It is from a self-reporting survey, and teens may not want to answer the questions honestly.

These statements can be reliable:
1. It is information that is too old to be considered factual.
This credibility and reliability of an information doesn't intend to how old it is. It just needs to be updated and revisited. This source may be outdated but every study has a significant implication to a certain populace however subjected to its own limitations.
2. It was found on the American Cancer Society website, and websites are unreliable.
Regardless of website or article, you should consider the authors of the website to have a clue if its reliable or not since the authors come from the ACS, this would entail that they have backed up researchers and studies to support their every claim. You can ask them the title and search for them yourself.
3. It is information that is used for a variety of purposes and not just gathered for research.
Yes but every assessment and test used for research should be specifically valid and reliable for the construct aimed to be measured, the content validity and the criterion-related validity, lastly also its reliability. Since the information was specified for the certain study then it is reliable and valid, therefore is reliable yet subject to its limits.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports the evolution of earth due to chemical weathering.

hope it !

Many birth-control pills release a constant amount of synthetic estradiols and progesterone for 21 days, followed by 7 days when no hormones are ingested. which of the following statements most accurately describes the effects of birth-control pills? -birth-control pills maintain constant levels of estrogens and/or progesterone so there is no surge in lh and ovulation does not occur.-birth-control pills inhibit the development of the uterine lining so implantation of a fertilized oocyte cannot occur.-birth-control pills maintain constant levels of estrogens and/or progesterones and mask the release of the oocyte from the follicle.-the 7 days with no hormones does not allow a thick enough uterine lining to form so a fertilized oocyte cannot implant.
