Which of the following is not a true statement comparing exoskeletons and endoskeletons?
nordsb [41]

Answer:

Exoskeletons provide less mechanical leverage.

Explanation:

There are two types of skeleton in living beings: the endoskeleton (which vertebrates possess, is lined with epithelial tissue and has bones and cartilage) and the exoskeleton, a skeletal structure that is located outside the body of the living being. , is an external skeleton. They are common in invertebrate animals, which have no internal bone structure.

The exoskeleton is a tough but flexible outer layer, not formed by bones, unlike the vertebrate endoskeleton. Its function is mechanical, chemical and biological protection, avoid excessive water loss, muscle support and serves as a connecting point for legs, wings and other appendages. However, this type of skeleton provides less mechanical leverage.

On the other hand, the endoskeleton is the name given to the internal skeleton, which is inside the body. This body structure is mainly seen in vertebrate animals and has the function of supporting and moving the body, as well as protecting some internal organs. Unlike exoskeleton, the endoskeleton provides more mechanical leverage.

How are the tortoises that Darwin studied on the Galapagos similar to the anoles that Losos studied in the Caribbean
madam [21]

Answer:

Some tortoises, including Lonesome George, have shells that rise in front, like a saddle. This adaptation makes it easier for them to lift their heads high to eat tree cactus and to resolve disputes over limited food resources, which they do through raising their heads as high as possible during social interactions.
