After an organism dies, its C-14 to C-12 ratio "remains constant".

<u>Answer:</u> Option C

<u>Explanation:</u>

Carbon dating is the evaluation of organic matter's age from the C-12 & C-14 relative proportions contained by matter. Soon after the death of organism new carbon inhalation stops. While the ratio of these carbon isotopes at the moment of death remain same as rest of the living things.

But C-14 decays by having half life of 5700 years and C-12 amount remain same in the organic matter. The ratio of C-12 to C-14 in any dead organic matter is compared to ratio in a living matter with the intention of determining the age of a formerly living thing in most precise manner.

Identify reactions in this equation 2KCIO3(s)-2KCI (s)+ 3O2 (g) A 2KCIO3 B 2KCI and 3O2 C 2KCI D there are no reactants
Delicious77 [7]
Finding the reactions in the equation 2KCIO3(s)-2KCI (s)+ 3O2 (g) A 2KCIO3 B 2KCI and 3O2 C 2KCI D.....well first look for the synthesis reactions which are if two different elements are one one side and a compound on the other side where the elements form....the next reaction you would look for would be the decomposition reaction.....and I still don't see this because if I did it would be the same as the synthesis reaction except it would be the other way around...sooo the compound of the elements would be on the right and when you add the elements it would be on the left side....the next reaction is the single displacement which I don't see in this example...the single displace me is when you are adding the elements not the left and on the right it's the same thing BUT the elements are in different order....and the last one is the combustion reaction which I do see....this is when there is adding element on both side.......so the reactions I see in this example is the combustion reaction.....hope it helps....:)

Answer:

C. Dark Moths had a survival disadvantage in industrial Dorset

Explanation:

Looking at the graph, you can see that the Dark Moth, compared to the Light Moth actually had a survival advantage.

I won't be explaining the why's to this phenomena, considering that the question is based solely on the graph.

Compare the two bars of Dorset. The Light Colored moths are represented by the green graph while the Dark colored moths are represented by the orange bar. The orange bar extends further that the green bar, showing that they recovered better than the other. So this means they were at an advantage and NOT at a disadvantage.

Murrr4er [49]

Answer:

Monomer: 2 - Amino acid

                 3 -Nucleotide

Polymer: 1 - Cellulose

               3 - Nucleic acids

Example: 1 - Carbohydrates

               2 -  Collagen

Function 1: Carbohydrates are a source of energy in the body.

Function 2: Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

Function 3: DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information

Explanation:

Monomers are single molecules that can bond with identical molecules to form polymers.

1. Glucose can combine with other glucose molecules to form starch or cellulose which results in formation of carbohydrates.

Carbohydrates are a source of energy in the body.

2. Amino acids can combine with other amino acids to form a protein chain which results in formation of collagen

Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

3. Nucleotides can combine to form nucleic acids resulting in formation of enzymes.

DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information
