Charles Darwin studied the the beak structure of finches native to the Galapogos Islands. The study of these finches enabled Darwin to study and publish his theory of evolution by natural selection. Darwin realized the importance of the finches after leaving the islands while he was studying specimens he brought back with him. The trait he noticed was the differences in the size and shape of the finches beaks. He theorised that new species will arise when some factor causes a population to be divided.

Explain three ways in which red blood cells are adapted to their function​
Salsk061 [2.6K]

Answer:

Red blood cells are adapted to their function by:

1) They contain haemoglobin - a red protein that combines with oxygen. they have no nucleus so they can contain more haemoglobin.

2) They are small and flexible so that they can fit through narrow blood vessels.

3) They have a biconcave shape (flattened disc shape) to maximise their surface area for oxygen absorption.

Hope this helps! :D

otez555 [7]

Answer:
