- What is the difference between homologous and analogous structuresarrow_forwardGive at least 3 examples of higher forms of life that are bilaterally symmetrical. Explain why they are bilaterally symmetrical.arrow_forwardFigure 1.7 Decide if each of the following is an example of inductive or deductive reasoning. All flying birds and insects have wings. Birds and insects flap their wings as they move through the air. Therefore, wings enable flight. Insects generally survive mild winters better than harsh ones. Therefore, insect pests will become more problematic if global temperatures increase. Chromosomes, the carriers of DNAr separate into daughter cells during cell division. Therefore, each daughter cell will have the same chromosome set as the mother cell. Animals as diverse as humans, insects, and wolves all exhibit social behavior. Therefore, social behavior must have an evolutionary advantage.arrow_forward
- Genetic diversity is important for survival in a population as the environment changes. Describe 3 ways that a sexually reproducing animal species achieves genetic variability. Do NOT include mutations in your description.arrow_forwardNow, it is time to put together all the information you learned about the different kingdoms into one concept map. All terms must be included. You may create this concept map however you like. You may use pen and paper or you may choose to use a computer program/digital tool. Another option would be to use index cards to write the terms on them and then organize them on a flat surface and take a picture to submit when complete. This could be done with “sticky notes” on a wall too. There are lots of terms and you must consider how they will be organized together. Notice how, in the example above, the categories or ‘groupings’ that were not official scientific classifications (for example, simple invertebrates, worm-like invertebrates, complex invertebrates, joint-legged invertebrates, invertebrates, and vertebrates) do not have kingdom, phylum, or class in front of them. They are just classifications that scientists use to help them understand the living world. In your concept map, make…arrow_forwardHow is information from the field of embryology used as evidence for evolution.arrow_forward
- Serial endosymbiosis is the most supported theory on how the first eukaryotic cells evolved from prokaryotic cells. The figure depicts the evolution of eukaryotic cells which include links to prokaryotic cells from early in the history of life. Identify the cellular structures involved in the connection of eukaryotic and prokaryotic cells. Describe the characteristics of the cellular structures that supports the evolutionary connection. State a claim on how eukaryotic cells evolved. Using evolutionary evidence justify your claim. The cells modeled above are a result are descendants of an original cell.arrow_forwardwhich statement is false? 1)In the context of the evolution of senescence, the aphorism "live fast and die young" means that organisms with a more risky behavior will have a shorter life span. 2)Allopatric speciation is a type of speciation process that takes place in different geographic locations.arrow_forwardIdentify the benefits and costs of sexual recombination in the context of evolution.
