When air is heated up the molecules spread out and move faster, so heat rises because it is less dense than the cooler air around it.
Answer:
The correct statements are C The pH is accurate but the solution will have excess salt. D The pH is accurate but the concentration of Tris will be incorrect
Explanation:
As the pH is finally maintained at 7 the pH for the buffer solution will be accurate but excess salt will be produced due to use of Both NaOH and HCl to make up the to 7.
As more volume of water is required at final step to make up the volume the concentration of tris will be incorrect.
Mitosis is when a DNA error, aka mutation, occurs in a body cell. When cells divide, it needs a copy of the DNA. During DNA replication, that error can cause the instructions for building proteins to differ. The change can not affect offspring. Meiosis is the same situation, but in sex cells. This can be transferred to offspring.
Science can only explain logical questions and provide answers to things that only can be scientifically proven. Things that are asked in society like religion can not be further explained. The reason why we have religion is because we have always believed in something in history. Either is was made up or concocted out of no where, humans have always believed in something. But what science can't explain is the miracles and things that have happened. Like Jesus, they can't prove that he performed miracles or was the Son of God. They can't prove he and his body ascended into heaven. Science can't explain that God is real. Yet the only thing you can do is believe in it, and trust the Bible accounts are accurately true.
