Darwin’s
research showed that finches beaks are different to fit their food source. It
also started the theories of evolution and natural selection. The
Grant’s research on the Galapagos Islands showed that evolution exists and can
happen over a course of two years. They proved Darwin’s theories are true. Since
all the plants and animals are native to the islands, they had to adapt to the
new food source and climate. Beaks, size, etc. are all changes made to these
organisms to be able to live on the islands.
The Galapagos Islands are located in Ecuador and
sit on the Pacific Ocean. <span>The Galapagos Islands were formed from 3 million
to 5 million years ago. Volcanic eruptions typically shield volcanoes formed
the islands. They are located over a “particularly hot mantel” that causes
volcanic activity. The outcome of many eruptions were islands because the left
overs were pushed to the surface. The Galapagos islands are pretty big reaching
an area of 3,093 miles. The temperatures range from 69 to 84 degrees creating a
typically warm climate. </span>
Darwin studied medicine at age 16, but became
fascinated specimens around the globe. He developed theories of natural
selection and evolution. While he was on the Galapagos islands, he studied
thirteen different species of finches.
He observed finches and different beak
structures. He observed their ability to consume foods such as nuts, bugs, and
fruit. He concluded all were related to their beaks. For example, long, slender
beaks are good to reach in the flowers of a cactus.
<span>Charles concluded that the finches beaks are
examples of adaptive radiation. To fit in the island, they had to adapt to the
conditions. This lead to Charles’ theory of natural selection. </span>
Charles came to the conclusion of evolution and
natural selection. Natural selection is the process where organisms adapt to their environment to survive and
produce more offspring. Evolution is where different kinds of living organisms
are thought to have developed. These theories have changed science forever and
leave today’s scientists marveling of his theories.

Reabsorption of filtered glucose from the lumen in the pct is largely by means of: secondary active cotransport.
Nephron is the functional unit of the kidney associated with removing waste products from the blood. It achieves the function by performing filtration which results in formation of urine. A nephron is divided into two parts namely renal corpuscle and renal tubule. Renal corpuscle is associated with filtration and renal tubule mainly performs reabsorption.
Renal tubules are further divided into Proximal Convoluted Tubule (PCT), loop of Henle, Distal Convoluted Tubule (DCT) and collecting duct. PCT and DCT are mainly linked with reabsorption and secretion respectively. Reabsorption in PCT occurs via cotransport. Here, glucose is reabsorbed along with sodium ions via SGLT2 cotransporter. Specifically, the reabsorption method is termed as sodium-coupled secondary active transport.

<span>In general, a species' realized niche will be smaller than its fundamental niche due to interactions with other organisms in the community.
Hope that helped you.
