    Living things need _______________________ to grow, move, and survive

    • Kingdoms

    • Energy

    • Bacteria

    • Taco bell

    Correct Answer
    A. Energy
    Explanation
    Living things need energy to grow, move, and survive. Energy is required for all the metabolic processes in living organisms, such as cellular respiration, digestion, and synthesis of molecules. It is obtained through the consumption of food or sunlight in the case of plants. Energy is then converted and used by cells to perform various functions necessary for the survival and growth of living organisms. Without energy, living things would not be able to carry out essential processes and would ultimately cease to exist.

    Bacteria are single _____________ without nuclei

    • Producers

    • Cells

    • Parasites

    • Archaea

    Correct Answer
    A. Cells
    Explanation
    Bacteria are single cells without nuclei. This means that they are unicellular organisms that lack a defined nucleus within their cell structure. Bacteria are classified as prokaryotes, which are organisms that do not have membrane-bound organelles or a true nucleus. Instead, their genetic material is found in a region called the nucleoid. Therefore, the correct answer is cells.

  • 6. 

    Bacteria that break down material

    • Decomposers

    • Producers

    • Consumers

    • Harmful

    Correct Answer
    A. Decomposers
    Explanation
    Decomposers are organisms, such as bacteria, that break down organic material into simpler substances. They play a crucial role in the ecosystem by breaking down dead plants and animals, as well as waste products, and recycling nutrients back into the environment. Decomposers are responsible for the process of decomposition, which helps to release nutrients and energy that can be used by other organisms. Unlike producers, which create their own food through photosynthesis, decomposers obtain their energy by breaking down organic matter. Consumers, on the other hand, obtain their energy by consuming other organisms. Therefore, decomposers are the most appropriate answer for bacteria that break down material.

    Rate this question:

  • 7. 

    Bacteria that live in or on an organism and harm their host

    • Consumer

    • Archaea

    • Decomposers

    • Parasites

    Correct Answer
    A. Parasites
    Explanation
    Parasites are organisms that live in or on another organism and harm their host. They rely on the host for their survival and obtain nutrients from the host's body, often causing damage or disease in the process. Unlike decomposers that break down dead organic matter, parasites actively feed on living organisms. This relationship is detrimental to the host, as the parasites benefit at the expense of their host's health and well-being.

    A _______________ is not a living thing, even though it has genetic material

    • Zombie

    • Microorganism

    • Bacteria

    • Virus

    Correct Answer
    A. Virus
    Explanation
    A virus is not a living thing, even though it has genetic material because it lacks the ability to reproduce and carry out metabolic processes on its own. It can only replicate by infecting a host cell and using the host's cellular machinery to reproduce. Viruses are considered to be on the border between living and non-living entities because they possess genetic material like living organisms, but they lack the necessary characteristics to be classified as living organisms.

    All living things ____________________.  they consume food and other materials.

    • Dance

    • Breathe

    • Grow

    • Relax

    Correct Answer
    A. Grow
    Explanation
    Living things grow because they undergo a process of increasing in size or developing physically. This growth is fueled by the consumption of food and other materials, which provide the necessary nutrients and energy for the organism to grow. Therefore, the ability to grow is a characteristic shared by all living things.

    Material from one cell is divided into two cells

    • Meiosis

    • DNA

    • Binary fission

    • Photosynthesis

    Correct Answer
    A. Binary fission
    Explanation
    Binary fission is the correct answer because it is a form of reproduction in single-celled organisms where one cell divides into two identical daughter cells. This process is commonly observed in prokaryotes like bacteria. Meiosis, on the other hand, is a type of cell division that occurs in eukaryotic organisms and results in the formation of gametes. DNA is the genetic material found in all living organisms, and photosynthesis is the process by which plants convert sunlight into energy.

    Bacteria that transform energy that can be used by cells

    • Decomposer

    • Consumer

    • Producers

    • Robots

    Correct Answer
    A. Producers
    Explanation
    Producers are organisms, such as plants, that have the ability to transform energy from the sun into a form that can be used by cells. They do this through the process of photosynthesis, where they convert sunlight, water, and carbon dioxide into glucose and oxygen. This energy-rich glucose is then used by the cells of the producers themselves or consumed by other organisms in the food chain. Therefore, the statement "bacteria that transform energy that can be used by cells" aligns with the characteristics of producers.
