A musk ox and the Alstroemeria flower have physical structures and organs that have similar functions. Provide two examples of s
gladu [14]

Answer:

Mammals

Birds

Explanation:

The Organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.

Organs are the structures that made up of two or more tissues organized to carry out a particular function.

An organ or bone that appears in different animals with same function is called homologous structure.

Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.

Different animals have bones that appear very similar in form or function and seem to be related.

Examples

The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar sharing common traits.

The forelimbs of all mammals have the same basic bone structure.The structures are similar because they evolved to do the same job.  For example, the wings of bats and birds.

Compare and contrast bioarchaeology and forensic anthropology. What are their similarities and differences? g
Rina8888 [55]

Answer:

Bioarchaeology is a discipline that studies human skeletal remains in an archaeological investigation; while forensic anthropology refers to the study of human skeletal remains in a criminal case  

Explanation:

Bioarchaeology is a discipline centered on the study of skeletal remains in order to obtain useful information about past societies/civilizations such as, for example, health conditions. On the other hand, forensic anthropology investigates human skeletal remains within a legal and/or criminal investigation. This information may result useful to identify a dead person, find the cause of death, and estimate time since death.

Similarities:

-Both disciplines have a strong biology background (especially in zoology)

-Both disciplines are focused on skeletal analysis

Differences:

-Bioarchaeology is associated with the anthropological study of human societies, while forensic anthropology associated with legal investigations

Can spiders smell???????????
Naya [18.7K]

Answer:

Yes

Explanation:

Spiders, in fact, do taste, and also smell, through special sensory organs on their legs, as well as on their pedipalps. And they hear – or, more specifically, they sense vibrations – through hairs and tiny slits distributed over much of their body.
