Base your answers the questions below on the information provided and your knowledge of biology. Ocean-dwelling (marine) iguanas
and land iguanas inhabit the Galapagos Islands. Some scientists believe that both types of iguanas diverged from a common ancestor. Marine iguanas eat algae. Land iguanas feed on cacti. Algae are more abundant in the ocean than cacti are on the islands. Both species lay their eggs in the sand. Rats, cats, and goats have been introduced to the islands by humans. Rats feed on iguana eggs, cats eat baby iguanas, and goats eat cacti. • Which population of iguanas, marine or land, would you expect to be larger? Support your answer. • Identify one technique that can be used to support the conclusion that these two species of iguana developed from a common ancestor.
Evolutionary adaptation can be defined as the process of adjustment of organisms to particular environmental conditions in order to increase their chances of survival. Moreover, natural selection is the main mechanism by which organisms adapt to their environments. Adaptive radiation can be defined as the evolution of a specific taxonomic group (for example, a species o genus) into specialized organisms which are adapted to survive under particular environmental conditions. Adaptive radiation can lead to speciation by which populations evolve (change) to become distinct species.
New York is bordered by Canada and Lake Ontario in the north; Pennsylvania, New Jersey, and the Atlantic Ocean in the south; Lake Erie in the west; and Connecticut, Massachusetts, and Vermont in the east. The St. Lawrence-Champlain Lowland runs along the edge of the Adirondack Mountains and the Canadian border.
Abnormal BRCA1 and BRCA2 genes are found in 5% to 10% of all breast cancer cases in the United States. A study found that women with an abnormal BRCA1 gene had a worse prognosis than women with an abnormal BRCA2 gene 5 years after diagnosis.
The lowest level that exhibits the characteristics of life are cells.
A Cell is the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.
The greatest biodiversity on earth is found in the TROPICAL RAIN FOREST BIOME. The tropical rain forest has constant temperature and high rainfall, because of this the biome contain a diversity of ecological niches which ranges from the forest floor to the canopy. High level of reproduction is also possible as a result of high rainfall that is experienced in the biome.<span />
The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
