Not enough info, but I'd go with:
B) hydrogen peroxide
I believe you meant to say is this mistake called a base pair and if that is your question then no. it would be called Mutation. But you can double check that answer.
The answer is confirmation bias. This is the tendency to look for evidence that will confirm ones hypothesis and ignoring anything else that does not lead to the hypothesis. In this situation confirmation bias is evident due to the fact that you look for anything that confirms your hypothesis and ignore anything else that does not point to drug abuse.
Solar- technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation.
Hydro- a hydraulic turbine converts the energy of flowing water into mechanical energy. A hydroelectric generator converts this mechanical energy into electricity
Tidal- energy is a form of hydropower that works by harnessing the kinetic energy created from the rise and fall of ocean tides and currents, also called tidal flows, and turns into unusable electricity
Wind- turns the propeller like blades of a turbine around a rotor, which spins a generator, which creates electricity
OTEC- plants pump large quantities of deep cold seawater and surface seawater to run a power cycle and produce electricity
Biomass- is burned in a boiler to produce high-pressure steam. This steam flows over a series of turbine blades, causing them to rotate. The rotation of the turbine drives a generator, producing electricity
Geothermal- power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth’s surface. The steam rotates a turbine that activates a generator, which produces electricity
The number is different than the number of chromosomes because us humans normally contain 23 pairs of chromosomes which is a total of 46 chromosomes in each cell. A change in the number of chromosomes can cause problems with growth, development, and function of the body systems.
