Explain what it means to say that natural selection is not random
ELEN [110]
Natural Selection is not random because the organisms of a species that do not survive have a non-desirable genetic quality, a disease, injury, etc. This leaves the better organisms of a species to survive and reproduce, which creates a stronger and larger species.

aivan3 [116]

The given question is incomplete, the complete question is:

Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:

Answer:

A variable, which is under study or observation in an experiment and changes concerning the independent variable is termed as a dependent variable. Based on the given experiment, Madison is checking the influence on the progression of corrosion of metals concerning the variations in the concentration of salt. This shows that the extent of corrosion of metals is a dependent variable.  

A variable, which can be controlled or monitored like increased or decreased, and one is familiar with is termed as an independent variable. This variable is not affected by another variable, like a change in the concentration of salt is the air may exhibit an effect on the corrosion of the metal, however, the process that is, the corrosion of metals does not affect the concentration of salt in the air. Hence, the independent variable is the salt concentration in air.  

A variable that possesses the tendency to change or influence both the independent and dependent variables is known as a confounding variable. If the airspeed is higher than it will carry the salt particles at a brisk rate and speed resulting in enhanced corrosion of metals. Likewise, if the speed of air is slower, there will be a reduction in the corrosion of metals. Hence, the confounding variable is the speed of air.

What adventures does nuclear power have over fossil fuels?
Vladimir [108]

Answer:Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.
