Practice these randomly selected questions to test your readiness.
Question 1
In a population of 1000 individuals, the frequency of the recessive allele 'a' is 0.2. If the population is in Hardy-Weinberg equilibrium, what is the frequency of the dominant allele 'A'?
Question 2
The nervous system is responsible for transmitting signals between different parts of the body. Which of the following is NOT a type of neuron?
Question 3
In the context of sexual reproduction, what is the term for the process by which two alleles of a gene are separated during meiosis?
Question 4
The process of natural selection is a key mechanism of evolution. Which of the following is a characteristic of a population that is undergoing natural selection?
Question 5
A 5-year-old child is diagnosed with a rare genetic disorder. The child's parents are both carriers of the recessive allele 'a'. What is the probability that the child will be affected by the disorder?
Question 6
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 frequency of the dominant allele 'A'?
Question 7
A diagram of a plant cell is shown below. What is the function of the part labeled 'B'?
Question 8
A plant with the genotype AaBbCcc is crossed with a plant with the genotype AabbCC. What is the probability that the offspring will have the genotype AaBbCc?
Question 9
A patient has a disease caused by a virus that replicates according to the equation \( \frac{dV}{dt} = rV left\( 1 - \frac{V}{K} \right \ \) ), where \( r = 0.1 \) and \( K = 100 \). If the initial viral load is 10, find the viral load after 10 time units.
Question 10
In a forest e\cosystem, a population of deer is limited by the availability of food. If the deer population grows \logistically according to the equation \( \frac{dP}{dt} = rP left\( 1 - \frac{P}{K} \right \ \) ), where \( r = 0.2 \) and \( K = 100 \), find the carrying capacity of the e\cosystem.
Question 11
In the context of classification of living things, which of the following kingdoms is characterized by the presence of true branching and vascular tissues?
Question 12
In the context of blood transport, which of the following is a characteristic of the erythrocyte?
Question 13
The nervous system of an organism is responsible for
Question 14
A population of 1000 individuals has a mean height of 170 cm and a s\tandard deviation of 10 cm. What is the probability that a randomly selected individual will have a height between 160 cm and 180 cm?
