The correct answer is A) Memphis and Adulis.
The two places that are connected by both a land route and a sea route were Memphis and Adulis.
We are talking about two important cities during ancient Egypt times. The map shows many important ancient Egyptian cities that represented the expanded territories and dominion of Egyptian Pharaohs. Memphis was the capital of lower Egypt. It was located north of what today is Cairo, the modern capital of Egypt. It was an important city located next to the Delta of the Nile River and was an important place for trade. Adulis was located in the Gulf of Zula, in the Red Sea. It was also a place for trade that was connected to Memphis by land and sea.

Answer: Marie Curie studied the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered was also radioactive. She also found out that:
- you can exactly measure the strength of the radiation from uranium;
- the intensity of the radiation is proportional to the amount of uranium or thorium in the compound - no matter what compound it is;
- the ability to emit radiation does not depend on the arrangement of the atoms in a molecule; it must be linked to the interior of the atom itself - a revolutionary discovery!
When she realized that some uranium and/or thorium compounds had stronger radiation than uranium, she made the following hypothesis: there must be an unknown element in the compound which had a stronger radiation than uranium or thorium. Her work aroused the interest of her husband, Pierre Curie, who stopped his own research on crystals and joined the "detective work" with his wife. And Marie was proven right

Hi there, hope you’re having a good day!
The answer is thermal energy, although temperature is kind of the same thing. The ice-cream melts due to really hot temperature or thermal energy, which is the internal energy of an object.
