C LaMarck believed that over time, shorter giraffes were starved out and giraffes with longer necks survived to reproduce. Various views explaining how evolution takes place have been proposed by scientists across the decades. C examining homologous structures in fossil remains The cheetah is one of the fastest animals on the planet.

A In most primates the inability to move the ear has been replaced by the ability to turn the head on a horizontal plane as well as having peripheral vision. Which term is used to describe this phenomenon?

What conclusion can be drawn? B The finches have always had different beak sizes and that has never changed throughout time. These resistant forms are the ones to survive, reproduce, and pass on their genes.

Mesohippus was about two feet tall, ran on hooves with three toes, and had large, grinding teeth. Darwin helped pave the way to showing that organisms do change over time, and it is due to the slight changes found within the population.

D Tortoises who used their shells in special ways caused the shells to become larger, rounder, or flatter. Horses are now much larger. C The area once had a warmer climate. This allows sodium to pour into the cell continuously, causing the nerve to fire repeatedly and eventually leading to paralysis.

C It would strengthen the theory, because of the clear connection between being a blacksmith and having certain physical traits.

One other answer is a true statement; it just does not answer the question. Mosses and liverworts, non-vascular plants, are the least evolved plants, and must remain near water, because they cannot 'wick' water up Natalie hall dating stems.

This acquired trait of a long neck was inherited by their offspring, and thus all giraffes now have long necks. Based on the data given, choose the BEST conclusion.

D inheritance of acquired characteristics. Today however, there are a multitude of antibiotic resistant bacterial infections. C Traits cannot be chosen willfully, but are randomly inherited from our parents. B Most primates are not victims of predators and they are not predators themselves so they do not need this trait.

Percentages are based on environmental pressures. Mesohippus lived in North America about 40 million years ago. They will pass this resistance to their off-spring. What does this suggest about this area in Alaska? These compounds work by attacking the nervous system.

B Antibiotics cause DNA mutations in bacteria, and over time, this has led to resistance. From the pervading sense of vulnerability surrounding Ebola to the visibility into acts of crime or misconduct that ignited critical conversations about race, gender, and violence, various senses of exposure were out in the open this year.

Darwin reasoned that the particular shape of the shell was related to the ability of the tortoise to survive and reproduce. Which of these would be an example of how someone would explain why the finches had different beak sizes PRIOR to the ideas developed by Darwin?

Here's an excerpt from our announcement in C The size and shape of the beaks differed because of the effects of artificial selection. The mutations are favored when a population of organisms winds up in an environment in which the mutations happen to be useful.

D It would weaken it, because it suggests that development of some traits may not be linked to the characteristics of one's parents. This is the best answer because it directly refutes Lamarck's claim, that acquired traits are passed down from parents to children.
