Muscle cramps are caused when the muscle takes longer than normal to relax after a contraction. During contraction, the myosin heads attach on their binding sites on the actin filament and pulls on the filament hence shortening the sarcomeres. For the myosin head to release its binding site on the actin filament, ATP attaches to an active site on the myosin and is hydrolyzed to ADP and Pi. This causes relaxation after a contraction cycle. Cramps, therefore, may be due to depletion of ATP molecule in the muscles cells.
Another reason for cramps may be a high amount of calcium in the muscles that bind to troponin on the actin filaments. This exposes the myosin binding sites longer hence promotes the formation of cross-bridge even when the contraction of the muscle is not intended anymore.
Answer:
Explanation: When this study was carried out by Meselson and Stahl, their findings are compatible with the trend expected by semi-conservative analysis, establishing this as the right template. The two parent strands are split as DNA replicates, and each strand acts as a blueprint for a new DNA strand synthesis.
After the first replication, there are two DNA double helices each marked as superscript 14 N slash superscript 15 N. After the second replication, four double helices of DNA are produced. Three of them are marked as 14 N superscript slash 15 N. Two other DNA was marked as 14 N slash superscript 14 N.
Remember that after a round of testing, Meselson and Stahl were able to rule out the moderate template based on the results. At that point, though, they were unable to rule out the dispersive model because that model predicts the same trend as the semiconservative model. But after two trials, the findings made it possible for them to rule out the dispersive design.
Answer:
It was Produced through Sexual Reproduction
Explanation:
This is true because when two members of a species reproduce through meosis the offspring inherents half of the dna from each parent
The answer is No. The analysis concluded that there
is no indication that pain-related fears mediate for reducing disability and pain
in patients with complex regional pain syndrome.
Complex Regional Pain Syndrome (CRPS)
is called as Reflex sympathetic dystrophy<span> (RSD)</span><span>, in this condition you have a pain in arm or leg, which develop
after any injury, surgery, stroke etc. Medical treatment needed in this
condition, may be some medication or physiotherapy.</span>
