Answer:
Muscles at the microscopic level are made of actin (thin filament) and myosin (thick filament) fibers in alternation and parallel to each other. During contraction, the fibres seem to slip against each other in opposite directions. Technically, the myosin head ‘walks’ on the actin – in an engage and release motion – with the help of ATP. Several actin and myosin fibers make up a myofibril. Each contractile unit in the myofibril is called a sarcomere – viewed as Z-discs at the microscopic level.
Answer:
D. H+
Explanation:
hydrogen protons are found in water
a process called protolysis occurs where water molecules exchange protons with each other
The best-characterized examples of multiple alleles in humans is the ABO blood groups, discussed in the Non-Mendelian inheritance concepts. Other human traits determined by multiple alleles would be hair color, hair texture, eye color, built, physical structure, etc.
