85
Explanation:
Answer:
The answer is Temperature (Heat), Pressure and chemical activity of fluids.
Explanation:
Metamorphic rocks result from the transformation of pre-existing rocks that have undergone structural and mineralogical changes under certain physical or chemical conditions such as temperature, pressure or chemical activity of the fluids. This type of modification is known as a process called metamorphism, in which igneous rocks or sedimentary rocks, when subjected to high temperatures, pressures or active fluids, cause changes in their composition, bringing new substances to them.
Ribosomes are essential cell components that facilitate protein synthesis by translating mRNA into proteins. These proteins play various important roles in cell and organism function and survival, making ribosomes key for growth and survival.
Ribosomes are essential organs within a cell that play a significant role in the protein synthesis process. They are primarily responsible for decoding an organism's DNA into RNA, specifically an mRNA (messenger RNA), which is then used as a template for constructing proteins, a process known as translation.
Proteins produced in ribosomes function in numerous ways, including as enzymes, antibodies, and cell membrane components. Without ribosomes cell would have no way of making these essential proteins.
This is why cells need ribosomes. They are indispensable for the growth and survival of cells and organisms, as they make proteins that are crucial for cell function and growth.

The mass of the system consisting of the ice cube and the plastic cup will remain 5 grams even after the ice completely melts. This is because of the Conservation of Mass principle, which states that mass is not lost during a phase change.
The principle operating in this scenario is called the Conservation of Mass. In this specific context, this principle means that the mass of an object or a system of objects will remain the same regardless of the changes it may undergo, as long as no mass enters or leaves the system. In the case of an ice cube melting, although the physical state (phase) of the water changes from solid (ice) to liquid (water), its mass does not change.
So when an ice cube that weighs 5 grams (along with the cup) melts, it turns into an equivalent mass of liquid water. That means even after the ice has completely melted into water, the mass of the water and the plastic cup will still be 5 grams.
This is because during the phase change, only the state of the matter is altered (from solid to liquid), not its mass. The water molecules in the ice rearrange themselves and move apart during melting allowing the ice to become liquid water, but the number of molecules and thus the mass stays the same.
