This prokaryote belongs to the archaea domain, which is known for containing prokaryotes that can withstand scorching temperatures and extremely high levels of saline (ex: The Dead Sea)

Answer: Hardness
Igneous rock derives it's name from the Latin word ignis which means fire. It is formed when the magma after volcanic eruption gets cool and solidified either on the surface of earth crust or inside the earth crust. These rocks are characterized by their hardness. These rocks undergoes no chemical weathering but exhibit very low mechanical or physical weathering may occur. Therefore, hardness is the property which can be used to identify the origin of an igneous rock.
Mutations (changes) to the DNA within the cells.
Answer:
energy
Explanation:
because the substance moves from a low to high concentration
1. The answer is; B
This is because the soup has a higher temperature than the surrounding air. The heat will move from hotter object to the cooler object in search of thermal equilibrium. Heat transfer will only stop when the soup and the surrounding air have more or less the same temperatures.
2. The answer is; B
No mas is required because radiation (which are mainly electromagnetic waves) can transfer energy even through a vacuum. Other forms of energy transfer (such as convection and conduction)involve the transfer of vibrational motion from one molecule of matter to the next.
3. The answer is; D
The sun rays (which are electromagnetic waves that travel in photons) travel from the sun and through the vacuum of space before they reach the earth. When the photons hit the molecules that make up your skin, they energize them and cause them to vibrate more energetically. As they, differentially, lose this kinetic energy (when resuming a lower excitation state), this energy is expended as heat which you feel on your face.
4. The answer is; D
To start with, it is important to note that water is not a good conductor of heat. Therefore, as it is heated from below by the Bunsen burner, the water at the bottom of the glass gets warmer that than at the top of the glass. Warm water is less dense than cool water hence begin to rise while the cooler water from the top replaces the rising warm water. This process continues and forms convection currents until the water starts to boil.
5. The answer is; B
When the can is opened, it exposes the soup to the environment. This way the heat from the soup (due to thermal disequilibrium) transfers from the soup to the air. Because the soup is hotter, it loses heat energy to the surrounding as dictated by laws of thermodynamics.
