crate with a mass of 100 kg glides through a space station with a speed of 4 m/s. An astronaut speeds it up by pushing on it from behind with a force of 10 N through a distance of 5 m. The astronaut moves around to the front of the crate and slows the crate down by pushing backwardwith a force of 35 N through a distance of 10 m. After these two maneuvers, what is the final speed of the crat

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.
