Select the statement that is most correct. a. The dorsal root ganglion is a motor-only structure. b. The cell bodies of afferent
ganglia are located in the spinal cord. c. Ganglia are collections of neuron cell bodies in the spinal cord that are associated with efferent fibers. d. Ganglia associated with afferent nerve fibers contain cell bodies of sensory neurons.
The most correct statement is d. Ganglia associated with afferent nerve fibers contain cell bodies of sensory neurons.
Explanation:
Ganglia are considered a group of nerve cell bodies and are responsible for carrying nerve impulses. The sensory nerve ganglion collects and modulates the sensory information, and constitutes the deposits of the neuronal somas of the primary afferent fibers of the sensory system. This consists of afferent nerve cell bodies, efferent nerve cell bodies, and neuronal axons. It acts by receiving signals from the periphery and sending them to the brain, that is, it has an afferent function. Afferent fibers transmit sensory stimuli from the skin, mucous membranes and deep structures, for this, ganglia are constituted by abundant distinctive neuronal connections, which are responsible for receiving these signals and fulfilling their afferent function.
Energy stored in food can be used by cells to add a phosphate group to ADP to make ATP. This cycling of ATP to ADP occurs in a metabolic process called cellular respiration. phosphate group breaks, and energy is released. ATP becomes ADP, and the cycle of storing and releasing energy continues until the cell dies.
Answer: They should be able to have access and deal with food distributed homogeneously in 360 degreea
Explanation:
This is because radially symmetrical animals meet their environment equally from every sides or angle e.g sessile while Bilateral symmetrical animals can move actively in only horizontal direction, so that they can eat. E.g Arthropods
