While a home was undergoing a renovation, workers discovered that there was asbestos in the walls. Before any further work could be attempted, the family that owned the house had to evacuate, and specialists were brought in to remove the asbestos. Why would the house contain a substance that forced the family to be evacuated? Asbestos is not harmful, and the family was evacuated due to routine construction protocol.
Asbestos was once thought to be very useful, but now it is linked to lung cancer so the family was evacuated.
Asbestos is not harmful, but the family was evacuated so that the asbestos could be recycled for another building.
Asbestos was thought to be useful and is no longer used due to increasing costs to manufacture it.

Answers

Answer 1

Determine whether the study is an experiment or an observational study, and then identify a major problem with the study.A medical researcher tested for a difference in systolic blood pressure levels between male and female students who are 12 years of age. She randomly selected four males and four females for her study.

Answers

Answer:

The study is an observational study because the researcher is simply collecting data from the students.

Explanation:

This case is an observational study since the medical investigator is observing and comparing individuals regarding a difference in systolic blood pressure levels between males and females.

For the study to be an experiment, the researcher should do an intervention on the students, to then collect data and study the effects of it. Also, he should group the students by chance to properly conduct an experiment.

Describe how fossils help us understand the past. Provide an example.

Answers

Study of fossils has led to important new understanding about how life evolved on earth and about diseases, both ancient and modern. Fossils also help us understand past climates, including ice ages and periods that were warmer than our present climate. Knowledge from the study of fossils is helping geoscientists understand global warming and its effects. By studying the catastrophic extinction of the dinosaurs and many other life forms at the end of the Cretaceous Period, geoscientists have gained insight into the evolutionary implications of impacts by extraterrestrial objects. Investigating the physical and chemical characteristics of fossil organisms that lived during times of drastic climatic change helps us understand the implications of the changes we are making in our own environment. Information about Earth history, practical help in finding energy resources, and information that helps us anticipate the effects of possible environmental changes are not the only benefits derived from fossils. hope this helps :)
