The arms of humans in the flippers of dolphins have the same bone structure so they blank organisms the legs of kangaroo and the legs of jumping spiders allow both organisms to jump however spiders are invertebrates and kangaroos are vertebrates this difference makes their legs blank structures

The arms of humans in the flippers of dolphins have the same bone structure so they homologous organisms the legs of kangaroo and the legs of jumping spiders allow both organisms to jump however spiders are invertebrates and kangaroos are vertebrates this difference makes their legs analogous structures

Explanation:

Homologous organisms are organisms that have bodily elements that have the same basic structure and the same embryonic development, but have different functions, or not. This means that these organisms had the same ancestor in common at some point in their evolution. This can happen in organisms totally different from one another and an example of this can be seen in the arms of humans in the fins of dolphins that have the same bone structure, but different functions.

Analogous organs, however, are seen in different organisms that present bodily elements with the same or similar functions, but that do not have any type of ancestry in common. An example of this can be seen in the fact that the legs of the kangaroo and the legs of the jumping spiders allow both organisms to jump, but the spiders are invertebrates and kangaroos are vertebrates.

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
