If enough experimental data supports a hypothesis, then it:
O A. Is proven 100% true.
O
B. Is falsified.
OC. Is accepted as true until prolan false.
OD. Becomes an Observational Law

Answers

Answer: C) Is accepted as true until proven false

==========================================================

Explanation:

We cannot prove the hypothesis to be 100% true because there might be data out there that we haven't accounted for, or some scenario that we haven't thought of yet. There's always going to be room for uncertainty and doubt. Keep in mind that such doubt does not necessarily mean that the theory is automatically false.

So all of this rules out choice A.

Choice B is ruled out as well because data supporting a hypothesis doesn't falsify the hypothesis. The term "falsify" means "to prove false" as you'd expect.

Choice C is the answer because the data seems to support the hypothesis and again we leave room for error. It's quite possible that in some unspecified date in the future, there are better methods of measurement to get a better sense of what's going on.

Choice D is ruled out because a law refers to something like the law of gravity. It's something you observe but it doesn't explain why something works. It doesn't provide the underlying mechanics of what's going on. We simply just report what we see which is exactly what an observation is.

Complete the sequence of numbers in this set. Explain the pattern.
7.5, 6.25, 5, ___, ___

Answers

The complete sequence will be:

7.5, 6.25, 5, 3.75, 2.50

This is an arithmetic sequence. The formula to find the nth term of an arithmetic sequence is:

= a + (n - 1)d

where,

a = first term = 7.5

n = number of terms

d = common difference = 6.25 - 7.5 = -1.25

Therefore, 4th term will be:

= a + (n - 1)d

where, n = 4

= a + (4 - 1)d

= a + 3d

= 7.5 + 3(-1.25)

= 7.5 - 3.75

4th term = 3.75

5th term will be:

= a + (n - 1)d

where, n = 5

= a + (5 - 1)d

= a + 4d

= 7.5 + 4(-1.25)

= 7.5 - 5.0

5th term = 2.5

In conclusion, the 4th and 5th terms are 3.75 and 2.5.

As a river flows downhill carrying sediment, what happens when the river widens and slows down?
O A. The largest particles are deposited.
OB. The smallest particles are deposited.
C. Larger particles are picked up by the current.
D. Smaller particles are picked up by the current.

Answers

Answer: A

Explanation:

As a river flows downhill carrying sediment, the largest particles are deposited. The correct option is A.

The river loses the energy needed to move and carry heavier particles as its velocity drops. These larger particles start to settle when the water's force is no longer sufficient to hold them suspended.

Deposition or sedimentation are terms for this process. Due to their greater bulk and lack of buoyancy, the larger particles—such as boulders and pebbles—tend to settle first.

Smaller particles, such silt and clay, on the other hand, can float in the water for a longer time due to their higher buoyancy and lower mass.

Thus, the correct option is A.

Please select the best answer from the choices provided
True
FALSE

Answers

Text books are not a good source for finding ideas about what to study because the teachers make up the test questions. FALSE.

While it is true that textbooks may not provide the most innovative or cutting-edge ideas, it is inaccurate to claim that they are not a good source for finding ideas about what to study simply because teachers make up the test questions.

Textbooks play a crucial role in education and are designed to provide foundational knowledge and concepts within a particular subject area.

Textbooks are typically written by experts in the field who have conducted extensive research and have in-depth knowledge of the subject matter.

They go through a rigorous editorial process to ensure accuracy and credibility.

Textbooks consolidate information from various scholarly sources, synthesizing complex concepts into a comprehensive and accessible format.

They often include references to primary sources, which can be valuable for further exploration.

Furthermore, textbooks are commonly used as a guide by educators to structure their lessons and assessments.

While teachers may create test questions based on the content of the textbook, this does not invalidate the usefulness of the textbook itself.

In fact, test questions derived from textbooks serve as a means for students to demonstrate their understanding of the material and apply their knowledge to real-world scenarios.

It is important to note that textbooks should not be the sole source of information for studying.

Supplementing textbook material with additional resources, such as scholarly articles, research papers, and online sources, can provide a more comprehensive understanding of a subject and expose learners to diverse perspectives.

The concepts of natural selection and evolution are central to how most biologists
understand and interpret the world, and yet the theory of evolution is contrary to the
beliefs of many religious groups. Why do you think this theory is so important to science
and so strongly opposed by others? What evidence would be required to convince
opponents of evolution?

Answers

Answer:

For many people of different religious beliefs, the theory of evolution does not pose a conflict. However, Christian fundamentalists, in particular, may portray evolution and religion as in opposition to each other. Some people think that, to accept the key tenets of evolutionary thought is to deny their religious beliefs, and this prospect can generate considerable conflict. This is not helped by some proponents of evolution, who make derogatory statements about religious beliefs and promote evolution as explaining all there is to know about life. It is important to understand that western science developed within the Church and Philosophers traditionally explained the wonders of natural life through a creator. However, our knowledge and understanding of the natural world, developed through the application of the scientific method, has provided us with a modern and testable explanation for the history and relationships of living things.

This writing team takes the position that there is no conflict between Religion and Evolution because they are two incompatible areas that have nothing to do with each other. We do, however, understand that this is not necessarily the opinion of all. We have, for that reason, prepared the following section to spark critical discussion and reflection on some of the issues.

Darwin and Evolution

Why were Darwin's findings so controversial, and why do they still pose a challenge to some people's religious beliefs.

Specialists' panel

We have documented a number of previously published statements from specialists, stating why the acceptance of evolution poses no threat to their faith, or to them teaching evolution at school.

Roundtable discussion

For the roundtable discussion we have asked scientists a set of questions to which they have replied. These could be used as a starting point for discussion and critical thought.

Darwin and Evolution

Darwin's book, "The Origin of Species" belongs to the category of scientific work that is much discussed but is often not actually read. His findings are amongst the most significant and important that have ever been produced by scientists.

Natural selection simply means the mechanism of evolution. Through this process, the organisms that are adapted to a particular environment will be able to survive.

Natural selection is vital to how organisms are able to adapt and change over time. Natural selection is a process that drives evolution. It also leads to the diversity of life.

The theory of evolution states that all species are related and then change gradually over time. This is contrary to religious beliefs that believe that everyone is made from the image of a superior being and that we didn't evolve.

What does it mean to say that contemporary psychology is part of a "cognitive revolution"?

Answers

Contemporary psychology is part of cognitive revolution because cognitive psychology adopts a scientific approach to the study of human behavior.

Psychology is defined as the the scientific study of the human mind and its functions, especially those affecting behavior in a given context according to Oxford dictionary.

Contemporary philosophy adopts a scientific approach in studying human behavior rather than a speculative approach.

The whole idea of "cognitive revolution" is the scientific study of the diverse ways of information perception, processing and storage. It is a more empirical approach towards the study of the cognitive roots of psychological disorders.

This movement started around the 1960s. Modern psychology, since this time have moved from behaviorism back to the study of cognitive processes.

Therefore, contemporary psychology is part of the "cognitive revolution".

Marine life, for example, is influenced by tidal patterns. Animals tend to be active or inactive depending on the position of the sun or moon. Numerous creatures, humans included, are largely diurnal that is, they like to come out during the hours of sunlight. Nocturnal animals, such as bats and possums, prefer to forage by night. A third group are known as crepuscular: they thrive in the low-light of dawn and dusk and remain inactive at other hours.When it comes to humans, chronobiologists are interested in what is known as the circadian rhythm. This is the complete cycle our bodies are naturally geared to undergo within the passage of a twenty-four hour day. Aside from sleeping at night and waking during the day, each cycle involves many other factors such as changes in blood pressure and body temperature. Not everyone has an identical circadian rhythm. Night people, for example, often describe how they find it very hard to operate during the morning, but become alert and focused by evening. This is a benign variation within circadian rhythms known as a chronotype.Scientists have limited abilities to create durable modifications of chronobiological demands. Recent therapeutic developments for humans such as artificial light machines and melatonin administration can reset our circadian rhythms, for example, but our bodies can tell the difference and health suffers when we breach these natural rhythms for extended periods of time. Plants appear no more malleable in this respect; studies demonstrate that vegetables grown in season and ripened on the tree are far higher in essential nutrients than those grown in greenhouses and ripened by laser.Knowledge of chronobiological patterns can have many pragmatic implications for our day-to-day lives. While contemporary living can sometimes appear to subjugate biology after all, who needs circadian rhythms when we have caffeine pills, energy drinks, shift work and cities that never sleep? keeping in synch with our body clock is important. The average urban resident, for example, rouses at the eye-blearing time of 6.04 a.m., which researchers believe to be far too early. One study found that even rising at 7.00 a.m. has deleterious effects on health unless exercise is performed for 30 minutes afterward.
