As the experts says, solar eclipse do not happen always like lunar
eclipses do that is visible for a long periods of time and are observable. Unlike
solar eclipse, it happens hundreds and thousands of years to see it. Few people
can only see solar eclipse, and those only those people
who are in the small region where the Moon's umbra strike's Earth can witness
one.
Deconstructionism is not a component of balanced and restorative justice model.
Balanced and restorative justice is termed as the theoretical model and attempts to span tension between treatment and retribution. In this process victims takes an active role. Offenders take full responsibility for their actions.
Seize an opportunity to do right from wrong and redeem themselves before their community and before their eyes. Restorative justice focuses on helping offenders from future offences.
Answer:
Mitosis is used to produce daughter cells that are genetically identical to the parent cells.
Explanation:
The cell copies its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
Striated muscles contain repeating sarcomeres of overlapping arrays of long, thin actin and thicker myosin filaments. Myosin filaments contains the myosin heads, which are enzymes that can bind to actin, split and make use of the energy from ATP. When muscle contraction starts, myosin heads bind to actin, change their configuration on actin, liberating the products of ATP hydrolysis and causing slide of the actin and myosin filaments. The action of the proteins troponin and tropomyosin on the actin filaments regulates vertebrae striated muscle contraction. The release of calcium ions from the sarcoplasmic reticulum is triggered by the nervous stimulation which causes depolarization of muscle membrane. Calcium ions bind to troponin and thus cause or allow the tropomyosin strands on the actin filament to move so that the part of the actin surface where myosin heads need to bind is uncovered. Contraction then occurs and only stops when the sarcoplasmic reticulum pumps calcium out of the muscle interior.
So basically, what triggers the uncovering of the myosin binding site on actin is the calcium ions binding to troponin and changing configuration.
