Answer: A neuron has three main parts: dendrites, an axon, and a cell body or soma , which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells. Dendrites branch as they move towards their tips, just like tree branches do, and they even have leaf-like structures on them called spines.
The axon (tree roots) is the output structure of the neuron; when a neuron wants to talk to another neuron, it sends an electrical message called an action potential throughout the entire axon.
The features of neurons help them to carry out their function efficiently:
they have a long fibre (axon) so they can carry messages up and down the body over long distances
in a stimulated neuron, an electrical nerve impulse passes along the axon
the axon is insulated by a fatty (myelin) sheath - the fatty sheath increases the speed of the nerve impulses along the neuron
at each end of the neuron are tiny branches (dendrons), which branch even further into dendrites - the dendrites receive incoming nerve impulses from other neurons

Answer:
Osteon
Explanation:
Bone tissue may be of two types; compact bone tissue that form the outer hard covering of bones and spongy bone tissue that form inner soft portion of bone. Osteon are found in compact bone.
Osteons are cylindrical structures composed from clustre of Osteocytes and layers of extracellular matrix around a central canal connected by canaliculi for the transportation of blood. The haversian canal is surrounded by lamella that comprises the osteon. Osteons run parallel to long axis of bones and present in bones of many mammals, reptiles and birds. In some bones the stress or pressure in applied from few directions and osteons are aligned in that direction so they provide protection from bone bending or fracturing from compressive forces.

Answer:
The correct answer is d.non-vascular plants with a dominant gametophyte.
Explanation:
Bryophytes are non-vascular plants that present a reduced and not constantly present sporophyte, also their gametophyte is very dominant and is, basically, the whole structure. Their sporophyte only grows when they're reproducing and they disappear when the spores are spread.
