Which advance in biology resulted from developments in cell technology?

Mariulka [41]

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 bird is observed to nest along the coastline. It then spends hours out in the open ocean feeding on fish. What is this behavio

3241004551 [841]

Answer:

Nesting & Foraging behavior

Explanation:

Seabirds are generally tertiary consumers and / or marine predators that, in marine foodwebs, occupy the upper trophic level. They are very well adapted to all marine ecosystems and feed on a variety of prey: from micro-crustaceans to fish and cephalopods.

Generally, seabirds are observed performing a nesting behavior, by laying eggs near the shore, and then are found exhibiting foraging behavior -searching and foraging for prey- in both the coastline and pelagic zone, also known as the open sea.

Seabirds exhibit different foraging behaviors, for example, the surface feeding behavior which involves flying along the surface with their beak in the water. Gulls, albatrosses and petrels are examples of surface feeders.

On the other hand, plunge diving involves preying on fast marine organisms by diving into the water during their flight. Pelicans are example of seabirds who engage in this behavior.
