Organisms living today do not share ancestry with older, simpler life-forms. true false

Answers

The best and most correct answer among the choices provided by the question is the second choice. The statement "Organisms living today do not share ancestry with older, simpler life-forms." is False. I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:

False

Explanation:

The organisms that live today share ancestry with older and simpler life forms. This is totally true information and it is through this ancestry that living beings are able to share genetic factors with each other.

Ancestrality is the term given to the process that allows the emergence of a descendant with genetic modifications, having as a point of origin a simpler and older form of life. An example of ancestry can be seen between the human being and the chimp, where both are descendants of the same older and simpler ancestor.

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 an environmental consequence of importing resources into the United States?a. air pollution
b. habitat loss
c. oil spills
d. all of the above

Answers

The correct answer should be C. oil spills. If you take oil into the United States then there's bound to eventually be an oil spill. Habitat loss can occur when you deforest lumber in order to give it to the US because they pay you for it so the animals in your forest lose homes. Air pollution is because of all the fuel used to transport things into the US.

Answer:

D is the correct answer

Explanation:

Which of these proteins in mammals show only primary and secondary structures?Oxytocin
Keratin
Hemoglobin

Answers

The correct answer is keratin. Proteins like keratin are made up of multiple peptide chains (polypeptide); these are group of amino acids joined by peptide bonds. The sequence of amino acids in a protein is the primary structure while the specific shape in which it is folded (alpha or beta) is called the secondary structure.
