Lelechka [254]

Answer:

The correct answer is option B.  The contraction forces of the innervated muscle fibers.

Explanation:

Electromyography or EMG is the study of muscle activity with the help of analyzing electric signals that are burst or generated by the contraction of the muscle fibers. In other words, it is the electrical activity of the skeletal muscles in response to a nerve's stimulation of the muscle.

EMG uses the myoelectric signals to analyze muscle that is generated during the contraction forces of the inverted muscle fibers of the skeletal muscle.

Thus, the correct answer is option B.  The contraction forces of the innervated muscle fibers.

A particular gene has two alleles, a dominant allele A and a recessive allele a. The frequency of allele A is 0.55. If the popul
bezimeni [28]

If p = frequency of A and q = frequency of a, then assuming H-W equilibrium we have

p + q = 1   ⇒   q = 1 - p = 1 - 0.55 = 0.45

Then the expected frequency of the heterozygous genotype Aa is 2pq = 2 • 0.55 • 0.45 = 0.495.

The ______ is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the _______ joint.
Setler [38]

The acetabulum is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the coxal joint.

The acetabulum is made up of the three bones that make up the coxal bone (hip bone).

The ischium, which offers the lower and side limits to the acetabulum, makes up somewhat more than two-fifths of the structure.

Less than two-fifths of the acetabulum's structure is provided by the ilium, which also serves as the top limit of the joint.

The pubis, which is close to the midline, forms the remainder.

The acetabulofemoral joint (art. coxae), also known as the coxal joint, is the joint between the head of the femur and the acetabulum of the pelvis.

Its main job is to support the weight of the body in both static (such as while standing) and dynamic (such as when walking or running) postures.
