The process of making an exact copy of the DNA in a cell before mitosis is called replication.
The term used to describe the process of making an exact copy of the DNA in a cell before mitosis begins is replication. Replication occurs during the S phase of the cell cycle, where the DNA molecule unwinds and each strand serves as a template for the synthesis of a new complementary strand. This results in two identical copies of the DNA molecule, ensuring that each daughter cell will have the same genetic information as the parent cell.

true or false
Answer:
True
Explanation:
The nitrogen fixation is a process that involves conversion of atmospheric nitrogen to nitrates in the soil. This process is mainly performed by nitrogen-fixing bacteria present in the soil.
The nitrogen fixation is important for plants and animals. The nitrogen present in the atmosphere cannot be used directly by animals and plants. The nitrogen is main constituent of chlorophyll that is required for the process of photosynthesis and for amino acids that synthesize proteins. Thus, Nitrogen fixation makes nitrogen gas useful to crops.

When forming bonds in metal, metal releases its valence electron to produce positive ions.
Free radicals are electrons that exist in metallic bonds. It is simpler to alter the metal's shape because the electrons may easily flow between the atoms.
Whenever they establish bonds, metal atoms quickly surrender their valence electrons to produce positive ions.
Therefore free electrons found in metal alter the shape, due to the flow between the atoms.
