Temporal bones are the bones of the skull which are most
associate with hearing and balance.
Skull is made up of many types of bones, temporal bones are
one of them. These bones are present at the base and sides of the skull. Temporal
bones consist of many parts, as these bones are present at the side of the head
so that’s why they are associated with hearing. They are also known as house the
structure of ear.
Answer:
Circulating air is diverted due to the Earth's rotation. Instead of flowing in a straight line, air in the Northern Hemisphere deflects to the right, whereas in the Southern Hemisphere it deflects to the left, resulting in curved trajectories. The Coriolis effect is the name for this deflection.
Explanation:
• Homologous structures: Both Ostriches have wings similar in form to those of their ancestors, but that do not allow the birds to fly.
Homologous structures are those that have structural similarities but are different in function. For example, if we look at the anatomical structure of a bird’s wing, it is very similar in structure with a human arm. However, over the course of time they have evolved to perform different functions.
• Vestigial structures: The inner ear bones of mammals have evolved from bones that form the jaws of reptiles.
Vestigiality refers to the process in which some structure lose their function over the course of evolution in some specie but they are functionally normal in other species. Such a structure is the inner ear bones of mammals which donot perform an important function in mammals but do perform in reptiles.
• DNA sequence data: Both Genes involved in RNA replication are conserved among bacteria and animals, suggesting a common evolutionary origin.
The sequencing of genetic data is an excellent method of finding the evolutionary histories and relatedness of different organisms. This field of sciences is called phylogenetics and the mentioned example is the result of phylogenetics.
• Analogous structures: The jointed legs of insects and vertebrates arose independently, indicating a different evolutionary origin.
Analogous structures are those that have similar function but they look very different in structure or anatomy. This is because they have been evolved from different ancestors and perform different functions. One example of these structures is mentioned, The jointed legs of insects and vertebrates that look different bur perform same function.
