The answer is a half-filled circle.
In the pedigree charts, squares present males and circles present females. If a female is healthy, the circle is empty (white). If a female is affected with a trait, the circle is filled-in (usually black). However, if a female is a carrier of a disease, which means that one allele is dominant and one is recessive, then the circle is half-filled.
When Amanda poured some of the liquid in a test tube, she noticed that the edges of the water curved upward, which is an example of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is evidence of cohesion.
When Amanda added table salt to the first test tube and shook it, she noted that the liquid had dissolved the solute.
All of these observations indicated the presence of covalent bonds.
Pol determined that the pH of the sample is 7, which shows the sample is neutral.
Based on all of the evidence Amanda and Pol gathered, the unknown liquid is water.
The correct answer is segmentation. <span>The annelids also known as segmented worms, are bilaterally symmetrical invertebrate organisms. Their main characteristic is a segmented body. Annelid's body consists of segments that are identical (except the first and the last one), having the same sets of internal organs and external chaetae. Septa separate the segments and enable the annelids to change the shapes of individual segments, which facilitates movement by peristalsis (symmetrical contraction movement).</span>

Explanation:
my stupid brain
Water has a high specific heat vapacity, so it takes a lot of energy to increase its temperature. water at about 4C (39F) is more densethan than water at 0C (32F).
