In a small, isolated population of piranhas, one individual is born with a synonymous mutation in a gene that codes for hemoglobin. after five generations, 5% of the piranhas carry this mutation. what is a plausible explanation for this evolution?

Answers

The most likely explanation for the evolution is the genetic drift. The genetic drift is an instrument of development in which allele occurrences of a population alter in excess of generations due to chance or called as sampling error. Genetic drift happens in all populations of non-infinite size but its effects are sturdiest in small inhabitants.

Enter your answer in the provided box. what is the value of ni for an electron that emits a photon of wavelength 95.04 nm when it returns to the ground state in the h atom?

Answers

Ni = 5 The Rydberg formula for hydrogen is 1/w = R(1/a^2 - 1/b^2) where w = wavelength in vacuum R = Rydberg constant 1.0973731568508x10^7 1/m a,b = integers greater than or equal to 1 and a < b Now we need to select the value for a. a = 1 will converge towards 91.13 nm a = 2 converges towards 364.51 nm a = 3 converges towards 820.14 nm ... Because of this, we will assume a = 1 for this problem since it converges closest to the wavelength given. Substitute known values 1/w = R(1/a^2 - 1/b^2) 1/9.504x10^-8 = 1.0973731568508x10^7(1/1^2 - 1/b^2) 10521885.52 = 1.0973731568508x10^7(1/1 - 1/b^2) 0.958824759 = 1 - 1/b^2 -0.041175241 = -1/b^2 0.041175241 = 1/b^2 24.28643927 = b^2 4.928127359 = b So Ni = 5.
Final answer:

You can determine initial value of 'n' for a photon of a given wavelength during electron transition, using Rydberg formula, with the final state being the ground state of the hydrogen atom where n1 = 1.

Explanation:

To calculate the value of 'n' for an electron that emits a photon of wavelength 95.04 nm when it returns to the ground state in the hydrogen atom, we need to use the Rydberg formula that relates the wavelength of light emitted by an electron transitioning between energy levels in a hydrogen atom:

 1/λ = R * (1/n1² - 1/n2²)

Where, R = Rydberg constant = 1.097 x 107 m⁻¹, n1 and n2 are the principal quantum numbers of the initial and final energy states of the electron(m is the ground state), and λ is the wavelength of the emitted light.

Since the electron goes back to the ground state, n1 = 1, and we know the wavelength λ = 95.04 nm. The only unknown here is n2, which we can determine by rearranging and solving the equation.

Pogil what sections of the embedded protein chain are most likely to contain amino acids with hydrophilic r-groups

Answers

Final answer:

Amino acids with hydrophilic R-groups are most likely to be located on the surface of proteins and in the exposed regions of membrane-embedded protein chains. This arrangement allows these hydrophilic side chains to interact with the surrounding water-based environments, thus maintaining the structural stability of the proteins.

Explanation:

In proteins, the sections that are most likely to contain amino acids with hydrophilic R-groups are at the surface of the proteins. This is due to the polar nature of these hydrophilic R groups. Consider the basic structure of an alpha helix and a ß-pleated sheet. In the alpha helix, there are 3.6 amino acid residues per helical turn, and the R-groups protrude outwards. The same applies to ß-pleated sheets, where 'pleats' formed by hydrogen bonding cause the R-groups to extend above and below the folds. The crucial part is, to maintain the stability of a protein, in the globular formation, the hydrophobic or nonpolar amino acids are usually located in the interior while the hydrophilic or polar amino acids are on the exterior. This arrangement permits the hydrophilic R-groups to interact with the surrounding aqueous environment.

For example, amino acids like serine, threonine, and cysteine, which are polar and have hydrophilic side chains, are frequently found on the protein's outer surface. Additionally, basic amino acids like lysine and arginine, with their positively charged side chains, also often occupy this surface position.

In membrane proteins, hydrophilic amino acids are often found in the regions of the amino acid chain that are exposed to the aqueous environment, either outside of the cell or inside the cytoplasm.

after school, Kai feels hungry and tired. He finds some sugar cookies in the cabinet and finishes the whole package. Which statement best describes the role of glucagon and insulin in this scenario?

Answers

The hormones that his body is producing creates a desire in him to give in to the craving which in this case is sugar. Glucagon is secreted in the ileum in response to carbohydrate, protein and fat. It quickly enters the circulation and is one of the fastest and shortest-lived satiety signals. It inhibits acid secretion and gastric emptying in the stomach. Further, Insulin is secreted by the pancreas in reaction to high blood glucose levels. Insulin causes cells in the liver, muscle, and fat tissue to take up glucose (and fatty acids in the case of adipocytes) from the blood, storing it as glycogen.

What type of rock would you form in this environment, showing a dried up lake bed?

Answers

In a dried up lake bed, it is expected for rock salt and evaporite minerals to be observed.

Rock salt, or halite, is the mineral form of sodium chloride ("NaCl" or table salt). Evaporite is a general term for water-soluble mineral sediments that form from the concentration and crystallization of the "mineral-containing (aqueous) solution," mostly by evaporation. They are considered as sedimentary rocks.

Lakes are freshwater bodies and thus usually form non-marine evaporites while oceans and seas form marine evaporites. Nonmarine evaporites include  blödite, borax, epsomite, gaylussite, glauberite, mirabilite, thenardit, trona, and also halite, gypsum, and anhydrite (which are more commonly found in oceans and seas).

What is the carbon cycle?

Carbon in the atmosphere is absorbed by plants to do photosynthesis, plants are consumed by animals, and this carbon accumulated in their bodies.

When an animal or plant dies this carbon is released again into the atmosphere. If not released back they become fossil fuels, and these fossil fuels are used by human activities, which pump back into the atmosphere.

Primers for PCR are chemically synthesized by commercial vendors based on specific sequences provided by geneticists. Taq polymerase, used in PCR for its heat stability, is derived from Thermus aquaticus. RT-PCR involves converting RNA to cDNA prior to PCR amplification.

Explanation:

Scientists obtain primers to be used in Polymerase Chain Reaction (PCR) through chemical synthesis from commercial vendors. Primers are short, synthetic, single-stranded DNA molecules that are complementary to the regions flanking the target DNA sequence that needs to be amplified. To design these primers, the geneticist must know sequences that are adjacent to the target DNA region. Once the forward and reverse primers are designed, they are synthesized by the vendor to match the specific sequence required for the PCR process.

The commonly used Taq polymerase in PCR is a heat-stable DNA polymerase derived from the thermophilic bacterium Thermus aquaticus, which can withstand the high temperatures during the PCR steps. The enzyme's stability is essential since the PCR involves repeated heating and cooling cycles to denature DNA, anneal primers, and extend the DNA strands.

In the case of Reverse Transcriptase PCR (RT-PCR), cDNA is synthesized from an RNA template before the PCR begins, aiming to amplify RNA sequences by converting them into DNA.

Answers

Final answer:

ATP and NADPH are synthesized during the light-dependent phase of photosynthesis.

Explanation:

The synthesis of ATP and NADPH occurs during the light-dependent phase of photosynthesis. In this phase, light energy is captured by pigments in the thylakoid membrane of the chloroplasts, and used to convert ADP and inorganic phosphate (Pi) into ATP through a process called photophosphorylation. NADPH is also produced by transferring electrons from water molecules, which are split in a process called photolysis, to NADP+.

True-breeding red petunias are crossed to pure-breeding blue petunias, and all the f1 progeny have purple flowers. if the f1 are allowed to self-fertilize and produce the f2, what is the expected phenotypic distribution of the f2 progeny?

Answers

So Whats tje question C. F1 generation is all Yy (let Y be yellow and y be green). Y is dominant to y. The F2 could be YY, Yy, Yy, or yy. 3:1

Final answer:

The expected phenotypic distribution of the F2 progeny when true-breeding red petunias are crossed with pure-breeding blue petunias, with all F1 having purple flowers, would be 75% purple flowers and 25% a mix of red and blue, under the assumption of incomplete dominance.

Explanation:

When true-breeding red petunias are crossed with pure-breeding blue petunias, and the resulting F1 progeny have purple flowers, this suggests that red and blue flower colors are co-dominant. Upon self-fertilization of the F1 progeny, we would expect to see a phenotypic distribution in the F2 generation that shows the effects of this co-dominance.

If red (R) and blue (B) are co-dominant alleles, the F1 generation will all be heterozygous (Rb), resulting in purple flowers. When these F1 plants self-fertilize, the F2 generation will have the following genotypes according to a Punnett square: RR (red), Rb (purple), bR (purple), and bb (blue). The phenotypic ratio would therefore be 1 red: 2 purple: 1 blue, or 25% red, 50% purple, and 25% blue.

However, it must be noted that if instead, one color is dominant over the other, and purple is the result of incomplete dominance, the phenotypic ratio of the F2 generation would show a different pattern. In that case, the ratio at the F2 generation would be commonly expected to be 1:2:1 according to Mendelian genetics, corresponding to 25% one parent color, 50% the blended color (purple), and 25% the other parent color.

Based on the historical context from Mendel's experiments with peas, where a similar pattern of inheritance was observed with purple and white flowers, the question suggests that the expected phenotypic distribution for the F2 generation would be 75% purple flowers and 25% a mix of red and blue flowers, assuming that the purple color is a result of incomplete dominance.

Describe the two methods suggested for projecting a nonstatistical sample result. how does an auditor determine which method should be used

Answers

Non-Statistical Sampling is the method of evaluation the competence of the evidence gathered from the auditor. Selected-sample size is referred to as non-statistical sampling. There are two acceptable methods used for projecting the amount of misstatements. They are ratio projection and difference projection.

Ratio projection is used in the non-statistical sampling and classical variable statistical sampling. It projects the misstatement amount by dividing the amount of misstatement and percentage of the dollars of the sample population.

Difference projection is defined as the average misstatements of each and every item in the sample to the overall population. This projection is executed when the misstatement is stable for the entire item, though its dollar size varies.

Results arrived from these two projections are identical, when the same proportion of items in the populations are incorporated in the sample. But, when different proportions are arrived at, then the choice between the two is based on the auditor’s judgment.

The two methods suggested for projecting a non-statistical sample result is as follows;
One of the method is applying misstatement ratio to population and difference projection.
The second method is the difference projection when misstatements are relatively constant for all items regardless of dollar size.
An auditor determine which method should be used by knowing the misstatement ratio when dollar amount of misstatements relates to dollar amount tested.

2. Chemical pollutants: Metals and solvents from the industries and factories flow in the water bodies and pollute them.For example, pesticides, etc.
3. Microbiological pollutants: These pollutants include bacteria, fungi, algae, etc. Some of these microflora are naturally present in the water and do not cause harm but if their number increases dramatically it affects human health if drunk without treatment.
