POST UTME SKYLINE UNIVERSITY 2024 Biology | Objective
Practice these randomly selected questions to test your readiness.
Question 1
The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain cons\tant from generation to generation in the absence of other evolutionary influences. However, this principle assumes that the population is "panmictic", meaning that individuals mate randomly with respect to genotype. Which of the following is a consequence of this assumption?
Question 2
A diagram of a plant cell is shown below. What is the function of the structure labeled 'X'?
Question 3
A population of 1000 individuals is divided into 10 equal-sized groups. Each group is given a different diet, and the effect on the population's average height is measured. If the average height of the population increases by 2 cm after 10 years, what is the probability that the increase is due to the diet rather than other factors?
Question 4
The type of classification that groups living organisms based on their evolutionary relationships is known as
Question 5
In a eukaryotic cell, the process of cell division that results in the production of four daughter cells is known as
Question 6
A 20-year-old woman is diagnosed with polycystic ovary syndrome (PCOS). Which of the following is a potential underlying cause?
Question 7
A researcher is studying the effect of pH on the growth of E. coli. The researcher measures the growth of E. coli at different pH levels and plots the data on a graph. If the graph shows a sigmoidal curve with a Hill coefficient of 2, what is the type of enzyme that is most likely responsible for the observed growth?
Question 8
In the context of transport systems, what is the primary function of the xylem in plants?
Question 9
A diagram of a human brain is shown below. What is the function of the structure labeled 'Z'?
Question 10
The sense organ responsible for detecting changes in light intensity is the
Question 11
In the process of Δ033[1m033[4m033[32mRespiration033[0m033[39m033[0m, the breakdown of glu\cose to produce ATP occurs in the Δ033[1m033[4m033[32mMitochondria033[0m033[39m033[0m. Which of the following is the primary electron acceptor in the electron transport chain?
Question 12
The process by which plants convert light energy into chemical energy is known as
Question 13
The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain cons\tant from generation to generation in the absence of other evolutionary influences. However, this principle assumes that the population is "panmictic", meaning that individuals mate randomly with respect to genotype. Which of the following is a consequence of this assumption?
Question 14
A population of 1000 individuals is divided into 10 equal-sized groups. Each group is given a different exercise program, and the effect on the population's average strength is measured. If the average strength of the population increases by 5 kg after 10 years, what is the probability that the increase is due to the exercise program rather than other factors?
Question 15
The Δ033[1m033[4m033[32mHormonal033[0m033[39m033[0m system in animals is responsible for regulating various physio\logical processes. Which of the following hormones is responsible for stimulating the growth and development of the reproductive system?
