<span>Proteins are different based on number and type of ____________ contained in their polypeptide chain(s)

Like DNA, RNA polymers are make up of chains of nucleotides. The sugars they are made up of; a five carbon ribose sugar.
Or Pentose Sugar.
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
Answer:
rocks
Explanation:
A geologist is a person who studies the rocks and the earth's surface to find different phenomenon. The study of rocks and he fossils found there helps the geologist to understand and conclude the type of climate and the environment it formed the fossils of a place on earth. It provides large amount of information about the climatic conditions of the place when the layer of it was forming.
<span>Postsynaptic potentials are changes in the membrane potential of postsynaptic terminal. A depolarizing synaptic potential is also known as an excitatory postsynaptic potential. it is the synaptic potential that makes postsynaptic neuron likely to fire an action potential. Postsynaptic neuron is of two forms excitatory and inhibitory.</span>
