The coxal joint is most likely found in _______ region of the body.
hip
foot
hand
groin
The Correct Answer is A
A. Hip: The coxal joint, also known as the hip joint, is the articulation between the head of the femur and the acetabulum of the pelvic bone. It is a ball-and-socket joint that provides stability and mobility.
B. Foot: The foot contains joints such as the tarsal, metatarsal, and phalangeal joints, which allow for movement and weight bearing. However, none of these are referred to as the coxal joint.
C. Hand: The hand has numerous joints including carpals, metacarpals, and phalanges. These joints support fine motor skills but are not associated with the coxal joint.
D. Groin: The groin is the area where the thigh meets the lower abdomen. Although anatomically close to the hip region, the coxal joint itself is specifically part of the hip rather than the groin.

Correct Answer is C
Explanation
A. Chloride ions: Chloride ions help stabilize the membrane potential by balancing charges, but they move passively along gradients set by other ions. Since chloride permeability is not the dominant factor at rest, they do not primarily determine the resting membrane potential.
B. Calcium ions: Calcium concentration is kept very low inside cells compared to outside. Its main role is in processes like muscle contraction and neurotransmitter release, rather than in establishing the electrical gradient at rest, so it contributes little to resting potential.
C. Potassium ions: Potassium ions are the major determinant of resting membrane potential because the membrane is most permeable to potassium at rest. Efflux of potassium through leak channels leaves the inside more negative, making it the primary driver of resting potential.
D. Sodium ions: Sodium ions are more concentrated outside the cell and tend to diffuse inward, but the membrane has low sodium permeability at rest. Although sodium influx is important during depolarization, it is not the chief factor in establishing resting membrane potential.
Correct Answer is A
Explanation
A. They appear to be the molecular carriers of coded hereditary information: Proteins are not the carriers of hereditary information; that role belongs to nucleic acids like DNA and RNA. Proteins are synthesized based on genetic instructions, but they do not store genetic code themselves.
B. Their function depends on their three-dimensional shape: The specific three-dimensional conformation of a protein determines its functional properties, such as enzyme activity or receptor binding, making shape critical for proper function.
C. They may be denatured by heat or acidity: Proteins can lose their structure and function when exposed to extreme heat or changes in pH. Denaturation disrupts hydrogen and ionic bonds, altering the protein’s shape and activity.
D. They have both functional and structural roles in the body: Proteins serve multiple roles, including structural functions in connective tissues and functional roles such as enzymes, hormones, and antibodies, supporting diverse physiological processes.
