POST UTME IMS U 2025 Biology | Objective
Practice these randomly selected questions to test your readiness.
Question 1
A diagram of the human digestive system is shown below. Which part of the digestive system is responsible for absorbing nutrients from food?
Question 2
A study on the genetic variation of a population found that 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 3
A bio\logist is studying the structure of a plant cell. The bio\logist observes that the cell has a large central vacuole, a nucleus, and a cell wall. What is the primary function of the cell wall in a plant cell?
Question 4
A 1.5-L sample of a gas is collected over water at a temperature of 25°C and a pressure of 1 atm. If the vapor pressure of water at 25°C is 23.8 mmHg, what is the partial pressure of the gas?
Question 5
A diagram of the human eye is shown below. Which part of the eye is responsible for detecting light?
Question 6
A diagram of a human eye is shown below. What is the function of the structure labeled 'Y'?
Question 7
A population of bacteria is growing exponentially. If the initial population is 100 and the population doubles every 2 hours, what is the population after 6 hours?
Question 8
The process of mitosis is essential for the growth and development of multicellular organisms. Which of the following stages of mitosis is characterized by the condensation of chromatin into visible chromosomes?
Question 9
The nervous system is responsible for transmitting and proces\sing information. Which of the following types of neurons is responsible for transmitting signals from sensory receptors to the central nervous system?
Question 10
The process of evolution is responsible for the diversity of life on Earth. Which of the following is a mechanism of evolution that involves the movement of genes from one population to another?
Question 11
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 homozygous dominant genotype?
Question 12
The process of mitosis is essential for the growth and development of multicellular organisms. Which of the following stages of mitosis is characterized by the separation of chromosomes into two daughter cells?
Question 13
In a eukaryotic cell, the process of mitosis is initiated by the breakdown of the nuclear envelope, which is triggered by the activation of the Δπδαλλεργερ \( anaphase-promoting complex \). What is the primary function of the Δπδαλλεργερ in this context?
Question 14
A diagram of a human brain is shown below. What is the function of the structure labeled 'Z'?
