Answer:During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. ... During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase.
Explanation:
The name of the structure labeled as A is 'myosin'. Moreover, the name of the structure labeled as B is 'actin'.
A sarcomere is the basic unit of muscle contraction. This unit is defined as the region between two Z-lines.
Band A is a central band composed of the thick filaments of myosin.
Moreover, the sarcomere also has two halves of a band known as I-band, which consists of thin filaments of actin.
Muscle contraction is caused by the interaction between actin and myosin protein filaments in the sarcomeres.

An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.
Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.
