Answer:
The elephant and the sheep exhibit higher sequence similarity because they are more closely phylogenetically related
Explanation:
The elephant and the sheep are mammals, while the crocodile is a reptile, being the mammals the most inclusive group among these three species and it appeared later in evolution. Mammals are organisms that have shared evolutionary features such as warm blood, they produce milk and have hair
Answer:
Immortal cell line
Explanation:
An immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular operation and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro
Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms. Immortalised cell lines have also found uses in biotechnology.
A frog is an amphibian so it survive both on land and water
