Hi
It is true that on the Galapagos islands Darwin observed tortoises with a dome and saddle shaped shells, you can see both in attached image.
Darwin observed that Galapagos Tortoises had the shells with different shapes depending on the Island they live, For example: The tortoises with saddle shaped shells were able to reach up to eat leaves of plants while the tortoises with dome shaped shells would not reach up and they would eat food from on ground sources. This made him think that the differences in tortoise shell is also a strong evidence that indicates that how tortoises have adapted themselves to better get their food as per the available resources and how they have evolved from same ancestral specie into two different species. This point also helped him in proposing the theory of evolution by natural selection.
Hope it helps!
For an animal to be extinct none more of that specific species must exist on Earth. This makes it impossible for that species to come back to life.
Answer:
(a)-Kinesthetic
Explanation:
- The <em>Vestibular sense </em>is responsible for our sense of spatial orientation or balance.
- The Auditory sense is responsible for the perception of sounds.
- The Umami Olfactory sense is responsible for our sense of smell and taste.
So the answer is (a), kinesthesic. It is thanks to the kinesthetic sense that we can go up stairs easily without stopping to see and carefully control the movement of each of our legs.
the answer is B: It is made up of amino acids.
