Explanation:

Glucose derivatives can produce a number of different molecules, including sugar acids. Below are three sugar acids. (1) Indicate which carbon has been oxidized in glucose to produce the sugar acid and (2) match the function of the sugar acid by selecting the letter associated with a description. This will require you to investigate functions!a. This sugar acid is used as a substrate in glucuronosylation reactions to modify other insoluble molecules, forming glucuronides that are water soluble and can be more efficiently eliminated from the body as waste. b. Produced in small amounts in mammals, but found in higher amounts in fruits, including apples and grapefruits. This sugar acid has been shown to limit hormone-dependent cancers through inhibition of β-glucuronidase. c. Found in honey, where the pH is kept acidic to inhibit growth of microorganisms. This sugar acid is produced by the enzyme glucose oxidase and serves to enhance flavor.
i. Gluconic Acid: oxidation at __________, function description letter ____ ii. Glucuronic Acid: oxidation at _________, function description letter ____ iii. Glucaric Acid: oxidation at _________, function description letter ____

Answers

Gluconic Acid: oxidation at carbonyl (1st) carbon, function description letter c.
Glucuronic Acid: oxidation at last (6th) carbon, function description letter a.
Glucaric Acid: oxidation at both carbonyl and last carbon, function description letter b.

According to the site of oxidation, sugars are classified into different groups. The name of the sugar suggest which group it belongs:
1. Aldonic acids - carbon is oxidized at carbonyl carbon -  e.g. gluconic acid.
2. Uronic acids - carbon is oxidized at last carbon - e.g. glucuronic acid. 
3. Aldaric acids - carbon is oxidized at both carbonyl and last carbon - e.g. glucaric acid.

Which of the following is not a factor in determining if an animal should be placed on the endangered species list? the animal's fur is valuable to humans. the animal's habitat is threatened. the animal is predated on significantly by other animals. the animal is visually appealing.

Answers

Answer:

The correct answer would be the animal is visually appealing.

Endangered species are those which are on the verge of extinction in near future and require immediate steps for their conservation.

The principal threats to the species are:

  • Loss of habitat due to human intervention such as deforestation, building of dams, agriculture practices et cetera.
  • Spread of invasive species.
  • Increased pollution and global warming.
  • Unsustainable hunting of animals for products like fur, tusks, meat et cetera.
  • Diseases  

The visual appearance of an animal is not a threat to the organism and thus, it does not determine if an animal should be placed on the endangered species list.

The answer is
the animal is visually appealing
