2.In the messenger RNA the codon will be changed Adenine(A) is replaced with uracil(U)
3.The changed codon will cause a different amino acid to be placed. Glutamic acid is replaced with valine. This replacement will cause the protein to be deformed and have an altered function.

identify the types of mutation depicted ggc to gga
Answer:
When there is a mutation in the DNA nucleotide sequence where GGC passes into GGA, the mutation is a point mutation of the silent type.
Explanation:
A point mutation of DNA, where the cytosine nucleotide is changed to adenine, GGC to GGA, the resulting triplet mRNA is CCU, instead of GCC.
Codons CCG and CCU encode the same amino acid, which is proline (Pro), so despite the existence of a mutation, the protein that is synthesized will not have alterations in its number or sequence of amino acids.
Silent mutations are characterized by changes in a nucleotide in the DNA base sequence that do not affect changes in the coding protein, as happens in the change of GGC to GGA.
Supply-and-Demand Schedule for Cell Phones Price of Cell Phones Quantity Supplied of Cell Phones Quantity Demanded of Cell Phones $25 0 500 $50 200 450 $100 300 300 $150 400 250 $200 500 0 In the supply-and-demand schedule shown above, at the prices of _____ and _____, there is excess supply because quantity supplied is greater than quantity demanded. $25, $50 $25, $200 $150, $200
Answer:
$150, $200
Explanation:
A schedule that shows relationship between quantity supplied and quantity demanded is used to estimate the equilibrium quantity and price where there is a balance between the buyer's willingness to buy and the seller's willingness to sell.
Below this equilibrium point there is excess of quantity demanded over limited supply.
Above equilibrium there is excess supply and less demand.
According to the given schedule the equilibrium price is $100 where demand and supply are both 300 units.
The prices at which there are excess supply is given below
At $150 400 units is supplied against 250 units demanded
At $200 500 units are supplied against 0 units demanded

Do enzymes always work at the same RATE? What factors might affect the reaction RATE of an enzyme? Hint: RATE means how FAST or SLOW the enzyme works
Answer:
No
Explanation:
Enzymes is a substance that is produced by any living organisms. It acts as a biological catalyst which brings about some specific chemical reactions in the body. All enzymes in the body does not work at the same speed or same rate.
Different enzymes works at different rates. These can be affected by various factors. Different enzymes works at different specific conditions such pH, temperatures, substrate concentration, enzyme concentration, etc.
Energy in the chemical bonds of carbon-based molecules is restored or absorbed
Answer:a
Explanation:a
According to the law of conservation of energy, energy in chemical bonds of carbon based molecules is restored as energy is neither created nor destroyed.
What is law of conservation of energy?According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of mass is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

During digestion, carbohydrates are converted by enzymes into what?
Answer:
monosaccharides
Explanation:
Carbohydrate metabolism begins in the mouth, where the enzyme salivary amylase begins to break down complex sugars into monosaccharides.
During digestion, carbohydrates are converted by enzymes into simple sugars, specifically glucose.
Enzymes involved in carbohydrate digestion, such as salivary amylase and pancreatic amylase, break down complex carbohydrates, such as starch and glycogen, into their constituent monosaccharides, predominantly glucose.
This process is known as hydrolysis, where water molecules are used to break the chemical bonds between sugar molecules, resulting in the release of simpler sugar units. The glucose molecules produced through carbohydrate digestion can be further absorbed by the intestinal cells and utilized as a source of energy by the body.

2. What is a dominant allele? What is a recessive allele? Give an example of each.
Answer:
Dominant allele: A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. ... When a dominant allele is completely dominant over another allele, the other allele is known as recessive.
Recessive allele: A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. An allele is a specific variation of a gene, or specific segment of DNA. ... Different alleles produce slightly different proteins, which function in different ways.

Explanation:
In the picture, it shows plants, deer that eats grass and other trees and stuff. Plants are called autotrophs because they can use energy from light to synthesize, or make, their own food source. Many people believe they are “feeding” a plant when they put it in soil, water it, or place it outside in the Sun, but none of these things are considered food.
What does Nuclease come from? Like what’s it’s source?
A nuclease (also archaically known as nucleodepolymerase or polynucleotidase) is an enzyme capable of cleaving the phosphodiester bonds between nucleotides of nucleic acids. Nucleases variously effect single and double stranded breaks in their target molecules. In living organisms, they are essential machinery for many aspects of DNA repair. Defects in certain nucleases can cause genetic instability or immunodeficiency.[1] Nucleases are also extensively used in molecular cloning.[2]
Depiction of the restriction enzyme (endonuclease) HindIII cleaving a double-stranded DNA molecule at a valid restriction site (5'–A|AGCTT–3').
There are two primary classifications based on the locus of activity. Exonucleases digest nucleic acids from the ends. Endonucleases act on regions in the middle of target molecules. They are further subcategorized as deoxyribonucleases and ribonucleases. The former acts on DNA, the latter on RNA.[2]

Explanation:
After his initial reaction, Mr. Evil has some time to think. He calls you on the phone with a new plan. “OK,” he says. “I don’t need to be able to tunnel to the bank today, but I need to be able to do it within the next 30 years. I have access to a house that is much closer. I need to know if it will be close enough.” What do you need to know in order to answer him? Under what conditions would this new property be close enough to the bank?
Answer:
So he is asking, abstractly, from lack of context, if his house is close enough to the bank?
This makes little sense, abstractly. I mean, does he live in a post-apocalyptic Mad Max setting where he needs explosives and men or perhaps a frozen-over world where he needs large steam-powered engines to drill through the permafrost? It makes little substantiated sense.
So you need to know how much money he has, his charisma level, and the setting of the plot.
If the property is next to the bank, then it would be, by far, close enough to the bank.

what is the complimentary strand of DNA to:AGTTCCGAT
Answer:
AGTTGA
Explanation:
I TOOK THE TEST
DNA is double-stranded and the complementary strand of DNA to AGTTCCGAT is TCAAGGCTA.
What is DNA?DNA stands for deoxyribose nucleic acid. It is a polymer of nucleotides and it presents in all organisms as genetic material. It is a double-stranded molecule, and one strand is complementary to another strand. It functions as hereditary material in almost all organisms and it carries information for the development and functioning of an organism.
It constitutes ribose sugar, phosphate, and nitrogenous bases (purines and pyrimidines). Purines (adenine and guanine) are always complementary to pyrimidines.
Adenine forms double hydrogen bond with thymine, while guanine forms triple hydrogen with cytosine. Therefore, the complementary strand to AGTTCCGAT is TCAAGGCTA.
