Hypothesis: I believe an increase in temperature would lead to a decrease in surface tension.
Here's why: As the temperature increases, the molecular interaction between the liquids molecules becomes weaker because the hydrogen bond is the main factor for association between two molecules. It is a very weak bond to begin with, so when the temperature increases, it just further weakens it.
DNA is considered the building blocks of life.
<h3><em><u>C.</u></em><em><u> </u></em><em><u>This cell has no nucleus.</u></em></h3>
Because bacterial cell do not have a well-defined nuclear membrane. The coiled DNA particles lie naked in the cytoplasm. This is called nucleoid. While in animal cells the nucleus is surrounded by a well-defined nuclear membrane.
I think that the numerical expresion for this problem is 17.5
