Compare the two DNA sequences. How many of the DNA codons (sets of three nucleotide bases) are different between the two sequences?
options:
A: 1
B: 4
C: 3
D: 2
2 DNA codons are different between the two sequences. So, the correct option is (D).
What are Codons?Codon is defined as a sequence of three consecutive nucleotides in a DNA or RNA molecule that codes for a specific amino acid. Some codons signal the beginning or end of translation, called start or stop (or termination) codons.
Codons are present on an mRNA or DNA. which are sequences of three nucleotides that code for a specific amino acid while the anticodons are present on tRNA (transfer RNA) molecules that help to transcribe or bring about amino acids in mRNA during the translation process.
The three-letter nature of codons that means the four nucleotides found in mRNA — A, U, G, and C which can produce a total of 64 different combinations.
Thus, 2 DNA codons are different between the two sequences. So, the correct option is (D).

fossils at used to determine what
Answer:
fossils are used to tell how long they lived what did they eat how they died habitat what they eat
Explanation:
The fossils present in a rock exposure or in a core hole can be used to determine the ages of rocks very precisely. Detailed studies of many rocks from many places reveal that some fossils have a short, well-known time of existence. These useful fossils are called index fossils.
Answer:
Fossils have been used by scientists to determine the dates of rock layers (or strata) that were laid down in succession hundreds of years ago. However, the accuracy and precision of this method depend on several conditions, such as depth, lithology, thickness and abundance of the fossils in that rock.

Scientists have found ways of inserting favorable genes into plants such as tomatoes, beans or corn to make the fruit of the plant less appetizing to insect pests. Another inserted gene allows the plant to survive heavy doses of chemical sprays that farmers sometimes use to control weeds in the fields. A farmer decides to use the genetically modified crops described above. What should the farmer using the genetically modified plants experience?
Group of answer choices
decreased crop yield
longer growing season
decreased use of pesticides
smaller growing area
Answer:
Decreased use of pesticide.
Explanation:
If there is only one answer the one above^ is the one that I would go with.
The questions asks about a GMO that makes a plant less appealing to insects and is more resilient to weed killing chemicals. Because it is less appealing to bugs to eat, there would be less of a need for pesticides. Personally, I do not feel as though there is enough evidence in the question to draw a conclusion on the other answers provided.
Farmer using the genetically modified plants experience decreased use of pesticides.
What are genetically modified plants?Genetically modified plants, also known as genetically engineered or transgenic plants, are plants whose genetic makeup has been altered through the use of genetic engineering techniques. This can be done to introduce new traits or characteristics into the plant, such as resistance to pests or tolerance to certain herbicides. The process of genetic modification involves the insertion of a specific gene or set of genes from one organism into the DNA of another organism. This can be done using a variety of techniques, such as recombinant DNA technology or CRISPR-Cas9 genome editing.
The goal of genetic modification is often to improve crop yields, increase resistance to pests and diseases, and reduce the need for pesticides and herbicides. However, genetically modified plants also raise concerns about potential environmental and health risks, as well as ethical and social issues.

Do you know the different stages through which raw agricultural materials go before they reach your table? Trace the journey of a burger bun from grains of wheat at a farm to your table. Perform online or offline research and write a report on the processes involved in manufacturing burger buns.
PLATO ANSWER
The basic raw material for making a burger bun is flour. The major steps required for turning wheat into a burger bun are as follows:
Cultivation of wheat
Harvesting of wheat
Grinding wheat to flour
Baking flour to make buns
Let’s trace the journey.
Before a burger bun reaches the table, it goes through several processes. The farmer select wheat heads when they turn golden yellow and the kernels are hard and dry. A combine harvests the wheat and packs it in sacks. The farmer then stores the wheat in a granary and eventually sells it to a wholesale trading company. The wholesaler transports the wheat to a warehouse and then sells it to a flour manufacturer. The manufacturer`s first step is to cleanse the wheat of impurities, such as weeds, seeds, dirt, small stones, and metal pieces, by using a series of giant disks and magnets. The kernels then go through a giant bath, which separates any other heavy particles that remain. It also helps cleanse the grains. Lighter materials such as husks or flakes of stalk will wash away.
After the cleaning process, the wheat goes through rollers that crack the kernel, and then huge machines use various screens to filter the wheat pieces. In the production of white flour, air currents blow the bran away from the rest of the wheat, and then the remaining pieces of wheat go through a variety of rollers that grind it into finer powder. After each grinding, the machines sift the wheat through screens—and there are more than 20 such screens. Each screen filters finer and finer particles. Finally, the manufacturer fortifies the wheat by adding special ingredients such as vitamins and iron. The manufacturer then packs, labels, and stores the ready-to-bake flour for transportation and supply.
The packaged wheat flour reaches the store racks through a variety of distributors and suppliers and by various means of transport. Once on the shelf, it is a matter of time before a consumer purchases it. Some of the packaged products may reach industrial baking organizations.
After bringing home some flour, I unpack it and then mix it with salt, water, yeast, and a few other ingredients. Before rolling it, I have to give the dough some time to rise. The yeast in the dough makes it rise through the action of tiny bubbles of carbon dioxide. I then form the dough into the correct shapes and put in the oven to bake. In the baking process, the gas bubbles exit the dough, leaving the bread soft and fluffy. After baking and cooling, the buns are ready to become parts of mouth-watering burgers.

how do commensals protect against athletes foot ? (include compete, nutrients and space in the answer)
Answer:
See explanation
Explanation:
According to Oxford dictionary, commensalism refers to; "an association between two organisms in which one benefits and the other derives neither benefit nor harm. "
There are microorganisms that are usually found on the skin surface such as Bacillus subtilis. These organisms obtain their nutrients from the skin but does not harm the body in any way.
However, fungi such as Trichophyton rubrum and T. mentagrophytes cause athlete's foot and these also grow on the skin.
Commensalic organisms protect us from athletes's foot by competing for nutrient and space with these pathogenic fungi thereby decreasing the chances of survival of the fungi.

What could happen if two of the base pairs on this strand of DNA were switched?
SC.912.L.16.3
A different protein would be made.
The strand would not be replicated.
Transcription would stop at that point.
The rest of the DNA strand would detach and unravel.
Answer: I think the answer is c
Explanation:
A different protein would be made.
If two base pairs on a strand of DNA were switched, it could lead to a different protein being produced. The sequence of DNA bases determines the sequence of amino acids in a protein. Each three-base sequence, known as a codon, codes for a specific amino acid or a stop signal.
If the base pairs are switched, the codons could be altered, resulting in a change in the amino acid sequence during protein synthesis. This change in the amino acid sequence can lead to a different protein being synthesized, potentially impacting its structure and function.

Determine the parental genotypes and proportion of offspring genotypes for locus 2. What are the genotypes of the parents with respect to locus 2 (i.e., alleles B and b)
Answer and Explanation:
Alleles are the different varieties of genes. For every gene, somatic cells have two alleles.An allele that is not expressed by an organism might be passed to the offspring of The organism provides one allele.
It is difficult to conclude which two alleles of a gene exist within the chromosomes of organisms. that organism and can express in the next generation.
The parental genotypes can be determined by PUNNETT SQUARE, in which we use two letters to signify the genotype.
As the white throat code and the red throat code are alleles.
A lowercase letter represents the recessive form of a gene (allele), and a capital letter represents the dominant form of a gene (allele). For example, for the red-throated bird, white throat is a recessive trait, and red throat is a dominant trait.
There are basic steps of using Punnett Square. Step one is to determine the parent organism genotypes then write down “mating.” Draw a p- square. For each parent, split the letters of the genotype. Then place them outside the p-square. By filling the p-square, determine the genotype of the offspring. Then summarize results.
