Which statement explains why the two populations are no longer able to mate with each other?, The salamanders in one population have a different diet, which prevents the populations from mating., The salamanders with genes for greater physical strength are no longer able to mate with salamanders without genes for greater physical strength., The salamanders that survived a bottleneck event passed on to the next generation more genes that no longer allow the populations to mate., Why would all polar bears have identical APOB genes?, The bears that carried that particular APOB sequence were better adapted to cold Arctic conditions and had a higher chance of passing their genes to the next generation., The bears that carried that particular APOB sequence were better adapted to cold Arctic conditions and had an equal chance of passing their genes to the next generation., The bears that carried that particular APOB sequence were better adapted to cold Arctic conditions and had a lower chance of passing their genes to the next generation., The picture shows three families of rabbits. Which statement best explains how the picture shows offspring inherit their parents? ment, The babies have the same fur color as their father.her, The babies have the same fur color as their mother, The babies can have different fur patterns than their parents. , The babies have the same fur colors as one or both of their parents. , ?What does this show about the population of the village, The population of the village was more likely to catch the disease than the larger population., The population of the village had genetic diversity since some people avoided catching the disease, The members of the population of the village who avoided catching the disease were more evolved than others., How does crossing over result in inheritable genetic variation?.Scientists are studying genetic variation in a common mustard plant. They find that one chromosome has an average of 1.6 crossing-over events per meiosis. The model shows the process of crossing-over. Alleles Q and T appear on the same chromosome., There are fewer allele combinations after crossing-over, decreasing genetic variation., New combinations of alleles increase the genetic variation passed down during meiosis, Cells experiencing crossing-over cannot pass these changes to their offspring during meiosis., What conclusion can be made about these animals as embryos and adults?.Students are comparing the development of five different species of animal. The embryos of five different species are shown during three stages of development., All five species look different from the beginning of development., All five species have different adult features at the beginning of development., All five species gain specific adult features as they go through the stages of development., ?Which statement best describes the role of limited resources in the evolution of traits within a population, Traits that enable individuals to better compete for resources may become more common over multiple generations., Individuals with the same genetic traits will mate and produce individuals with different traits to compete for limited resources, Individuals who obtain resources using strategies they have learned will live longer and pass these traits to the next generation, Students are studying the process of mitosis. The model shows a cell before and after DNA replication as it prepares for mitosis.Which two statements accurately describe the end product when this cell completes mitosis?, Mitosis will produce cells that are diploid, There will be two cells when mitosis is finished, The cell will divide in half twice during the process..
