They are thread-like structures on the surfave of roots that absorb water and nutrients.
The number of phenotypes produced for a given trait depends on the number of genes that control that trait. so the answer is 1
Our interconnected neurons help us process different types of information. Synapses are the gaps between neurons. <span>When an impulse reaches the end of one axon, it is now an action potential.
