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
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.

Researchers have found that the more World Cup soccer a student watches the better they do on their exams. Students reported the amount of World Cup soccer they had watched in the two weeks leading up to their midterm exams. The more soccer watched, the better the student’s exam grades tended to be. Researchers are not yet sure why soccer viewing improves intelligence, but plan further research during the next World Cup qualifiers as well as research examining other sports. Which of the following BEST captures the most significant flaw in this research as it is written? What type of design is this? Using an exam score as a measure of intelligence is an example of?
Answer:there could be a placebo effect that accounts for results
Explanation:
There is not enough info about experiment nor is there a group that didn’t watch soccer
Following are the solution to the given question:
For question 1:
The study is correlational, but still makes a causal claim the correlation just reveals the direction and size of such an association between variables; correlation does not imply causation.For question 2:
This researcher establishes a link between two variables, namely football viewing, and scoring. This correlational research looks into correlations between variables without helping researchers control or manipulates any of them. It expresses the strength and/or direction of a link between two (or more) factors. This correlation's direction could be either positive or negative.For question 3:
Parsimony is demonstrated by using an exam score as a measure of intellect. It is defined as extreme frugality or the practice of spending money with great prudence. When you carefully consider every purchase and are wary about spending even tiny sums of money.Therefore, the answer is "Option 1, correlational, and parsimony".

Which of the following best explains the diffusion of plants and animals from their hearths of domestication?
A. Animals were domesticated before plants and diffused rapidly from their hearth of domestication through contagious diffusion because they were mobile and moved easily from place to place.
B. Domesticated plants spread through wind-borne dispersal of seeds from their original hearth, expanding slowly until a vast region was covered with new plants.
C. Both domesticated plants and animals spread across the globe through contagious diffusion in early years by farmers and traders, and later by relocation diffusion through European exploration and colonialism.
D. The diffusion of plants and animals was limited to areas close to each hearth of domestication because the newly developed plants and animals could not readily adapt to different soil types.
E. The diffusion of plants and animals was dependent on nomadic traders who traveled between agricultural villages because early farmers were sedentary and did not travel to other areas.
Answer: C. Both domesticated plants and animals spread across the globe through contagious diffusion in early years by farmers and traders, and later by relocation diffusion through European exploration and colonialism.
Explanation:
At first, domesticated plants and animals were spread via contagious diffusion which is what happens when people in a certain area or locale come into contact with another.
When the Europeans began to explore and colonise the rest of the world, they engaged in relocation diffusion by taking the plants and animals they knew to the new areas and then taking the plants and animals from the new areas back to Europe. This was how domesticated plants and animals spread across the world.
The best explanation for the diffusion of plants and animals from their hearths of domestication is option C.
Contagious diffusion in the early years was a way of spreading from one person to the other. These farmers and traders exchanged the domesticated plants between themselves.
The relocation diffusion happened as the European explorers moved from their original continents to other continents. They got to these new areas and they got hold of the new plants and the animals that existed in these areas.
They also traveled with theirs too.

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.
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 biodiversityAdaptation 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.

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