The hip is an example of which of the following type of joints?

A. Ball-and-socket

B. Pivot

C. Gliding

D. Hinge

Answer Explanation:

The hip joint is an example of a ball-and-socket joint. The hip joint is formed by the articulation of the head of the femur with the acetabulum of the pelvis. The rounded head of the femur (ball) fits into the cup-shaped acetabulum (socket), allowing for a wide range of motion in multiple planes.

Therefore, the Correct Answer is A.

  • Q #2: A strand of DNA bases reads 5' AGCTAGCGT 3, what would the sequence of bases on the contemporary strand read?

    A. 3' STOGUTCGCU

    B. 5' AGCTAGCGT S

    C. 3' SUCGAUCICA

    D. 3' TCGATCGCA 5'

    Answer Explanation

    The complementary strand of DNA is formed by pairing complementary bases. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). Additionally, RNA uses uracil (U) instead of thymine.

    Given the sequence 5' AGCTAGCGT 3', the complementary strand would read:

    3' TCGATCGCA 5'
