What event at letter b leads to elongation of the bone?
liraira [26]

The occasion at letter b leads to elongation of the bone: <u>Ossification </u><u>of the epiphysis of a protracted bone.</u>

<u />

Elongation is defined because the period at the breaking point is expressed as a percent of its authentic duration (i.e. length at relaxation). If a rubber reaches two times its length earlier than breaking its elongation percentage is a hundred%.

Ultimately, elongation--the addition of nucleotides to the brand new DNA strand--starts offevolved after the primer has been brought. Synthesis of the developing strand entails adding nucleotides, one at a time, inside the actual order distinctive by using the authentic (template) strand.

Can a man and women with attached earlobes have a child with free earlobes? Explain?
krok68 [10]
If the theory was real, two parents with ear lobes attached could not have a child with a free earlobe. A offspring from A x A matings are marginally more, but the large numbers of F offspring from A x A matings and A offspring from F x F matings suggest that this is not a single-locus, two-allele trait.

Which component is responsible for initially stimulating a muscle contraction?
Andrei [34K]

Answer:

Option B, electrochemical signals

Explanation:

The first process that initiates the muscle contraction is the binding of calcium ion with troponin protein. After this chemical interaction, the active binding sites of actin gets exposed. After this myosin binds to the actin sites thereby forming a high-energy  head bridge and releasing the pi. Mysosin now goes to a lower energy state by undergoing conformational change. This causes power stroke and actin filament is pulled towards the M-line. Later on the muscle contracts by shortening  sarcomere.

This entire process is an electrochemical process. hence option B is correct.
