Hope that helps.</span>
i think i took the same test as you and it tis decreased eutrophication
Answer:
d) Chemical composition of its outer regions
Explanation:
Spectroscopy is the study of spectral lines, it's an important part of studying the chemistry that goes on in stars and interstellar clouds, spectral lines can give relevant information because every atom or molecule gives off light at a specific frequency, thus, astronomers can look for gas containing a particular atom or molecule by tuning the telescope to one of the gas's characteristic frequencies. Therefore, we can know the chemical composition or a star's outer regions analyzing the spectral lines.
Even though the spectral shape of a blackbody continuum depends on the temperature of the object an there's a relationship between an object’s temperature and the peak of its spectrum, we don't consider this answer as correct because we are not measuring spectral lines but the continuum.
I hope you find this information useful and interesting! Good luck!
greater dependence on technology as a means of survival
Explanation:
One of the things that can occur as a result of technological progress is the greater dependence on technology as a means of survival.
- Technology is simply the practical application of science. It is science at work.
- Improved technology shifts attention to the deployment of innovations as life hacks.
- Robots nowadays have become errand boys and are gradually disrupting the ways in which work is done.
- Technology will reduce the time spent relating with others as people will prefer social media and games.
- Our world will become synthetic and not based on agriculture again if technology growth continues to accelerate.
