QUICK ANSWERNatural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve. If a group of people have predominantly brown hair genes and have children, then by way of natural selection the dominant gene will increase with future generations, meaning that slowly in time this group of people will evolve to have mostly brown hair genes
Carrying Capacity. For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources. Reproductive lag time may cause the population to overshoot the carrying capacity temporarily.
If you are talking about the amount of material, it will be equivalent. But monomers are usually smaller than polymers.
freeze-thaw, and exfoliation
Sensory neurons
Process
Light falls onto retina. The retina generates an impulse that is carried to the brain by the sensory neurons. An impulse is not carried by blood vessels, so that crosses out A. A muscle cant carry impulses either. Spinal cord isnt the answer because it doesnt have to go through the spine because the eye and brain is so close together
