Animals that form part of the tree of life
Explanation:
The tree of life is a diagram used in evolutionary biology to organize life into categories and to classify different species. In this case, tuna, turtles, and chimpanzees and humans are species that can be grouped in the animal category, within the vertebrates group (chordate phylum), being it the most inclusive level at which all these species belong.
Answer: The correct answer is rRNA and protein.
Explanation:
Ribosome is a cell organelle present in the cytoplasm of all living cells. It is a site of protein synthesis in all type of cells. It is made up of two sub-units namely, small sub-unit and large sub-unit.
Both the sub-units are formed by rRNA (ribosomal RNA) and associated proteins. rRNA is ribozyme, that is, it is a ribonucleic acid with catalytic ability. The protein component helps in providing the structure to the ribosome.
