Practice these randomly selected questions to test your readiness.
Question 1
What is the process by which plants convert light energy into chemical energy?
Question 2
The xylem is a type of vascular tissue found in plants that is responsible for transporting water and minerals from the roots to the leaves. Which of the following is a characteristic of xylem tissue?
Question 3
A 50-year-old man has a blood pressure of 180/100 mmHg. If he is prescribed a diuretic that reduces his blood pressure by 20%, what is his new blood pressure?
Question 4
A patient is diagnosed with a bacterial infection caused by Staphylococcus aureus. The patient is prescribed a course of antibiotics that is effective against the bacteria. However, the patient develops a resis\tance to the antibiotics after 5 days of treatment. What is the most likely reason for the development of resis\tance?
Question 5
In a population of Drosophila melanogaster, the frequency of the recessive allele 'a' is 0.2. If the population is in Hardy-Weinberg equilibrium, what is the expected frequency of the homozygous dominant genotype 'AA'?
Question 6
The genetic material that is passed from one generation to the next is called?
Question 7
A 50-g sample of a subs\tance is digested and the resulting CO2 is collected over water at 20°C and 1 atm. If the volume of CO2 collected is 2.5 L, what is the percentage of carbon in the original subs\tance?
Question 8
A study on the genetic variation of a population found that the frequency of the recessive allele is 0.2. If the population size is 1000, what is the expected number of homozygous recessive individuals?
Question 9
A researcher is studying the effect of pH on the growth of a microorganism. The researcher sets up an experiment with three different pH levels: 5, 7, and 9. The researcher measures the growth of the microorganism at each pH level and finds that the growth is highest at pH 7. What is the most likely reason for the optimal growth at pH 7?
Question 10
In a population of 1000 individuals, the frequency of the dominant allele for a particular trait is 0.6. If the population is in Hardy-Weinberg equilibrium, what is the frequency of the recessive allele?
Question 11
A cell has a membrane potential of -70 mV and a resting potential of -60 mV. If the cell is stimulated and the membrane potential changes to -50 mV, what is the percentage change in the membrane potential?
Question 12
In a photosynthetic pathway, which enzyme catalyzes the conversion of ribulose-1,5-bisphosphate to 3-phosphoglycerate?
Question 13
A 30-year-old woman has a body mass index (BMI) of 25. If she gains 10 kg, what is her new BMI?
Question 14
The human immune system is a complex network of cells, tissues, and organs that work together to def\end the body against pathogens. Which of the following is a type of white blood cell that plays a key role in the immune response?
Question 15
