Yes, chromatin is composed of DNA and proteins that condense to form long strands located within the nucleus. These strands contain genetic information that controls cell functions and are organized into structures called chromosomes during cell division.
Hairs are produced within an organ called the hair follicle, which is located in the dermis layer of the skin. Each hair follicle contains the necessary structures for hair growth, such as the root, bulb, and papilla.
The accessory structures of the skin, such as hair follicles, sweat glands, and sebaceous glands, are primarily found in the dermis layer. The dermis lies beneath the epidermis and provides support and nourishment to the skin, housing these structures within its connective tissue. The dermis also contains blood vessels, nerves, and other components that contribute to the skin's functionality.
The two coiled up strands of DNA within a chromosome are called chromatids. During cell division, chromatids separate and are distributed to daughter cells.
Strands of DNA are bundled into structures called chromosomes within a cell. Each chromosome is made up of tightly coiled DNA wrapped around proteins called histones, which help organize and compact the genetic material. In eukaryotic cells, chromosomes are located in the nucleus, while in prokaryotic cells, the DNA is typically found in a region called the nucleoid. During cell division, chromosomes become visible as distinct entities, facilitating the accurate distribution of genetic material to daughter cells.
The force is called tension, which is the force within the hair strands as they are being combed or pulled.
The nucleus hangs by cytoplasmic strands in a spirogyra cell.

Ribosomes are not bacteria. They are microscopic structures containing proteins and strands of RNA. They are located within the cytoplasm of plant and animal cells.
