Genes, which are segments of DNA, carry the information for specific traits or characteristics. Therefore, the correct answer is genes.

    What is the pH of lemon juice?

    • A.

      4-5

    • B.

      3

    • C.

      6

    Correct Answer
    B. 3
    Explanation
    Lemon juice has a pH of 3, making it acidic. The pH scale ranges from 0 to 14, with 0 being the most acidic and 14 being the most alkaline. A pH of 3 indicates that lemon juice is highly acidic, which is why it has a sour taste. The acidity of lemon juice is due to the presence of citric acid, which gives it its characteristic flavor and pH level.

Loop refers to a pattern where ridges enter from one side of the finger and exit from the same side. Arch refers to a pattern where ridges enter from one side and exit from the other side, forming a wave-like shape. These three patterns are commonly used in fingerprint identification and classification.
