Answer: The correct answer is : Living systems depend on the polarity of water, because since water is polar it has an unevenly distributed charge, this means that water molecules are slightly positive and negative, for this reason water is a good solvent, this characteristic is essential in organisms. For example, sugars and other nutrients are dissolved so that the blood cells can carry it to cells in the body. If sugars weren't dissolved, they couldn't reach cells. Water also attracts or is attracted to other molecules and polar ions, including many biomolecules, such as sugars, nucleic acids and some amino acids.
Answer:
Directionality
Explanation:
Directionality can be a problem in correlational research. This can occur when a study shows that two variables are related, but the researcher has a hard time understanding which variable is the cause and which is the effect. In this example, the researcher might not know whether people who are more exposed to violence become more violent, or whether violent people are more likely to seek out violence in media.
well here's why
Since opposite charges attract each other, the negatively charged electrons are attracted to the positively charged protons. Tell students that this attraction is what holds the atom together. Explain to students that in a hydrogen atom, the negatively charged electron is attracted to the positively charged proton.
hope this helps
