Comparing prokaryotes and eukaryotes
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
Answer:
The heat from the strawberries transfers to the freezer and causes the strawberries to freeze.
Explanation:
When Eric-palces some room temperature strawberries into the freezer, he is changing the temeprature of the strawberries. When the strawberries are in the room tempertaure, they are absorbing certain amount of heat.
When they are placed in the freezer they are releasing the heat to the environment and this leads to condition called as phase change. Due to this phenomenon, the heat from the strawberries transfers to the freezer and causes the strawberries to freeze.
