Biology Benchmark 2 Practice #1

Where does photosynthesis take place in a cell?

• chloroplast

• mitochondrion

• nucleus

• ribosome

The model shows that proteins in two different organisms are made from the same amino acids but in a different order.

Why can different organisms have the same type of amino acids?

• The organisms have the same type of organs.

• The organisms have the same type of nucleotides.

• The organisms use the same type of enzymes.

• The organisms eat the same type of foods.

Which is the best example of a cell maintaining homeostasis through active transport?

• a cell releasing a molecule without energy

• a cell releasing carbon dioxide waste into the environment

• a cell engulfing a large molecule

• a cell exchanging equal amounts of water with the environment

The diagram shows the different phases of the cell cycle.

Which explains a similarity and difference between the G 1 and G 2 phases?

• During both phases, the cell experiences cell growth; however, the nucleus re-forms during

  G2 .

• During both phases, the cell experiences cell growth; however, a rapid increase in proteins for cell division occurs during G2 .

• During both phases, the cell repairs organelles; however, a slow decrease in the number of chromosomes occurs during G1 .

• During both phases, the cell repairs organelles; however, the cell membrane shrinks during

  G1 .

Which image shows a cell using active transport?

• 
• 
• 
• 

• Only the Y chromosome must have the allele for the trait to make a male hemophilic.

• Only one X chromosome must have the allele for the trait to make a female hemophilic.

• Both X chromosomes must have the allele for the trait to make a female hemophilic.

• Both the X and Y chromosomes must have the allele for the trait to make a male hemophilic.

A scientist uses mealworms to examine the effect of temperature on the rate of carbon dioxide production from cellular respiration. The scientist places the mealworms in three different glass containers under different temperature conditions. Each container has a carbon dioxide sensor and a stopper. The graph shows the changes in carbon dioxide concentration for 10 minutes.

How does temperature affect the rate of cellular respiration in mealworms?

• The rate of cellular respiration increases at a faster rate when the temperature is 39°C.

• The rate of cellular respiration decreases at the slowest rate when the temperature is 0°C.

• The rate of cellular respiration remains constant when the temperature is cooler than 39°C.

• The rate of cellular respiration remains constant when the temperature is warmer than 0°C.

Which combination of alleles will be present in normal daughter cells?

A student has carbohydrates in four different solutions with different pH values. The student adds an enzyme to each solution. After 10 minutes, the student tests the solutions for the presence of the enzyme and carbohydrate. The table shows the results.

Which is true about the enzyme?

• The enzyme is harmful in the body as it works best at a pH of 3.

• The enzyme has a specific pH range in which it can break down the carbohydrate.

• The time needed for the enzyme to break down the carbohydrate increases as pH increases.

• The presence of the enzyme after 10 minutes indicates that it is unable to interact with the carbohydrate.

What is the complementary DNA strand for the DNA strand CCAGGAGAG?

• GGTCCTCTC

• TTGAAGAGA

• TTGAAGAGA

• CCAGGAGAG
