The correct answer is (B) they travel faster than S waves
As the interior of the earth is incompressible, the P-waves moves much faster and transmit their energy through the medium and travel very fast as compared to the S waves. In case of S waves, they are slow because the movement of medium is perpendicular to the direction of propagation of waves’ waves travel 60 times faster than S waves. The variation in speed of travel is because the earth reacts differently to both the waves.
The answer is temperature. :)
Glucagon hormone from pancreas serves to raise the blood glucose level.
The glucagon hormone from pancreas is secreted under the conditions of lower blood glucose level. The hormone stimulates break down of glycogen into glucose to increase the blood sugar level. On the other hand, insulin hormone from pancreas serves to raise the blood glucose level when it is dropped below the normal range.
The correct answer is: D) Facts can be scientifically tested.
An opinion is, by definition, a judgment about something that is not based on facts (for example, if you prefer a certain music genre, that is an opinion). Therefore it cannot be scientifically tested. Option A is false.
Scientific theories are observations based on data that are supported by the scientific community and the general public, but most of the time those theories cannot be fully proved yet, so many years or centuries later, those theories can be debunked thanks to new theories and discoveries. Option B is false.
There are many things that scientists do not know because there is a limit to the research that can be done with our current technology, and there are many things that do not have a scientific explanation yet. So no, scientists haven't learned all they'll ever know about science. Option C is false.
Facts CAN be scientifically tested because they are proven to be true.
