Because water is a polar molecule, it makes an excellent solvent for polar and _________ compounds found within cells and tissues

Answers

The word missing is ionic. Ionic compounds are soluble to water. They are soluble because water is a polar molecule. Water has a positive end and a negative end. These ends attract ionic compounds. However, not all ionic compounds are able to dissolve in water.
Because water is a polar molecule, it makes an excellent solvent for polar and ionic compounds found within cells and tissues. The polarity of water (H2O) allows it to dissolve a wide array of biological materials in the body. First, it can dissolve other polar substances such as sugars and glycerol. Second, it is also a good solvent for ionic compounds that dissociate into ions, which water molecules are attracted to as well.

B. Earth is a closed system in terms of energy.
C. There is energy to support life on earth.
D. Energy is created but not destroyed in the earth system

Answers

Answer: C. There is energy to support life on earth.

The earth receives thermal energy from the sun via. radiation. This energy is captured by chlorophyll pigments of plants and other organisms to conduct photosynthesis. The sunlight energy is necessary for synthesis of food in the form of glucose. The glucose is converted into chemical form of energy as ATP which is required for respiration process in plants. Photosynthesis and respiration both are necessary processes to sustain life of plants, which further support life of other living organisms. Therefore, energy transfer support life on earth.

Which fact would support this concern?It would be difficult to convince poultry farmers to vaccinate their chickens because of the cost.It would not be possible to vaccinate all poultry being grown for consumption against the virus.Other forms of the virus have cropped up, such as H5N8 and H7N9, that would not respond to the vaccine.Vaccinations against H5N1 are proven to be effective against other viruses such as H5N8, H7N9, and H1N1.
