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

How is human cognition similar to the way a computer works?

The Human Brain Versus The Computer. Computers are said to work much like the human brain in that both systems access and configure information in stages. First, input is received, next the input is processed, then the information is stored to memory, it is then configured, and lastly output is created.
