A human's internal organs are protected mainly by the
a. hydrostatic skeleton.
b. axial skeleton.
c. exoskeleton.
d. appendicular skeleton.

Accepted Answer

Hi everyone. Let's look at our next question. It says Which of the following do not have an endo skeleton? Let's recall from our content videos when an endo skeleton is? That's an internal skeleton composed of mineralized tissue like bone and its present invertebrates. So let's look at our answer choices here. And we've got choice eight arthropods. Well there we go. There's our correct answer. Arthropods are not vertebrates. They have an exoskeleton external skeleton and it's made of chitin that they have to shed and regrow when they outgrow it. Let's just look at our other answer choices and we see choice be mammals, choice, sea birds and choice D reptiles. These are all vertebrates with a bony exoskeleton, endo skeleton. Excuse me. Um So none of these are our correct answer. So again, which the following do not have an endo skeleton? And that would be choice a arthur Potts. See you in the next video.
