George on one pair of his chromosomes has STRs of lengths 6 and 7, Stephen (his father) STRs of lengths 3 and 6, and Mary (his m
JulijaS [17]

Answer:

Stephen is not his biological father.

Explanation:

DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.

The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.

Thus, the correct answer is option (a).

The muscles that surround external body openings typically have a ________ fascicle arrangement. parallel convergent pennate cir
HACTEHA [7]
Parallel

In a parallel arrangement, the length of the fascicles runs parallel to the long axis of the muscle. Such muscles are either straplike like the sartorius muscle of the thigh, or spindle shaped with an extended belly, like the biceps brachii muscle of the arm. However, some scientists classify spindle-shaped muscles into a separate class asfusiform muscles.

Pennate

in a pennate pattern, the fascicles are short and they attach obliquely to a central tendon that runs the length of the muscle. Pennate muscles come in three forms:

<span><span>Unipennate, in which the fascicles insert into only one side of the tendon, as in the extensor digitorum longus muscle of the leg. </span><span>Bipennate, in which the fascicles insert into the tendon from opposite sides so the muscle “grain” resembles a feather.
The rectus femoris of the thigh is bipennate. </span><span>Multipennate, which looks like many feathers side by side, with all their quills inserted into one large tendon. The deltoid muscle, which forms the roundness of the shoulder is multipennate.</span></span>
