POST UTME BABCOCK UNIVERSITY 2024 Biology | Objective
Practice these randomly selected questions to test your readiness.
Question 1
A patient is diagnosed with a genetic disorder that affects the production of a specific enzyme. The patient's doctor prescribes a medication that increases the production of the enzyme. What is the likely effect of the medication on the patient's symptoms?
Question 2
The type of tissue that is found in the walls of blood vessels and is responsible for the exchange of oxygen and carbon dioxide is called \n\( \text{\endothelium} \).
Question 3
A population of rabbits is growing exponentially, with a birth rate of 0.05 per rabbit per year and a death rate of 0.01 per rabbit per year. What is the carrying capacity of the population?
Question 4
In a population of E. coli, the frequency of a particular gene is 0.4. If 1000 bacteria are randomly selected, what is the expected number of bacteria that will be heterozygous for this gene?
Question 5
In a xylem vessel, water and minerals are transported from the roots to the leaves through a process called
Question 6
The process by which an organism becomes adapted to its environment over a long period of time is known as
Question 7
A 50-year-old woman has a history of hypertension and is taking a medication that blocks the action of angioten\sin II. What is the primary effect of this medication on the renin-angioten\sin-aldosterone system (RAAS)?
Question 8
In a photosynthetic reaction, what is the primary function of the light-dep\endent reactions?
Question 9
A diagram shows a simple food chain with a producer (plant), a primary consumer (insect), and a secondary consumer (bird). If the producer is removed, what will happen to the population of the secondary consumer?
Question 10
The genetic material that is responsible for the transmission of traits from one generation to the next is known as
Question 11
A solution contains 0.1 M NaCl and 0.2 M CaCl2. What is the concentration of Cl- ions in the solution?
Question 12
A population of rabbits is growing \logistically according to the equation dP/dt = rP\( 1 - P/K \). If the initial population is 100 rabbits and the carrying capacity is 1000 rabbits, what is the population size after 5 years?
Question 13
The process by which an organism maintains a stable internal environment despite changes in the external environment is known as
Question 14
The human body has a unique system for transporting oxygen and nutrients to cells and removing waste products. This system is called
Question 15
A 2.5 L sample of a solution containing 0.15 M NaCl is titrated with 0.25 M HCl. What is the pH of the solution after the addition of 25 mL of HCl?
