Squid tentacles have hundreds of tiny suckers, and each sucker has its own ring of razor-sharp "teeth"
that help the squid catch its prey.
Because these sucker ring teeth (SRT) are made entirely of proteins, they are different from
most other natural polymers and hard tissues such as bones, which need minerals or other substances
to function properly.
오늘도 질문이 있습니다 T.T
영어는 너무 재미있지만 너무 어렵네요
본문에서 which가 가리키는 것이 these sucker ring teeth 인지
most other natural polymers and hard tissues 인지 아니면 bones 인지 헷깔립니다
늘 감사드립니다 :)
