What was Lamarck s mistake in how new traits and with it new

What was Lamarck s mistake in how new traits (and with it new species) evolve: That traits are passed on from one generation to the next. That traits are acquired by an individual and passed on to its offspring. That male and female traits \"blend\" during fertilization to create new traits in offspring That natural selection acts on traits of a population and not on individual traits. The term phenotype refers to: The physical expression of traits in an individual. Differences in traits of individuals that can only be detected in a laboratory. All genes found on all chromosomes of an organism. All alleles of all individuals of a population. The study of Darwin finches by Peter and Rosemary Grant is an excellent example of natural selection in action, because the data confirms several of CR Darwin\'s principles. Which principle is reflected in the data presented in the graph? The ability of a population to expand is infinite, but the ability of any environment to support populations is always limited. Organisms vary in the traits they express, and this variation affects the ability of individuals to survive and reproduce. Some traits of organisms are heritable and these traits will be passed on from parents to offspring. None of the above. What does the following graph from the Grants\' study of Darwin finches show? That average beak depth is larger after selection. That the frequency of beak depths before and after selection After selection is similar. That more birds with very large beaks exist in the population after selection. That fewer birds with very small beaks were present in the population before selection. Prokaryotes and eukaryotes share many aspects of cell organization except: Only eukaryote cells have mitochondria. Only prokaryotes have mitochondria. Only prokaryotes have a nuclear membrane around the nucleus. Only eukaryotes have a nucleus.
