Answer: The hammer, anvil and stirrup—also known as the malleus, incus, and ... To understand the role of these bones in hearing requires an understanding of levers. This is because the middle ear ossicles are arranged and interact with ... in an actual stirrup—is loosely attached to the oval window of the cochlea.
Explanation:
5. Mitosis - cell division that produces two daughter cells that are identical to the original parent cell
2. Growth - the increase in size of cell or number of cells in an organism
6. Reproduction- the process by which cells produce new cells like themselves, or by which an organism produces an offspring
4. Metabolism all of the chemical processes in an organism that provide for the maintenance and functioning of the organism
3. Homeostasis - the maintenance of a relatively constant state in the internal environment of an organism
1. Adaptability - the change by a living organism in response to a change in the environment
Answer:
the biceps and triceps muscles work together to allow you to bend and straighten your elbow. When you want to bend your elbow, your biceps muscle contracts, and, at the same time, the triceps muscle relaxes.
Explanation:
Answer: Analogous structures are those that have a similar function but whose origin is different. Homologous structures have the same function and also start from the same origin.
Explanation:
Convergence is the evolutionary phenomenon by which different organisms that are evolutionarily distant tend, under equivalent environmental pressures, to develop analogous characteristics.
Analogous structures are those that have a different evolutionary origin, but fulfil very similar functions. For example, the wings of a bird, the wings of a bat and the wings of an insect all are for the same thing (flight) but their phylogenetic origin is not the same. This means, they fulfill <u>similar functions by similar means, without having the same evolutionary origin.</u>
The development of homologous structures occurs through divergent evolution, where two related species change a common ancestral structure during their evolution in order to survive by performing different functions.
Then, if they have the same evolutionary origin, they are homologous. <u>So, if two structures have the same function by similar means and also start from the same origin, they are homologous structures.
</u> For example, the extremities of vertebrates, similar skeletal structure, but for different uses.
