The correct answer is option C
The stage of evolution represented by the middle finger must be imbibed by the letter ‘M’ in its name which depicts the “mutation”. In mutation a new gene is added to produce variation in the frequency. The other fingers depict the following stage of evolution:
a) Pointer finger depict the evolution caused by the movement of an individual or species into or out of the area. This finger represents gene flow.
b) The small finger represents the shrinking of population and thus represents the change in gene flow due to any mishappening or epidemic or calamity. This finger represent the small population
c) The ring finger represents the evolution caused by mating/sexual intercourse. This finger represent non random mating
d) The thumb represents the natural selection through adaption.
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!
The cell would die. This is because mitochondria are essential for making energy that the cell can use, if the mitochondria stopped working this energy would not longer be available to the cell. If the cell does not have energy, it cannot perform vital functions like respiration.
Hello! The interaction between the two system is an inter-dependent relationship. An example of this is that the heart pumps arterial blood to the circulation. The deoxygenated or venous blood returns to the lung where blood is oxygenated. Then the blood flows into the heart chambers and the cycle continues on.
False you can only live for 70 days without eating protein.
