Answer:
The greenhouse effect is the production of harmful gases that harm the atmosphere.
Humans can reduce the level of greenhouse gases by opting for alternate technologies or reducing their carbon emissions.
Explanation:
The greenhouse effect is the process of heating the earth's atmosphere by trapping the Sun's energy, thereby making the atmosphere hot. This natural process of trapping the heat is caused by numerous gases like methane, carbon dioxide, water vapor, and other gases. It's from this process that the atmosphere produces bad gases that damage the earth.
The reduction of the effect can be reduced by humans if they reduce their consumption of resources or energy. Moreover, shifting to alternate technologies that use lesser or no gasoline will also help in the reduction of greenhouse gases.
Answer:
Sodium chloride removes proteins from DNA and helps in DNA precipitation.
Explanation:
The Deoxyribonucleic acid (DNA) is negatively charged due to the highly polar phosphate groups that make up the phosphate backbone. The molecules of water are also highly polar and they have positive charge, thereby water molecules interact with the negative charges of the DNA. The sodium chloride generates temporary attraction forces between sodium (positive) ions and the DNA backbone (negative), thereby DNA can be disassociated from the aqueous layer. Moreover, sodium chloride helps to remove proteins (histones) that bound to DNA and also helps to maintain proteins in the aqueous layer.
Species - A group of organisms that interbreed and produce fertile offspring. population - A group of organisms of the same species living in the same area at the same time, and which are capable of interbreeding. community - A group of populations living and interacting with each other in a common habitat.
