<span>1) It is the chromosomes, however, that assort independently, not individual genes.
2) </span> <span>It tells you they're really far apart.
You see, there's this phenomenon called crossing over. Chunks of DNA get randomly swapped between homologous chromosomes. If two genes are close together they're usually swapped together and if they're far apart (say, on opposite ends) they're probably never going to be swapped together because half a chromosome doesn't normally cross over at once.

3) <span>Sexual reproduction, because it results in offspring that combine alleles from two different individuals. </span>
<span>(Crossover is fine and dandy and you should mention it, but you'd get a C if you didn't mention that two different individuals are contributing genetic material to the offspring)</span>

More biodiversity often means a more stable food web as their is more to fall back on
Facilitated diffusion occurs with the help of a transport protein, such as electrons passing through ATP synthase in the electron transport chain.
it's (+/-) 90 degrees. in total it's 180 but the equator is at zero and the two hemispheres have 90 each
The ganglia are formed from the cell bodies of a group of neurons. The ANS or autonomic nervous system associates with the CNS (central nervous system) and the somatic nervous system with the help of ganglia. The ganglia accommodate the cell bodies of sensory (afferent) and motor (efferent) cell bodies of the ANS.
The sympathetic ganglia are situated near to the central nervous system. The two sympathetic ganglia, which locate the cell bodies of post-ganglionic cell bodies are sympathetic trunk ganglia (situated alongside the vertebral column) and collateral ganglia (anterior to the vertebral ganglia).
