Sample Questions and Model Answers on Cell Biology and Genetics

As a Biology teacher, helping students prepare for important exams like JAMB is crucial. In this section, I will provide sample questions and model answers focused on the topics of Cell Biology and Genetics to help build familiarity with the format and content of questions in these areas.

What is the basic structural and functional unit of life?

The cell is the basic structural and functional unit of life. Cells are the smallest units that can carry out all the necessary functions of life.

What are the two main categories of cells?

The two main categories of cells are:

  1. Prokaryotic cells: These cells lack a defined nucleus and membrane-bound organelles. Bacteria are examples of prokaryotic cells.
  2. Eukaryotic cells: These cells have a defined nucleus and membrane-bound organelles. Plants, animals, fungi, and protists have eukaryotic cells.

What are the three parts of a nucleotide?

The three parts of a nucleotide are:

  1. Nitrogenous base: Adenine, Guanine, Cytosine, Thymine (DNA), Uracil (RNA)
  2. Pentose sugar: Deoxyribose (DNA), Ribose (RNA)
  3. Phosphate group

Nucleotides are the basic structural units of nucleic acids like DNA and RNA which store and transmit genetic information in living organisms.

In summary, familiarity with the structure of cells, the types of cells, the parts of a nucleotide, and the role of nucleotides will help in answering related questions on the JAMB Biology exam. With practice, these foundational concepts will become second nature.

Sample Questions and Model Answers on Ecology

As an aspiring Jamb candidate, preparing for the Biology section of the exam is crucial. To give you an idea of what to expect, I have provided some sample questions and model answers on the topic of Ecology:

Sample Question 1: Explain the meaning of ecological niche.

The ecological niche refers to the role or position of an organism within an ecosystem. It encompasses the organism’s habitat, how it interacts with other species, and its functional role within the community. The niche includes factors such as the food an organism eats, how and where it reproduces, shelter, temperature, and availability of resources. No two species can occupy the exact same ecological niche in a habitat.

Sample Question 2: Describe three types of ecological pyramids.

There are three main types of ecological pyramids:

  1. Pyramid of numbers: Represents the number of organisms at each trophic level in a food chain. The base is the largest, with decreasing numbers at higher levels.
  2. Pyramid of biomass: Depicts the total biomass (weight) of organisms at each trophic level. The base is the largest, with decreasing biomass at higher levels due to energy loss.
  3. Pyramid of energy: Shows the amount of energy available at each trophic level. The base has the maximum energy, with decreasing amounts at higher levels due to energy loss during transfer between levels.

Sample Question 3: Explain the factors that affect population growth.

Several factors influence the growth of a population:

  • Birth rate: The number of births per population size over a given period of time. A higher birth rate leads to faster population growth.
  • Death rate: The number of deaths per population size over a given period of time. A lower death rate results in faster population growth.
  • Immigration: The number of individuals moving into a population from other areas. This adds to the population size and increases growth.
  • Emigration: The number of individuals moving out of a population to other areas. This reduces the population size and slows down growth.
  • Carrying capacity: The maximum population size that can be sustained in a habitat based on the availability of resources and space. Population growth levels off as it approaches the carrying capacity.
  • Resource availability: The amount of resources such as food, water, and shelter that can support a population. More available resources enable faster population growth.

Sample Questions and Model Answers on Evolution, Classification and Diversity

As a JAMB candidate, you need to prepare adequately for questions on Evolution, Classification and Diversity. Here are some sample questions and model answers to help you in your preparation:

What is evolution?

Evolution is the gradual development of new species from pre-existing species over long periods of time through natural selection acting on random mutations and variations. Natural selection is the mechanism by which organisms with traits well-suited to their environment tend to survive and reproduce more than those less suited. Over many generations, natural selection can result in adaptations that make organisms better suited to their environments.

Explain the theories of evolution proposed by Lamarck and Darwin.

Lamarck proposed the theory of inheritance of acquired characteristics, stating that organisms can pass on traits they acquire during their lifetime to their offspring. For example, he believed that giraffes evolved long necks through generations of stretching to reach leaves high up in trees. This theory has been disproven.

Darwin proposed the theory of natural selection. He observed that organisms produce more offspring than can survive and reproduce given the constraints of food, space, and other resources in the environment. He proposed that organisms with traits that help them better adapt to their environment will survive and reproduce at a higher rate. Over generations, natural selection results in changes in the inherited characteristics of a population, allowing species to adapt to their environment. Darwin’s theory of natural selection is the foundation of modern evolutionary theory.

What is biodiversity?

Biodiversity refers to the variety of living species on Earth, including plants, animals, fungi, protists, bacteria, and all other living things. It encompasses diversity within and between species and ecosystems. Biodiversity is vital for supporting life on Earth, as each species plays an important role within ecosystems. The loss of biodiversity through human activity is an ongoing concern and threatens the health of our planet.

In summary, studying evolution, classification and diversity will equip you with foundational knowledge for Biology. I hope these sample questions and model answers provide guidance in your preparation for JAMB. Best of luck!
