The image below shows one muscle cell. Please choose the name of the structure that is labeled A.
Bond [772]

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.

Why are lipids important as food molecules?
olga nikolaevna [1]

Look at metaphase and anaphase. Suggest the purpose of the spindle fibers during mitosis.
guajiro [1.7K]

Answer:

The spindle fibre is necessary to separate the sister chromatids into opposite sides of the cell.

Please find detailed explanation below

Explanation:

Mitosis is the cell division that produces two daughter cells that are genetically identical to the parent cell. Mitosis occurs in stages viz: prophase, metaphase, anaphase and telophase. The replicated chromosome, aligns at the centre of the cell in the METAPHASE stage and separates into opposite poles in the ANAPHASE stage.

This alignment (at the equator) and separation into opposite pole is possible with the aid of a structure called SPINDLE FIBRES. Spindle is a structure formed from microtubules, which attach to the kinetochores (located in the centromere) of each replicated chromosome to separate them from one another. Hence, the purpose of the spindle fibre during mitotic division is to separate the GENETIC MATERIAL of a parent cell into two daughter cells.
