Temp causes water to rise or sink through convection, and salinity affects the density of the water, so higher salinity water will contribute to deep water currents
Answer:
Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.
1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice, loss of fish stocks, birds and marine mammals, and changes in climate patterns.
2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.
3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.
4. Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.
Answer: 1. Any chemical compound that contains carbon - organic.
2. a liquid that acts to dissolve or suspend substances - solvent
3. a chemical compound that doesn't contain carbon - inorganic
4. a substance that is dissolved in a liquid - solute.
Explanation: Organic compounds are compounds that contain carbon, and mostly contain hydrogen.
Inorganic compounds are compounds that do not contain carbon.
A solute is a substance which is present in smaller proportions and dissolves or suspends in a liquid called solvent, which is present in larger proportions. The solute and the solvent together form a solution.

Hypothalamic neurons are positioned on the ventral part of forebrain. They respond to neural and physiological signals by producing neurotransmitters and peptide neuromodulators.</span>
