Sorry but the only thing i know is the first one which is cell membrane
Answer:
mutation in DNA
Explanation:
Mutations are changes in the genetic code that can occur in many ways. Each time a cell divides, say, DNA must be copied into two copies, one copy for each new cell. Although this copying is very precise, it is still not perfect - for about every billion accurately copied databases, one is mistranslated.
Another source is DNA damage, which can occur spontaneously through the normal life of the cell, or through external toxins or negative influences (ultraviolet radiation, for example). Through evolution, cells have developed a very complex system for repairing changes in DNA, but these systems not only have limitations but can sometimes cause additional errors themselves.
Reducing the activation energy can increase the rate of a reaction. Reducing the activation energy would mean that less energy is required to process a reaction, whereas increasing activation energy would require more energy to process a reaction.
Answer:
B
Explanation:
The rest are being scattered and transmitted however B is going up creating a V shape.
Think b is the right answer
