Answer:
Hypertonic
Explanation:
In hyper-tonic solutions, the cell will shrink and crenate. The mass and volume of a gummy bear that is placed in a salt solution will decrease due to the effect of osmosis. When placed in water, a hypo-tonic solution, the gummy bear will expand in size and volume due to the water entering it.
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.
Answer:
<em>Genes are one dimensional.</em>
Explanation:
The genes are made up of segments of DNA. The DNA has a three dimensional structure as coiling and super-coiling occurs in it to give it a three dimensional structure. But genes itself are one- dimensional. Genes are the hereditary molecules.
The genes makes particular proteins. Proteins also have three dimensional structure as they undergo coiling and super-coiling.
Answer:
The Excretory System, The Reproductive System and The Endocrine System.
Explanation:
The Excretory System includes your bladder, uterus, and some of your organs. It is also called the "Urinary System". The Reproductive System includes your birth canal. This system helps to reproduce the body to have babies. The Endocrine System includes your hormones. It helps the body to depend on growth development or mood.
