are there other tests that could be used to determine if cyclohexanol is present in your product? give at least one test with so
Artist 52 [7]

One of the many tests that may be used to identify the presence of cyclohexanol in a product is that of the Lucas test.

The Lucas test is a chemical reactant test to determine the presence and level of alcoholism in a solution.  Cyclohexanol has many chemical properties as do most substances, one of which is the presence of an alcohol group.

The presence of this chemical group makes it possible to test for cyclohexanol using the Lucas test. The Lucas test will cause reactions in the presence of alcohol and transform alcohols into chloroalkanes, which tend to be nearly insoluble in aquatic solutions. Given this, a <u>positive result </u>will look like <em><u>the solution separates into a cloudy chloroalkane-containing part on top of a much clearer layer.</u></em>

In what ways are cellulose and starch similar to each other and in what ways are they different? Be specific in your comparison,
Tom [10]
By starch, I'm assuming you mean glycogen, or animal starch.
Similarities:
Both are polysaccharide molecules made from glucose molecules linked together in a long chain.
Both are storehouses of energy.

Differences:
Glycogen is made in animal cells and is the only form of starch animals can digest (unless they have certain microbes in their intestinal tracts to break down cellulose, which all herbivores need).
Cellulose is made in plant cells.

The bonds are a bit different; the molecules are isomers. Glycogen bonds with what is called an alpha 1,4 bond, meaning that the first carbon of one glucose molecule is bonded to the 4th carbon of the next glucose molecule, but in a way that puts the bonds in a shape that falls below the plane of the molecule, and allows branching.

Cellulose bonds with beta 1,4 bonds. The first and fourth carbons of adjoining glucose molecules are still connected, but the shape of the bond falls above the plane of the molecule and does not branch.

Since enzymes are specific to their substrates, the enzymes shaped to fit glycogen bonds do not fit on cellulose bonds, which is why animals cannot digest cellulose on their own. In herbivores, there are microbes in their digestive tracts which can produce enzymes to break these bonds so the glucose can be used. In carnivores and omnivores like humans, there is no enzyme to break down cellulose so it becomes 'roughage' in our diets. It passes through the digestive tract without being broken down.

If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?
ad-work [718]

Answer;

C. His mother carried at least one allele for that trait

Explanation;

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.
