Use the drop-down menus to decide if an example of similar traits is likely a homologous structure or an analogous structure.
snow_tiger [21]

Answer:

- Bird wings and dragonfly wings are both used for flight: Analogous structure

- Clams and snails both have similar muscle structure even though the muscles do different jobs: Homologous structure  

- Human and giraffe necks both have 7 vertebrae because we are related: Homologous structure  

- The flaps of a Venus flytrap have a similar makeup to oak leaves: Homologous structure  

Explanation:

Analogous structures are similar structures that have the same or similar functions in unrelated organisms. Analogous structures aren't the result of evolutionary relationships among organisms (i.e., they were not inherited from a common ancestor). On the other hand, homologous structures are structures inherited from a common ancestor. Homologous structures may or may not have an identical function, but they are the result of evolutionary relationships among organisms and, therefore, they are genetically related.

Apart from this reduction in chromosome number, meiosis differs from mitosis in yet another way. Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells.

4. Which of the five classes of arthropods is the most diverse? Explain.
qaws [65]
<span>Insecta or Hexapoda (insects) is the most diverse class. There are about 900,000 known insect species, three times as many as all other animal species together, and thousands of new ones are described each year. They are commonly grouped in 27 to 32 orders, depending upon the classification used. The largest order is that of the beetles (Coleoptera). Next, in order of size, are the moths and butterflies (Lepidoptera); the wasps , ants , and bees (Hymenoptera); and the flies and mosquitoes (Diptera). Other major orders are the true bugs (Hemiptera); the cicadas , aphids , and scale insects (Homoptera); the grasshoppers and crickets (Orthoptera); the cockroaches (Blattodea); and the mantids (Mantodea). 

I hope that this is the answer that you were looking for and it has helped you.
