<h3><u>Answer;</u></h3>
The law of independent assortment
<h3><u>Explanation;</u></h3>
- The Principle of Independent Assortment illustrates how different genes individually separate from one another when reproductive cells receive.
- Independent assortment of genes and their similar traits was first mentioned by Gregor Mendel in 1865 during his studies of genetics in pea plants.
- When two or more characters are acquired, individual hereditary factors classify independently during gamete production, giving distinct traits an equal opportunity of befalling together.
<u>Answer</u>: Cystic fibrosis is a genetic disorder that causes thick mucus secretions.
<u>Explanation</u>:
- <em>Cystic fibrosis</em> is a genetic disorder caused by mutations in a gene that makes a protein called CFTR (cystic fibrosis transmembrane regulator).
- The CFTR protein normally functions as a channel for transport of chloride ions in cells responsible for mucus production.
- A person suffering from cystic fibrosis produces abnormal CFTR protein or no CFTR protein at all.
- This is the reason that thick, sticky mucus is produced instead of the thin, watery kind.
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.
