About This Quiz

Below is a general science practice test! Regularly testing yourself on things you have learnt gives you an idea of how much information you have retained. One of the things we learn in science are different elements and the types of reactions that occur when some of them come together. Do take up the quiz and not only refresh your memory on reactions, different elements but the human body as well.

    Which one of these planets is the biggest in our solar system?

    • Earth

    • Saturn

    • Jupiter

    • Neptune

    Correct Answer
    A. Jupiter
    Explanation
    Jupiter is the correct answer because it is the largest planet in our solar system. It has a diameter of about 86,881 miles, which is more than 11 times the diameter of Earth. Jupiter's massive size is due to its composition, primarily consisting of hydrogen and helium gases. Its enormous size and strong gravitational pull have also allowed it to accumulate a large number of moons, with the current count being 79 confirmed moons.

    Which of these planets is not one of the inner planets of our solar system?

    • Mars

    • Earth

    • Saturn

    • Mercury

    Correct Answer
    A. Saturn
    Explanation
    Saturn is not one of the inner planets of our solar system. The inner planets, also known as terrestrial planets, are Mercury, Venus, Earth, and Mars. Saturn is a gas giant and is located beyond the asteroid belt, making it one of the outer planets.

    Which one of these living things is a decomposer?

    • Beetle

    • Shelf Fungus

    • Fern

    • Grasshopper

    Correct Answer
    A. Shelf Fungus
    Explanation
    Shelf fungus is a decomposer because it obtains nutrients by breaking down dead organic matter, such as fallen trees or decaying plant material. Decomposers play a crucial role in the ecosystem by recycling nutrients and returning them to the soil, allowing other organisms to utilize them. Beetles, ferns, and grasshoppers are not decomposers; they are either consumers or producers in the food chain.

    Alexander Fleming won the Nobel Prize for the discovery of what?

    • Stethoscope

    • Penicillin

    • South America

    • X Rays

    Correct Answer
    A. Penicillin
    Explanation
    Alexander Fleming won the Nobel Prize for the discovery of penicillin. Penicillin is a type of antibiotic that revolutionized the field of medicine by effectively treating bacterial infections. Fleming discovered penicillin in 1928 when he noticed that a mold called Penicillium notatum inhibited the growth of bacteria. This discovery led to the development and mass production of penicillin, which has saved countless lives and is still widely used today.

    Which of these animals is an herbivore?

    • Black Bear

    • Cottontail Rabbit

    • Cheetah

    • Red-Tailed Hawk

    Correct Answer
    A. Cottontail Rabbit
    Explanation
    The correct answer is Cottontail Rabbit. Cottontail rabbits are known to be herbivores, meaning they primarily eat plants and vegetation. This is in contrast to the other animals listed. Black bears are omnivores, meaning they eat both plants and animals. Cheetahs are carnivores, as they primarily eat meat. Red-tailed hawks are also carnivores, as their diet consists mainly of small mammals and birds.

  • 7. 

    Which of these is an example of a producer in a food chain?

    • Mushroom

    • Grass

    • Great Blue Heron

    • Rabbit

    Correct Answer
    A. Grass
    Explanation
    Grass is an example of a producer in a food chain because it is able to produce its own food through photosynthesis. Producers are organisms that convert sunlight energy into chemical energy, which is then consumed by other organisms in the food chain. Grass serves as a primary source of food for herbivores like rabbits, which are then consumed by predators. Therefore, grass plays a crucial role in the transfer of energy and nutrients within the food chain.

    Which of these is an example of an extinct animal?

    • Monitor Lizard

    • Saber-Tooth Cat

    • Rhinoceros

    • Bald Eagle

    Correct Answer
    A. Saber-Tooth Cat
    Explanation
    The Saber-Tooth Cat is an example of an extinct animal. It existed during the Pleistocene era and is known for its long, saber-like canine teeth. The species became extinct around 10,000 years ago, likely due to a combination of climate change and competition for resources. Fossil evidence and scientific research have provided insights into the behavior and physical characteristics of this ancient predator.

    What does the term "piscivorous" mean?

    • A Fish That Lives In Salt Water

    • A Person Who Catches Fish

    • A Creature That Eats Fish

    • A Fish That Lives In Fresh Water

    Correct Answer
    A. A Creature That Eats Fish
    Explanation
    The term "piscivorous" refers to a creature that eats fish. This term is used to describe animals that have a diet primarily consisting of fish. It does not specify whether the fish lives in saltwater or freshwater, nor does it refer to a person who catches fish. The term specifically pertains to the eating habits of a creature.

    Which of these plant cell parts functions as a storage spot?

    • Vacuole

    • Nucleus

    • Cell Membrane

    • Cell Wall

    Correct Answer
    A. Vacuole
    Explanation
    The vacuole functions as a storage spot in a plant cell. It is a large, membrane-bound organelle that stores water, nutrients, and waste products. The vacuole helps maintain the cell's shape and rigidity by regulating the water content and pressure within the cell. Additionally, it stores various molecules, such as pigments, toxins, and defense compounds. The vacuole also plays a role in breaking down and recycling cellular waste materials. Overall, the vacuole is an essential organelle for maintaining the overall functionality and homeostasis of the plant cell.

    How many chromosomes does a typical human body cell have?

    • 46

    • 23

    • 100

    • 2

    Correct Answer
    A. 46
    Explanation
    A typical human body cell has 46 chromosomes. Chromosomes are thread-like structures made of DNA that contain genes, which carry the genetic information necessary for the development and functioning of a living organism. In humans, chromosomes come in pairs, with each pair consisting of one chromosome inherited from the mother and one from the father. Therefore, the total number of chromosomes in a human body cell is 46.

    Which of these parts is not part of a leaf?

    • Blade

    • Stoma

    • Vein

    • Hair

    Correct Answer
    A. Hair
    Explanation
    Hair is not part of a leaf. Leaves typically consist of a blade (the flat, green part), stomata (small openings for gas exchange), and veins (vascular tissue for transporting water and nutrients). Hair, on the other hand, is not a structural component of a leaf and does not play a role in its functioning.

    What makes up most of dust particles found in a house?

    • Cotton

    • Paper Particles

    • Dead Skin

    • Bug Feces

    Correct Answer
    A. Dead Skin
    Explanation
    Dead skin makes up most of the dust particles found in a house. As humans shed dead skin cells continuously, these cells become airborne and settle on surfaces, contributing to the accumulation of dust. Dead skin is a common component of household dust and can be found in various areas of the house, including furniture, floors, and bedding.

    Where does the Krebs Cycle occur in humans?

    • Lysosome

    • Cytoplasm

    • Golgi Bodies

    • Mitochondrial Matrix

    Correct Answer
    A. Mitochondrial Matrix
    Explanation
    The Krebs Cycle, also known as the citric acid cycle, occurs in the mitochondrial matrix in humans. This is where the series of chemical reactions take place to generate energy for the cell. The mitochondrial matrix is the innermost compartment of the mitochondria and is rich in enzymes that are necessary for the Krebs Cycle to occur. This process plays a crucial role in the metabolism of carbohydrates, fats, and proteins, and is an essential part of cellular respiration.

    In what part of the body is hair growth the fastest?

    • Scalp

    • Legs

    • Chest

    • Face

    Correct Answer
    A. Face
    Explanation
    Hair growth is the fastest on the face. This is because the hair follicles on the face have a shorter growth phase compared to other parts of the body. The growth phase, known as the anagen phase, determines how long the hair will grow before it falls out. In the case of facial hair, the anagen phase is shorter, resulting in faster hair growth compared to other areas such as the scalp, legs, or chest.
