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 25-year-old woman presents with symptoms of hyperthyroidism. Which of the following is a potential cause?
Question 3
Which of the following evolutionary theories proposes that species adapt to their environments through the process of natural selection?
Question 4
A 20-year-old woman is diagnosed with polycystic ovary syndrome (PCOS). Which of the following is a potential underlying cause?
Question 5
The process by which the nervous system transmits signals is known as
Question 6
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 7
The Δ033[1m033[4m033[32mNervous033[0m033[39m033[0m system is responsible for transmitting signals from sensory receptors to the central nervous system. Which of the following types of sensory receptors are responsible for detecting changes in temperature?
Question 8
The sense organ responsible for detecting changes in light intensity is the
Question 9
The process by which plants convert light energy into chemical energy is known as
Question 10
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 11
The diagram below shows a simple circuit.
Question 12
A diagram of a human brain is shown below. What is the function of the structure labeled 'Z'?
Question 13
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 14
In a population of 1000 individuals, 20% are heterozygous for the ABO blood group system. If 10% of the population is type A, 5% is type B, and 2% is type AB, what is the probability that a randomly selected individual is type O?
Question 15
Which of the following biomes is characterized by a high level of precipitation and a diverse array of plant and animal species?
