POST UTME MOUNTAIN TOP UNIVERSITY 2024 Biology | Objective
Practice these randomly selected questions to test your readiness.
Question 1
A population of 1000 individuals has a mean height of 170 cm. If a sample of 50 individuals is randomly selected from the population, what is the s\tandard deviation of the sample mean?
Question 2
The diagram below shows the structure of a plant cell. Which of the following organelles is responsible for the synthesis of proteins?
Question 3
In a eukaryotic cell, the process of mitosis is initiated by the breakdown of the nuclear envelope, which is mediated by the action of which of the following proteins?
Question 4
A diagram of a plant cell is shown below. Identify the part labeled A.
Question 5
A diagram of a plant cell is shown below. Identify the part labeled A.
Question 6
The process of cellular respiration in cells involves the breakdown of glu\cose to produce energy, which is stored in the form of which of the following molecules?
Question 7
In a typical mammalian kidney, which of the following structures is primarily responsible for the reabsorption of glu\cose from the filtrate?
Question 8
The type of connective tissue that provides support and structure to the body is?
Question 9
In a population of Drosophila melanogaster, the frequency of the recessive allele 'a' is 0.2. If the population size is 1000, what is the expected number of homozygous recessive individuals?
Question 10
A diagram of a human respiratory system is shown below. Identify the part labeled B.
Question 11
In a population of 1000 individuals, 20% are homozygous dominant (BB), 40% are heterozygous (Bb), and 40% are homozygous recessive (bb). What is the probability that two individuals chosen at random will have offspring with the BB genotype?
Question 12
In the xylem transport system, what is the primary function of the tracheids?
Question 13
The process of photosynthesis in plants involves the conversion of light energy into chemical energy, which is stored in the form of which of the following molecules?
Question 14
A researcher is studying the population dynamics of a species of rabbit. The population growth rate is modeled by the \logistic equation dP/dt = rP\( 1 - P/K \), where P is the population size, r is the intrinsic growth rate, and K is the carrying capacity. If the intrinsic growth rate is 0.5 and the carrying capacity is 1000, what is the population size at equilibrium?
Question 15
A 5.0-mL sample of a solution containing 0.2 M glu\cose is added to a 15.0-mL sample of a solution containing 0.1 M glu\cose. What is the resulting concentration of glu\cose in the mixture?
