Which of the following statements explains if the reaction is endothermic or exothermic? The change in enthalpy is +180 kJ, so it is an endothermic reaction.
The change in enthalpy is −180 kJ, so it is an exothermic reaction.
The activation energy is lower than the change in enthalpy, so it is an exothermic reaction.
The activation energy is higher than the change in enthalpy, so it is an endothermic reaction.

56.16 gregor mendel was the first scientist to use statistics to analyze scientific data. before mendel's experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. after mendel's discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. this is an example of pls

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
