Which of the following base pairs would be found in a cell
The base pair cytosine and guanine is found in the cell. The correct option is D.
What are base pairs?A base pair is a primary component of double-stranded nucleic acids that comprises two nucleobases that are hydrogen-bonded to one another.
They are the foundations of the DNA double helix and make a contribution to both DNA and RNA's folded structure.
Purines and pyrimidines are nitrogen bases that form hydrogen bonds between DNA strands.
Predicated by Chargaff's Rule, they associate together via complementary pairing A::T and G::C. The purines in DNA are the same as those in RNA: adenine and guanine.
The 2 significant pyrimidine bases in DNA are cytosine and thymine, which base pair with guanine and adenine. Uracil supplants thymine and base pairs to adenine in RNA.
Thus, the correct option is D.

Answer:
they are normal mutations you can never have a cure to cancer you would have to throw a lot of your DNA and genes away to have a less chance of dying but we could slow or kill cancer but no way to prevent it from happning as it happens everyday to you but those cells have a higher chance to become cancer becuase of those thing that help cells to become cancer.

The graphs show the reaction rate for an enzyme across a range of temperatures and pH. Based on these data, this enzyme functions best at what temperature and pH? *
The graph is attacged and the options is as follows:
Temperature of 27oC and a pH of 4
Temperature of 37oC and a pH of 6
Temperature of 40oC and a pH of 8
Temperature of 50oC and a pH of 10
Answer:
The correct answer would be - temperature of 37oC and a pH of 6
Explanation:
The graph 1 shows the relation between the rate of reaction for an enzyme and the temperature of reaction is been represented. In this graph the rate of eaction is highest (point from the slope starts decreasing) at the So, by the options and graph the temperature 37°C(Below 40°C) rate of reaction is maximum.
Similarly, in other graph rate of reaction and and pH has been represented in which rate of reaction is maximum at pH 6. after 6 pH the rate of reaction started decreasing.

How is an occluded front different from a cold front?
a) Warm air is pushed up during an occluded front, while cold air moves quickly during a cold front.
b) Occluded fronts cause warm air to feel dry, while cold fronts cause ground temperatures to feel cooler.
c) Warm air moves slowly during an occluded front, while cold air is cut off from the ground in a cold front.
d) Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation.
Answer:
A cold front forms at the leading edge of the colder air mass the cold front can bring thunderstorm in the region whereas the occluded front can bring strong winds and precipitation. so its probably d
Occluded fronts cause rapid changes in weather conditions, while cold fronts cause widespread cloud formation. Therefore, option (D) is correct.
What are occluded fronts?Because of their different densities, large masses of warm air and cold air do not mix when they come into contact with one another. They instead organize themselves into a front that is typically hundreds of miles long. When a warm air mass is sandwiched in between two cold air masses, the result is a phenomenon known as an occluded front. The mass of warm air rises as the masses of cool air push against one another and meet in the middle. The warm air mass is occluded, which literally means "cut off," from the ground, and pushed upward, which causes the temperature to drop. These types of fronts are known to bring blustery winds and significant precipitation.
Occluded fronts typically develop near low pressure areas that have reached their mature state.

If 100 grams of vinegar and 5 grams of baking soda are poured in a container, a small amount of gas will be produced. What will the final mass of the products be if the gas is trapped in the
container?
Answer: I think it is 105 grams
Explanation: Because classic chem and math states 100+5= 105
The final mass of the products if the gas is trapped in the container will be 105 g
From the law of conservation of matter, we understood that mass can neither be created nor destroyed during a chemical reaction but can be transferred from one form to the other.
This implies that the total mass of reactants must be equal to the total mass of products i.e
Total mass of reactants = Total mass of products
Considering the question given above, the following data were obtained:
Mass of vinegar = 100 g
Mass of baking soda = 5 g
Total mass of reactant = 100 + 5 = 105 g
From the question given above, we also discovered that the gas produced were trapped in the container.
This simply means that the total mass of reactants (i.e 105 g) will also be equal to the total mass of the products.
Thus, the total mass of the products is 105 g.

true or false , the mRNA codon UGG is the only codon that codes for the amino acid tryptophan
Answer:
true
Explanation:
Often in laboratory experiments you will want to amplify regions of the genome from several different preparations of gDNA. To do this, a mastermix will be created with all the common reagents to ensure easier pipetting, proper mixing, and controlling for variations in pipetting. Create a mastermix for running 8 identical reactions, including one negative control, each with different gDNA templates (7 total gDNA templates).
Answer:
Mastermix in PCR helps in providing faster and easier setup with pipetting, proper mixing, reduction in contamination and controlling fir variation in pipeting or tube to tube variability. Contents of PCR master mix for the desired reaction are as follows:
dNTPsPrimersthermostable DNA polymerasecofactor (MgCl2)Template DNA (for 7 samples)PCR-grade waterThe only difference in negative control for the PCR master mix is template or the different primer rest the components are the same in the master mix.
