Explanation:
gene flow is a movement of the genes in or out of population. This movement can be caused by the migration of organisms that reproduce in the populations. Or the movements of the gametes
Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow and the canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply
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

Because evolution occurs when something happens, and the organism needs to adapt. Events aren't fixed, and they're definitely not random either
Millimeters are the answer here friend. hope you have a bugunga day!
