Answer:
the brown bear (<em>ursus arctos</em>) also known as "brown bear" has at least 16 subspecies recognized by Wilson & Reader (2005) of which at least 5 are considered extinct. These plantigrades are currently considered in danger of extinction and from the phylogenetic point of view, they have been attributed to have a polyphylogenetic origin or polyphyletic lineage, which means the sequence of arrangements of species from ancestors to the descendant through evolution.
Explanation:
Genomic analysis using different statistical methods showed that the genetic flow is not limited to pairs of closely related species. There is a high flow of ancestral genes between the Asian black bear and the ancestors of the polar bear, the brown bear and the American black bear, which explains the difficulties encountered in reconstructing the phylogeny of the bears and that, up to now, lead to the conclusion of its polyphyletic linage.
Answer:
social qualities such as fairness, freedom, security and tolerance above economic concerns. Having well-paid work and the absence of poverty are important chiefly because they help people to live fuller lives
A Good Society is what we strive for and we aim to build it around core values: Equality, Democracy and Sustainability. Rather than being a specific vision, or end point, the Good Society is a framework that enables us to evaluate political ideas and actions against our core values.
Rudimentary Democratic Consent.
Universal Access to Human Essentials.
Access to Other Desirable Items.
Freedom and Liberty.
Equity and Fairness.
Environmental Sustainability.
Balance.
The economic term is the opportunity cost.
The concept of opportunity cost is a relatively inexpensive and relative measure that involves people's preferences, so it varies from person to person. It is a question of comparing what is left over when making a decision.
In Katie's case, the opportunity cost of the money she saves to buy a car is what she fails to do with that money. For example, she stops investing in stocks, fails to make a trip, etc.
All decisions involve an opportunity cost. Taking another example, the opportunity cost of studying for the test at the end of the week is measured by the loss of leisure you would have. However, the decision to study for the test is chosen because it is more valuable.
Answer:
Each island was founded by a colonizer, perhaps from a mainland, and divided up ecological niche space as they diversified into the four species present.
Explanation:
Phylogenetic analysis is the study of determining the evolutionary relationships of species. Phylogenetic is important because it makes us understand how different species evolves.
In the given context, four species of the lizards in the four Caribbean Island are descended from the four separate common ancestor of four different species.
Thus it can be concluded that each of the four Caribbean Island was founded by a lizard species colonized to that area or might have come from the main land and played an important role in the ecological niche as they varied and expand into present four species.
Hence the answer is ---
Each island was founded by a colonizer, perhaps from a mainland, and divided up ecological niche space as they diversified into the four species present.
Brazil is a country that has very interesting culture which is the result of the mixing of several different cultures. What is now Brazil has been colonized by the Portuguese people. As they did, they started to settle in, but it was not just Portuguese that settled, there was also lot of Italians as well. As they were the ones that controlled this area, they set up the basis for the modern day culture of Brazil. But that is not all. The colonists encountered lot of native tribes, and over time the natives and the Europeans started to mix. Also, the colonists brought lot of African slaves too, and once the slavery ended, they too started to mix with the Europeans and natives. Each of the three sides contributed with their own cultures, gradually creating one melt resulting in the modern day Brazilian culture. Some of the well known traits of the Brazilian culture is the dancing, carnivals, masquerades, practicing of old traditions, being passionate Catholics, having excellent football skills based on the ginga etc. The ethnic composition too has been influenced in the same manner through the mixing of the people from three different races, making the modern day average Brazil having genes from three sides of the world.
