________________ (name the theoretical perspective) uses and believes in the scientific method to explore society.
Functionalism
Positivism
Conflict Theory
Symbolic Interactionism

Answers

Answer: Positivism

Explanation:

Positivism as a theoretical perspective uses logic to explain things. People who follow it believe that the world should be explored through the lenses of the scientific method because everything can be explained based on statistics and are only factual if proven by the scientific method.

They are therefore against the notion that things work due to metaphysical forces and also believe that knowledge cannot be acquired unless events confirming that knowledge have been experienced.

How can we calculate fracitons

Answers

Answer:

To find a common denominator, multiply each part of a fraction by the denominator of the other fraction. For example, to find a common denominator for 1/3 + 2/5, multiply the 1 and 3 by 5 and multiply the 2 and 5 by 3. You should get 5/15 + 6/15. Then you can calculate the fractions.

Two ecologists, Robert H. MacArthur and Edward Wilson, studied how organisms immigrate to islands and how their numbers change after colonization. They developed the island biogeography model to explain the composition and diversity of island species. The graph below shows the number of species versus the size of the Caribbean island:

Use the Species by Area graph to answer the following:
Describe the relationship between species number and island size observed in the data.
Describe two additional factors that affect species richness on islands.

Scientists have found that most species on the same continent are more closely related to each other than to organisms on other continents. They hypothesize that this phenomenon is due to the evolution that occurred after the continents split apart, or in the case of island biogeography, after islands formed off the coast of mainland regions.
Explain the role of adaptive evolution in island biodiversity.
Describe one process that leads to speciation of islands.
Explain how the biodiversity of an island affects its ecological tolerance to change.
Explain how specialist species are affected when generalist species migrate to an island.

Island ecosystems experience ecological succession in different stages of their development.
Describe the process of primary succession on an island.
Describe the process of secondary succession on an island.
Identify two scenarios that lead to secondary succession on an island. Explain how these scenarios can affect island biodiversity.

Answers

There is a directly proportional relationship between species number and island size. Two factors that may affect species richness on islands include food availability and the presence of predators.

Adaptive evolution and island biodiversity

Adaptation refers to the evolutionary process by which species fit specific environmental (island) conditions.

Island biodiversity is a consequence of the adaptive process by which organisms can adjust to specific island conditions.

Speciation refers to the emergence of reproductive barriers between individuals of the same population, which occurs in islands due to geographic separation.

With higher tolerance to change, will be higher the biodiversity (i.e., number of species) of an island.

Generalist species can negatively affect specialist species living on an island because they can also fit the same environmental conditions (and therefore compete for limited resources).

Primary succession refers to the process by which species first colonize a lifeless habitat, whereas the second succession on the island occurs by new processes of migration.

As Earth warms:
• Ice cover melts, exposing soil or water
• Albedo (Reflectivity of sunlight) decreases
• More energy is absorbed by Earth's surface
• Global temperature rises
• More ice melts

IS THIS A NEGATIVE OR POSITIVE FEEDBACK LOOP AND WHY?

Answers

it’s negative because eventually all of the ice will melt and many countries will be covered in water due to too much heat in the atmosphere

it is negative because as the ice has melted, dark ocean water is said to be released and this leads to a lot of changes in the surface.

Is there an albedo increase or decrease when ice melts?

Note that in global warming, there is a rise in feedback when there is reflective ice (that is, one has a higher albedo) when compared to land or water surfaces.

Conclusively, it is negative because as the ice has melted, dark ocean water is said to be released and this leads to a lot of changes in the surface and thus cause an albedo effect.

Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state. Which of the following would most likely increase the negative effects of nitrogen pollution?

Answers

Answer:

Loss of biodiversity in the wetlands.

Explanation:

Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.

Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.

Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.

The number of carbon atoms in 9.30x10^-3 moles of Na2CO3​

Answers

Answer: [tex]56\times 10^{20}\ \text{atoms}[/tex]

Explanation:

Given

No. of moles of [tex]Na_{2}CO_{3}[/tex] is [tex]9.30\times 10^{-3}[/tex]

So, for [tex]9.30\times 10^{-3}[/tex] moles of [tex]Na_{2}CO_{3}[/tex]

There are [tex]9.30\times 10^{-3}\times 6.022\times 10^{23}\ \text{molecules of}\ Na_{2}CO_{3}=56\times 10^{20}\ \text{molecules}[/tex]

1 molecule of  [tex]Na_{2}CO_{3}[/tex] contains 1 atom of carbon

i.e. there are [tex]56\times 10^{20}\ \text{atoms of C}[/tex]
