Answer:
Ethical concerns affect scientific research by adding boundaries to what can and cant be experimented on. An example is that its socially unacceptable to experiment on humans because its considered wrong and horrific, even at the expense of learning more about human nature and/or the human body.
Tungsten is used in light bulbs because of its high melting point.
It is also used because it has the lowest vapor pressure and greatest tensile strength.
Answer: Option (b) is the correct answer.
Explanation:
When there are more number of hydroxide ions in a solution then there will be high concentration of 
or hydroxide ions. As a result, more will be the strength of base in that particular solution.
A base is strong when it readily dissociate into its ions in the solution. When a base is strong, then it does not matter at what concentration it is dissolved in the solution because despite of its low concentration it will remain a strong base.
Thus, we can conclude that out of the given options, the statement even at low concentrations, a strong base is strong best relates the strength and concentration of a base.
Answer:
Both involve drilling into the earth and can cause environmental degradation.
Explanation:
Answer:
Explanation:
Air pollutants also affect the biosphere in turn. Ozone and acid deposition suppress plant growth; meanwhile, aerosols and their indirect effects on clouds decrease total photosynthetically active radiation (PAR) while increasing the diffuse fraction.
