Answer 11

Acupuncture is an alternative medicine that uses wire-thin needles inserted by a trained practitioner into specific points in the body. This ancient form of pain relief and stimulation is said to benefit patients by blocking channels which practitioners claim allow pain to travel within the body. This practice became more widely recognized and used after a New York Times reporter wrote in 1971 of a positive experience with it after surgery.

Those who doubt the effectiveness of this treatment for pain attribute the pain relief to a placebo effect: if a patient believes something will reduce their pain, they will experience some relief. The National Institutes of Health says that acupuncture relieves pain and reduces nausea and vomiting, although it is unclear how it works. The few adverse effects reported are due to improperly sterilized needles or improper delivery, making this still a fairly low risk option. For anyone considering acupuncture, they should first research its effectiveness for their specific condition.

Answer 22

ok lets skip this one

Answer 23

wo animals that can be found at the Grand Canyon include the Abert’s and Kaibab squirrels. The Abert’s squirrel is found at the south rim of the canyon and in a few surrounding states. The Kaibab squirrel, however, can only be found at the canyon’s north rim, mainly on the Kaibab Plateau. The Kaibab squirrel is not found anywhere else in the world. Scientists believe that the squirrels are actually closely related and have developed separately as a result of geographic isolation. It is possible that the squirrels were separated by plateau erosion that separated the forests and isolated the Kaibab population. Some scientists are studying if the squirrels are now two separate species or if the Kaibab squirrel is simply a subspecies of the Abert’s squirrel. Separate species are unable to reproduce with each other. Which evidence would be used to support the claim that the squirrels are two separate species?
The Abert’s squirrel is found at the south rim of the canyon, but the Kaibab squirrel is found at the north rim of the canyon.
Geologists prove that plateau erosion is the main cause of forest separation in the region.
Scientists observe that Abert’s squirrels are slightly larger and have bushier tails than Kaibab squirrels do.
When placed together in pairs for study, no pair of Abert’s squirrel and Kaibab squirrel result in offspring.

Answer 24

i got this one i guess it's the last one we can skip it sorry

Answer 25

Is this like part of your lesson or something?

Answer 26

I think the answer is the last one that seems to be the most logical

Answer 27

s this a good scientific question?

“Is the lifespan of snowshoe hares, which are white in the winter and brown in the summer, affected by levels of winter snowfall?”
Yes, because the question is specific.
No, because the question cannot be tested in a laboratory.
Yes, because the question has already been answered.
No, because the question does not lead to a hypothesis.

Answer 28

The answer is A.

Answer 29

Answer 30

According to a recent encyclopedia entry about dog breeds, Labrador retrievers come in two specific breeds: English and American. The article cites six studies from several scientific journals about dog breeding showing that males of both breeds usually average 29-41 kg (65-90 lb) in weight, and females usually average 25-32 kg (55-70 lb) in weight. Anna’s female Labrador retriever weighs 38 kg (83 lb).

What does Anna’s dog’s weight indicate about the reliability of this source?
This is still a reliable source because it clearly cites scientific research.
This is still a reliable source because it is a printed book, not the Internet.
This is no longer a reliable source because Anna disproved the studies.
This is no longer a reliable source because Anna’s dog’s weight is in the range for males.

Question about a moral issue cannot be answered with scientific methods.

Answer 51

oted scientist Dr. Elsa Birde described the effect of adding a mixture of dried apples and raisins to the previous feed of sunflower seeds, millet, thistle seed, and cracked corn in bird feeders in her yard. Over three years, Dr. Birde observed that the new mixture increased the number of songbirds at her feeders, especially during the months of April and May. As she has done for several years, Dr. Birde recorded, at the same time each day, the number of birds at each of her four feeders. She noted that the third year using the mixture coincided with the largest increase. There was a twenty-five percent increase in the number of songbirds over times when this mixture was not used. Dr. Birde also noted that in the third year she used a specific ratio of the ingredients, carefully measuring, which she had not done in previous years. The third year also had a warmer than normal spring, and a construction project began in a neighborhood near Dr. Birde’s. Dr. Birde is now going to produce this formula for sale and advertise to customers that they may see the same twenty-five percent increase in songbirds at their feeders.

Answer 53

Which scientific claim can be made?
Songbird numbers will increase due to the effects of climate change increasing global temperatures.
Songbirds appear more often in April and May.
A combined ratio is the main reason songbird numbers increased.
A study by Dr. Birde showed that the number of songbirds in her yard increased due to a modified food source.

Answer 54

i know the first one is not right so we have 3 left

It is the last one
I agree with wassup 143

Answer 62

wow where did it go

Answer 63

Cranberries and grapes may have therapeutic value. A cranberry company obtained the patent for a process to extract the oil from cranberry seeds. According to the patent, this oil can be used to treat breast cancer or to reduce its incidence. The oil can be used in drinks and foods. A grape juice company claims to have evidence that certain grapes have health benefits ranging from improving cardiovascular health to improving cognitive brain function in the elderly. These claims will be tested by the Food and Drug Administration (FDA) before the companies are allowed to market their products for “treating” ailments or “improving” health. Until then, the companies can describe that their products “help to maintain” or “support” health. Until studies support their claims, the companies cannot ascribe direct health benefits to their products.
Why would the FDA perform tests when a cranberry company and a grape company have already conducted research on the same products?

Answer 64

The FDA is the only organization that can test if health actually improves.
Tests that are performed by any company which benefits financially are considered unreliable.
The FDA tests give reliability to the results of improved health obtained by each company.
Tests performed by the FDA follow established scientific methods, but those performed by companies do not.

Answer 65

i deleted it cuz it was not clear for u

Answer 66

Oh ok

Answer 67

All theories are hypotheses, but not all hypotheses are theories. Francis wants to know if a specific hypothesis he is researching is a theory. Which describes how Francis would know the hypothesis is a theory?
He could restate the hypothesis as a fact and no longer an explanation.
He could determine whether the hypothesis is based on repeated experiments.
He could perform the experiment and adjust data to match the desired results.
He could design and perform a new controlled experiment to test the hypothesis.

Answer 79

The statement “force equals mass times acceleration” is Newton’s second law of motion. Why is this a law rather than a theory?
It states, rather than explains, the relationship between the variables.
It cannot be proven, whereas a theory can be proven.
It may be revised if new information shows that the relationship has changed.
It was classified as a law because it is related to other similar discoveries.

Answer 80

is my pic bothering u guys

Answer 81

I think it is the first one It states, rather than explains, the relationship between the variables.

Answer 82

Why?................................ I think its between the first one and the last one.

Answer 83

Answer 84

Read the passage below. It summarizes survey information.

The Global Youth Tobacco Survey asks youth to fill in the answers to several questions about their tobacco use. In this survey conducted between 2000 and 2007, it was found that in youth ages 13-15, 12 percent of boys and 7 percent of girls reported smoking cigarettes. This information was shared and reported on the American Cancer Society website. The information was then used by several industries in the fields of health care, insurance, and education.

What is a reason that these data may be unreliable?
It is information that is too old to be considered factual.
It was found on the American Cancer Society website, and websites are unreliable.
It is information that is used for a variety of purposes and not just gathered for research.
It is from a self-reporting survey, and teens may not want to answer the questions honestly.

Answer 85
