Answer;

It is impossible to tell from the data provided.


Explanation;

Different animals can be categorized as either protostomes and deuterostomes based on certain features of their embryonic developments.

For those categorized as protostome; the features include; mouth from blastopore, spiral,determinate cleavage, and coelom from solid masses of mesoderm

Those categorized as deuterostome have features such as coelom from folds of archenteron, radial, indeterminate cleavage, and anus from blastopore.

Which of these species would be most in danger of becoming extinct if one of their food sources became unavailable?
Advocard [28]

Answer:

Due to their being no options (possibly just an incomplete question), I will just give an answer. So for panda bears, if their food sources became unavailable, they would most likely be in danger of becoming extinct.

But one thing is, pandas do have the ability to survive with bamboo.

But since bamboo comprises 99 percent of their food, although they also consume other plants and even meat, I highly doubt they could (whose make the remaining 1 percent ).

Because the gene T1R1 mutated some 4 million years ago, causing them to lose the ability to taste umami, giant pandas have come to rely significantly on bamboo (which is what makes meat tasty for omnivores and carnivores). The availability of bamboo trunks at the time coincided with their purported food source becoming increasingly limited, thus pandas became used to them and began to rely significantly on them, as they do now.

Thank you,

Eddie

Endoskeleton is not a characteristic of Arthropods that has attributed to their diversity and success. Endoskeleton is defined as inner characteristics of the skeletal feature of an organisms such as bears, humans, fish and etc.

Exoskeleton on the other hand is the trait by which arthropods posses. It is skeletal feature that is described outside or is extrinsic, this is evident as crabs have their skeletons outside of their body.
