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.
Because the roots take in the water from the soil and spreading it out evenly through out the plant leaves and such

Answer:
The correct answer is B 4 cells are formed,each having half the number of chromosomes as the original cell.
Explanation:
Meiosis is a specific type of cell division that occur in the germ cells.Meiosis is called reductional division because the 4 new cells those are produced after second meiotic division contain half the number of chromosomes as that of original cells.
During meiosis a cell undergo division two times the division that occur during first time is called first meiotic division resulting in the formation of 2 cells having 2n number of chromosomes.On the other hand the second meiotic division form 4 cells each having half the number of chromosomes.
