Answer:
Darwin's research on Galapagos Island put forward his theory of natural selection.
Explanation:
1. Charles Darwin studied the similarities of the finches between the various islands of Galapagos. His study noted that the finches were similar from island to island making him to wonder about the origin of this species as these perfectly adapted to their environment. His compilation of observation about the finches, the fastest evolving vertebrates, described its behavior and appearances which changed according to the changing environment., thus making them to adapt quickly. These were further converted for his book 'The Origin of Species' that changed the concept of evolution.
2. Grants research on Galapagos Islands were conducted by Peter Raymond Grant and Barbara Rosemary Grant, both evolutionary biologists. Their work focussed on the Darwin's finches through processing of collecting blood samples and tagging them. They were able to indicate that changes within the species is evident within a single lifetime. Their study indicted that changes in populations takes place quickly and need not wait for long time as indicated in Darwin's theory.
3. The Galapagos Island is a ground to more species that have risen due to adaptation. Due to its remote location, it was possible for the scientists to conduct study about natural selection on biodiversity. THere are 18 species that have evolved from Darwin's finches. The diversification observed in the finches were the shape and size of beaks.
The Darwin's finches developed over time with strong crushing and probing beaks adapted to catch insects or crack nuts. Even some have sharp long beaks to drink blood.
Another species observed is the marine Iguana with adapted short blunt stout, and long tail to swim deep into sea.
The flightless cormorant found in this island, were adapted to survive as there was no necessity to fly. Instead their dense bodies, small feet, and powerful legs makes them to be good divers to hunt fish, eels, and small octopus.
It is because when alleles show a co-dominant relationship , neither allele is dominant and both are expressed in the phenotype of the heterozygote. The human ABO blood groups provide a good example of codominace. The ABO system is due to a gene that codes for molecules on the surface of red blood cells
Answer:
1. They can have constant trained medicals around them, which is good because they could have emergencies.
2. They won’t be alone in there houses, but instead have people and life surrounding them.
3. They’ll have people taking care and looking out for them, other than family.
4. They’ll be comfortable, more happy, and more likely to live a happy end to their lives.

Explanation:
In order to test for starch and distinguish the beaker containing a mixture of startch and water, a small quantity of the solutions in each beaker should be taken and and drops of iodine added. The solution that gives off a <u>blue/black</u> color from the yellow/brown color of the iodine would be the starch water solution.
<em>Generally, starch turns iodine solution to blue/black from the usual yellow/brown color of the substance.</em>
