In 1963, maarten schmidt of the california institute of technology found the most distant object that had ever been seen in the universe so far. called 3c273, it emitted electromagnetic radiation with a power of 2×1013 suns, or 100 times that of the entire milky way galaxy! schmidt called 3c273 a "quasi-stellar radio source," a name that was soon shortened to "quasar." since then, astronomers have found many quasars, some substantially more powerful and distant than 3c273. quasar 3c273 is moving away from earth at about speed 0.16c. the sun is 1.5×1011mfrom earth and emits energy at a rate of 3.8×1026j/s caused by the conversion of 4.3×109kg/s of mass into light and other forms of electromagnetic energy. the hubble constant is
h=70.8km/smpc=70.8103m/s3.09×1022m= =22.9×10−19s−1
estimate the mass of 3c273 that is converted to light and other forms of radiation each minute. by comparison, the mass of earth is 6×1024kg.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution. b.)biological evolution states laws that are part of mendel’s theory of genetics. c.)mendel’s genetics replaced darwin’s entire concept of biological evolution. d.)biological evolution is a law that explains why all genetics exist.
