Neuron is a cell of the nervous system that is involved in carrying of impulses between the nervous system and the rest of the body. There are three types of neurons namely; relay neuron, motor neuron and the sensory neuron. Neuron is made up of various parts that enhance is activity in transmission of impulses/information which includes, dendrites, cell body, axon, myelin sheath among others. The conduction of information in the neuron starts from the Dendrites, then to the cell body, to axon and then to synapse where a neuron links with another and the process is repeated. Therefore; the correct answer is C
Bird skeletons are very delicate, and therefore, difficult to be preserved. The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.
Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).
