The answer is sliding filament.
Muscle fibers are made up of myosin and actin filaments that straddle one another in alternating sequence. The myosin has myosin heads that act on the actin and enable the myofibrils to slide across each other in opposite directions. This causes the muscle to shorten hence contract. This is an energy-requiring process (hence hydrolyses ATP) and also requires calcium ions. In an animation, the myosin would seem to ‘walk’ on the actin filament.
Separate the soil from clay, sand, and silt. Then test each soil to find which is stronger or weak when it’s wet or dry.
Answer:
the moon's gravity increases over the oceans and decreases over the land
Answer:
I believe the answer is D, but not entirely sure. Have a nice day! (Edit: it's acually B sorry)
Explanation:
Answer: amylopectin and glycogen have the same kind of linkages, but glycogen has a higher frequency of αα-1,6'-glycosidic linkages
Explanation:
Amylopectin is one of the two main fraction of starch. It has several repeating units of glucose molecules linked by α-1, 4-glucosidic linkage, but has many side chains attached to the basic chain by α-1, 6-glucosidic linkages
Glycogen, as well, is a branched polysaccharide and resembles amylopectin very much in structure, but glycogen has more glucose residues per molecule and about one-half times as many branching points.
