Why do scientists try to repeat other scientists’ experiments?
Which statement best explains the relationship between science and technology?
Which career field is an applied science?
Which statement about technology is true?
A scientist noticed that a dark-colored peppered moth is more visible on a light-colored background than a light-colored peppered moth. He wonders, “Does this difference in visibility affect the survival rate of dark moths?” Which part of the scientific method does he need to carry out next?
What is one way that early scientific practice differed from modern scientific practice?
In 1970, Hamilton Smith isolated the first restriction enzyme. Restriction enzymes are used to cut strands of DNA at specific points. This discovery led to the development of recombinant DNA, which is widely used in several scientific industries to produce proteins and hormones more cheaply and in much larger quantities than earlier methods. The change in scientific knowledge caused by Smith’s discovery most directly affected which sector of society?
A scientist who conducted an experiment obtained an unexpected result. What will she most likely do with the unexpected result?
Why is the scientific method described as nonlinear?
A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because
Which is an example of science playing a role in developing technology?
Gregor Mendel is referred to as the father of which classical science?
Which hypothesis is testable?
Biology and geology are two very different sciences, but biologists and geologists use scientific knowledge in the same way. These scientists both use scientific knowledge to
A scientist performed an experiment to test her hypothesis that a disease in horses was caused by a deficiency in an important mineral. The results did not support her hypothesis. However, some of her data showed an important change in one hormone. The scientist knew that the hormone was related to a different mineral, so she formed a new hypothesis. What is the most logical step for the scientist to take next?
Data must be considered valid for scientists to trust conclusions. Which is the best way to increase the validity of data in an experiment?
