cytoplasm.

• A peptide bond will form between the two amino acids.

• The mRNA carrying the amino acids will drop off the ribosome.

• The amino acids will be carried to the Golgi apparatus for packaging.
