Which of the following is exchanged between two or more atoms that undergo ionic bonding?

A. Neutrons

B. Transitory electrons

C. Valence electrons

D. Electrical charges

Answer Explanation:

An ionic bond forms when one atom donates an electron from its outer shell, called a valence electron, to another atom to form two oppositely charged atoms.

Therefore, the Correct Answer is C.

  • Q #1: Which of the following anatomical terms is NOT part of the knee?

    A. Medial collateral ligament

    B. Patella

    C. Lateral malleolus

    D. Lateral meniscus

    Answer Explanation

    The term "lateral malleolus" refers to the bony prominence on the outer side of the ankle.

    It is part of the ankle joint, not the knee joint. The other options, such as the medial collateral ligament, patella, and lateral meniscus, are all associated with the knee joint.

  • Q #2: Which of the following does NOT obey the law of independent assortment?

    A. Two genes next to each other on a chromosome

    B. Two genes on opposite ends of a chromosome

    C. Flower color and height in snapdragons

    D. Seed color and flower color in peas

    Answer Explanation

    Two genes next to each other (or within a specified close distance) are said to be linked. Linked genes do not follow the law of Independent assortment because they are too close together to be segregated from each other in meiosis.

  • Q #3: What type of mutation is represented by the following sequence? Original: 123456 Mutated: 154326

    A. Breakage

    B. Deletion

    C. Insertion

    D. Inversion

    Answer Explanation

    An inversion mutation is represented in the sequence 1 5 4 3 2 6. An inversion error is a type of mutation where an entire sequence of DNA is reversed. In this case, 2 3 4 5 has been reversed to 5 4 3 2.

    Breakage, choice A, in a gene can mess up its function entirely or lead to a translocation of genetic information. Choice B, deletion, is when a section of DNA is omitted or lost.

    Choice C, Insertion, is when an extra base pair is added to a DNA sequence. Deletions and insertions can lead to a frameshift effect where entire sequences are thrown off because one nucleotide is wrong.

    This could result in coding for the wrong amino acid and non-functioning proteins.
