The correct answer that would best complete the given statement above would be the term ADAPTIVE RADIATION. African cichlids are a group of closely related fish species. There are at least 500 known species living in three small lakes. Over time, specialized teeth and body colorations have evolved for each species in response to mutations and competition for food and mates. This change over time is an example of ADAPTIVE RADIATION. Adaptive radiation by definition, is <span>the diversification of a group of organisms into forms filling different ecological niches.</span>
Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10 thousand years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems and as "the total of arrangements, activities, and inputs that people undertake in a certain land type. Land use is one of the most important drivers of global environmental change.
The study of one type of evidence of evolution is called embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases. Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart.
Answer: Option B) phosphate; hydroxyl; 3'
We identify nucleic acid strand orientation on the basis of important chemical functional groups. These are the phosphate group attached to the 5' carbon atom of the sugar portion of a nucleotide and the hydroxyl group attached to the 3'
carbon atom
Explanation:
For both RNA and DNA, chemical groups such as phosphate (PO3-) attaches to the 5' carbon of the pentose sugar (deoxyribose in DNA, ribose in RNA).
While hydroxyl group (OH) attaches to the 3' carbon atom of the pentose sugar.
Thus, a nucleic acid structure structure reveals a several repeating units of nucleotides where nitrogenous base links to a pentose sugar, who in turns is linked to phosphate group
Well, to answer your first question, Because there are places on Earth that are both biologically rich — and deeply threatened. For our own sake, we must work to protect them. and for your 2nd question, 3 characteristics of magnetic reversal are: field, bar magnet, and molten material. Hope this helps
