_________ glands secrete a mixture of disintegrated cells and their products.

A. bind the hair root to the dermis:The hair root is anchored to the dermis by the hair follicle itself and connective tissue structures. The receptor does not play a role in binding or physical attachment of the hair root.

B. serve as a source for new epidermal cells for hair growth after the resting stage has passed:New epidermal cells for hair growth arise from the hair matrix at the base of the follicle. The root hair plexus is a sensory nerve ending, not a cell-generating structure.

C. allow the hair to assist in touch sensation:The hair follicle receptor, or root hair plexus, is a network of sensory nerve endings wrapped around the follicle. It detects movement of the hair, making hair an important component of the tactile sensory system.

D. cause apocrine gland secretion into the hair follicle:Apocrine gland secretion is controlled by hormonal and neural signals, but not by the root hair plexus. The plexus functions in sensation, not glandular stimulation.

A. late prophase:During late prophase, chromosomes condense and the mitotic spindle forms, but cytokinesis has not yet begun as the cell is still preparing for chromosome alignment.

B. early anaphase:Early anaphase involves the separation of sister chromatids toward opposite poles. Cytokinesis does not start at this point because chromosome separation is still in progress.

C. early prophase:Early prophase is the initial stage of mitosis where chromatin condenses into visible chromosomes. Cytokinesis is not initiated at this stage.

D. late anaphase:Cytokinesis begins during late anaphase, when the cell starts forming a cleavage furrow as the chromosomes near the poles. This process continues into telophase, ultimately dividing the cytoplasm into two daughter cells.
