    Correct Answer
    A. Water
    Explanation
    In photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. Water is the source of oxygen in photosynthesis. During the light-dependent reactions of photosynthesis, water molecules are split, releasing oxygen as a byproduct. This oxygen is then released into the atmosphere, while the hydrogen atoms from water are used to generate energy and produce glucose. Therefore, water serves as the source of oxygen in photosynthesis.

    Rate this question:

  • 27. 

    Wind energy is the __________ energy.   Kinetic energy?

    • Amino acids

    • Vitamin

    • DNA

    • Water

    Correct Answer
    A. DNA
    Explanation
    Mitochondria contain their own supply of DNA. This is because mitochondria are considered the "powerhouses" of the cell and are responsible for producing energy through a process called cellular respiration. They have their own set of DNA, known as mitochondrial DNA (mtDNA), which is separate from the DNA found in the cell's nucleus. This mtDNA is essential for the production of proteins and enzymes needed for energy production.

    Rate this question:

  • 30. 

     Mitochondria are called the powerhouses of the cell. 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Mitochondria are called the powerhouses of the cell because they are responsible for producing the majority of the cell's energy in the form of adenosine triphosphate (ATP) through the process of cellular respiration. They contain their own DNA and can replicate independently, suggesting that they were once free-living organisms that formed a symbiotic relationship with eukaryotic cells. This unique ability to generate energy makes mitochondria essential for the functioning of cells and is why they are often referred to as the powerhouses of the cell.

    A. Skin
    Explanation
    The production of sweat and sebum is related to the skin. Sweat is produced by sweat glands in the skin and helps regulate body temperature by cooling the body through evaporation. Sebum is an oily substance produced by sebaceous glands in the skin and helps moisturize and protect the skin. Therefore, the correct answer is skin.

    Rate this question:

  • 39. 

    Proteins are made from amino acids by the process of.....?

    • Hydrolysis dehydration synthesis

    • active transport

    • Pinocytosis

    • Hydroysis

    Correct Answer
    A. Hydrolysis dehydration synthesis
    Explanation
    Proteins are made from amino acids by the process of dehydration synthesis. In this process, two amino acids are joined together by removing a water molecule. This reaction occurs repeatedly to form a long chain of amino acids, which then folds into a protein. Hydrolysis, on the other hand, is the opposite process where proteins are broken down into amino acids by adding a water molecule. Therefore, dehydration synthesis is the correct answer as it describes the process of building proteins from amino acids.
