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.
A pyramid of energy can never be inverted because energy decreases by tenfold each level. This can't be reversed because energy can't just increase by tenfold. It has to come from somewhere.

Answer:
Abstract American photographer Catherine Opie combines portraiture and documentary photography in her photographic series titled Domestic. At the center of this series lies the idea of community and the question of how community is constructed, a theme which unites Opie’s seemingly disparate bodies of work.
Explanation:
Answer:option C= mRNA
Explanation:
MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.
The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.
mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.
