2021 — Ss1 Second Term Biology Exam Questions

The removal of metabolic waste products from the body is called ______. A) Egestion B) Secretion C) Excretion D) Osmoregulation

The process by which a cell divides into two identical daughter cells is:A. MeiosisB. MitosisC. DiffusionD. Osmosis

: Types of skeletons (hydrostatic, exoskeleton, endoskeleton); the axial skeleton (skull, vertebral column) and appendicular skeleton (limbs, girdles); and types of joints (hinge, ball and socket). Plant Biology

Which of the following is a biotic component of an ecosystem?A. Soil pHB. HumidityC. DecomposersD. Sunlight ss1 second term biology exam questions

A. Species B. Order C. Kingdom D. Phylum

In mammals, the structure that prevents food from entering the trachea during swallowing is the ______. A) Pharynx B) Epiglottis C) Glottis D) Larynx

– Resources like minerals and fossil fuels cannot be replaced once exhausted. The removal of metabolic waste products from the

A. Cells are the structural and functional units of life. B. New cells come only from pre-existing cells. C. Cells contain genetic material (DNA). D. All cells have a cell wall.

Another significant characteristic is the integration of practical biological principles with theoretical knowledge. Nigerian biology exams often bridge the gap between the classroom and the laboratory. Questions frequently refer to common experiments. For example, a student might be asked to “Draw and label the experimental setup used to demonstrate that carbon dioxide is necessary for photosynthesis” or “Predict the result of the starch test on a leaf from a plant kept in a dark cupboard for 48 hours.” These questions assess a student’s observational skills and their ability to reason through empirical evidence. This reflects a curriculum that, at its best, aims to produce not just theorists but budding scientists who understand the scientific method.

a) Define Population Density .b) List four factors that can affect the growth of a population.c) Describe one method used to carry out population studies in a habitat. MitosisC

– This graph shows the population of each trophic level in a food chain.

In conclusion, the SS1 Second Term Biology exam questions are a sophisticated instrument of pedagogy. They meticulously assess the student's journey from rote memorization to analytical reasoning, from isolated facts to integrated systems. While they effectively target core topics like nutrition, transport, and respiration using a balanced taxonomy of questioning, there is always room for growth—specifically in making the content more locally relevant and in reducing the over-reliance on pure recall. For the diligent SS1 student, these questions are not a hurdle to be feared but a framework to be mastered. They are the stepping stones to the advanced sciences of SS2 and SS3, and ultimately, to a future career in medicine, agriculture, or biotechnology. In every carefully worded prompt lies an invitation to wonder about the intricate machinery of life itself.
