Because so much of each species genome is the same, Campagna says its easier to find the minute differences, making them great subjects for study. Using one of these four ideas, explain why you do not look like another person in this room. Privacy Policy. Humans share common biological constraints b. The differences consistently fell in areas near color genes in sections of the genome once considered junk. Scientists have since learned that these areas of the genome, which once appeared to have no purpose, can play crucial roles in regulating genes and modifying their effects. If mutations arise that affect shell thickness within a snail population, then with crabs present, those mutations:Will result in offspring having thicker shells than their parents.Will result in offspring having thicker or thinner shells than their parents.Will happen because the parents choose to give them to their offspring.Will occur because crabs are present and snails need protection against predation.Q6.4. c) Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring.

Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. Why or why not? For example, when humans first migrated to North America, they were faced with a new environment with different plants and animals. Nam risus ante, dapibus a molestie consequat, ultrices ac magna. This is a question that has been debated for many years. Some populations are innately superior to others, because they have what it takes to prevail in those environments. So we've already got in one year we've already got nearly a sixth of these people dying of this number of people dying. Some force other than environmental conditions must be acting upon the males to produce so many species. O No, species do not change even after many generations, so individuals of the same species would not look different. A species is a population of plants or animals that can breed to produce offspring that can then produce offspring themselves. There is some debate over whether individuals or the population adapt to change. Explain why the visual perceptions that other animal have and why that sensory input would vary and be differ from our own vertebrate visual system.

It occurs when groups in a species become reproductively isolated and diverge. A food source must disappear. (EQ: 9, 13) Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring. Why are there such large differences in the diversity within a clade? Many years ago, more than 13 different species of birds migrated to the islands. The descendants would look the same as the original individuals because species do not change. For example, if a species of fish was only exposed to freshwater, they might look different than if they were exposed to saltwater. Could individuals of a species look different today chegg.

Question: Q6.4. why or why not? Our experts can answer your tough homework and study questions. B. Proponents of the adaptation argument argue that individuals adjust and adapt to new situations and conditions, while opponents argue that the population as a whole adapts, which can lead to unforeseen consequences. Could individuals of a species look different today than individuals of the same species did many generations ago? 2 years ago, Posted Genotype is the written instructions for appearance based on the DNA. Numerous species in the same region must have recently become extinct. Explanation: Species evolve over time scales/generations, and individuals that possess traits that are advantageous in the current environment can live at a higher frequency and transfer those advantageous traits on to their offspring.

When we adapt, or evolve over time, does it happen through genetic mutation or something different? Scientists have estimated that there are around 8.7 million species of plants and animals in existence. Why does diversity between individuals and between species create problems for determining what is a species and what is a variant? Why are humans so different from other animals? Yes, some individuals with certain traits are more likely to survive and pass those traits on to their offspring.
