1) high water temps and water acidity cause coral polyps to expel algae, causing them to turn white in color

2) acidic carbon dioxide dissolves in water, lowering that water’s pH

3) this shift in temperature is happening more quickly

4) to protect itself from the sun

5) the biodiversity of the water

Explanation:

Answer:

Explanation:

Ocean acidification refers to increase in acidity of ocean and decrement in it's pH value. Therefore, C is correct.

What is Ocean acidification?

There are a lot of new sources of CO₂ that have been created by humans in the form of different industries, automobiles etc. We humans, ourselves, are also the providers of CO₂ to our environment. CO₂ is acidic in nature, when it gets mixed with water it makes the neutral water acidic. This is what we call as ocean acidification.

The adverse effects of changing ocean's nature are-

1) Carbonate-based shells and skeletons lives will be harmed

2) Some organisms are sensitive to acidity, they can be harmed and

3) When a majority of organisms will be harmed the automatically those organisms will not survive who are at the top of the food chain.

Therefore, Ocean acidification refers to increase in acidity of ocean and decrement in it's pH value. C is correct.

Answer:

Pearson's syndrome and Zellweger syndrome

Explanation:

Pearson's syndrome occurs when there are changes in the DNA produced by the mitochondria causing an incorrect arrangement of the nitrogenous bases, which causes mutations. As a result, the person who has this disease will have a dysfunction in the bone marrow and problems in the activities of the pancreas, reduced number of red blood cells, leukocytes and platelets (which will decrease immunity and cause anemia). The disease can also compromise the kidneys and liver.

Zellweger syndrome occurs when a problem occurs in the peroxisomes of liver, brain and / or kidney cells, which function incorrectly and can cause dysmorphia in the skull, pu even in the face, visual problems, swallowing problems, seizures, anomalies in the structures of the ear and ear, hepatomegaly and deformations.

Based on the given information and analysis, options B and D are the correct statements about the city's consumption of surgical gowns during the pandemic. The new equilibrium quantity could be higher than the pre-pandemic level, and the new equilibrium price could be lower than the pre-pandemic level.

Option A: Government revenue will fall by $2,000.

This option is not entirely correct because we don't have enough information to determine the exact impact of the removal of tariffs on government revenue. However, we can assume that the removal of tariffs will reduce government revenue, but the exact amount depends on various factors such as the amount of tariffs collected before the pandemic, the current level of demand, and the extent of the tariff reduction.

Option B: The new equilibrium quantity will be 5,000 boxes.

This option could be correct because the removal of tariffs on imported medical supplies could lead to an increase in supply, resulting in a lower equilibrium price and a higher equilibrium quantity. Therefore, if the demand for surgical gowns in the hypothetical city increases due to the pandemic and the removal of tariffs leads to an increase in supply, the new equilibrium quantity could be higher than the pre-pandemic level.

Option C: The supply curve will shift to the left.

This option is not correct because the removal of tariffs on imported medical supplies would likely lead to an increase in supply, resulting in a shift to the right of the supply curve. Therefore, the statement in option C is incorrect.

Option D: The new equilibrium price for a box of gowns will be $100.

This option could be correct because the removal of tariffs on imported medical supplies could lead to an increase in supply, resulting in a lower equilibrium price. Therefore, if the demand for surgical gowns in the hypothetical city increases due to the pandemic and the removal of tariffs leads to an increase in supply, the new equilibrium price could be lower than the pre-pandemic level.

Option E: The removal of the tariff will increase demand.

This option is not correct because the removal of tariffs would likely lead to an increase in supply, which could lead to a decrease in price and an increase in quantity demanded. However, it is unlikely to increase demand directly.

In conclusion, based on the given information and analysis, options B and D are the correct statements about the city's consumption of surgical gowns during the pandemic.

Answer:

The cell walls of diatoms are made of silica. Their cell wall construction is known as frustule. It consists of two thin overlapping shells that fit into each other such as a soap box. When the diatoms die, the silica in their cell walls gets deposited in the form of diatomaceous earth.

The mitochondria of the cells are involved in the conversion of pyruvate to ATP. Therefore, option  E is correct.

Mitochondria convert pyruvate to ATP through a process known as cellular respiration, which occurs in three stages: glycolysis, the citric acid cycle (also known as the Krebs cycle), and oxidative phosphorylation.

In the first stage, glycolysis, glucose is broken down into two molecules of pyruvate. This process occurs in the cytoplasm outside of the mitochondria and produces a small amount of ATP.

In the second stage, the acetyl-CoA enters the citric acid cycle, where it undergoes a series of chemical reactions that release energy in the form of electrons. These electrons are then transferred to the electron transport chain in the third stage, oxidative phosphorylation.

In the third stage, the electron transport chain uses the energy from the electrons to generate a proton gradient across the inner mitochondrial membrane. Thus, option E is correct.

Explanation: because the lactose sinks into it

Benedict's reagent does not typically react with lactose. Benedict's reagent is a solution of copper(II) sulfate that is used to test for reducing sugars, including glucose and fructose.

When a reducing sugar is present, the reagent will change color from blue to green, yellow, or brick-red, depending on the amount of sugar present. However, lactose is not a reducing sugar, so it will not react with Benedict's reagent and will not cause a change in color. Lactose, however, is not a reducing sugar, so it will not react with Benedict's reagent and will not cause a change in color. To determine the presence of lactose in a sample, a different test, such as the lactose tolerance test, must be performed. In this test, the patient drinks a solution containing lactose and then has their blood glucose levels measured at intervals to determine how well they can digest lactose.

The underwriting costs of a new issue do not represent a tax implication in the bond refunding decision.

The bond refunding decision involves refinancing existing bonds with new ones. When considering tax implications, certain factors need to be taken into account. The call premium, which is the amount paid to redeem the existing bonds before their maturity date, can have tax implications. The cost savings from lower interest rates can also have tax implications, as they can affect the deductibility of interest expenses. However, the underwriting costs of a new issue do not directly relate to tax implications. Underwriting costs are the fees associated with the issuance of new bonds, which are typically paid to investment banks or underwriters. These costs are not directly linked to taxes but rather represent expenses incurred in the process of issuing new bonds. Therefore, the correct answer is C. Underwriting costs of a new issue do not represent a tax implication in the bond refunding decision.

Answer: Oxygen Isotopes!

Explanation: I just took the quiz and I got it correct!

The first reaction in the image is hydrolysis reaction and the second one is condensation reaction.

The process of changing one group of chemical compounds into another is referred to as a chemical reaction.

A condensation reaction is a kind of chemical reaction in organic chemistry where two molecules join to produce one molecule, typically with the loss of a minor molecule like water.

The process is also referred to as a dehydration synthesis if water is lost during it.

The hydrolysis reaction is the reverse of a condensation reaction and involves two molecules (often H2O) reacting to form two distinct molecules.

Hydrophobic compounds can't dissolve or mix with water. Hydrophobic substances are those that naturally repel water, resulting in the formation of droplets.

Thus, as in the first reaction, water molecule is used to break the bond so it is hydrolysis, as well as the removal of water molecule in second reaction shows condensation reaction.

Answer:

All of the above. I think this is the answer.

Answer:

Explanation:

To determine whether the population is in Hardy-Weinberg equilibrium (HWE) for the Ab locus, we need to compare the observed genotype frequencies with the expected frequencies under HWE assumptions. The expected genotype frequencies under HWE can be calculated using the allele frequencies observed in the population.

Let's assume that the Ab locus has two alleles, A and B. We'll denote the allele frequencies as p and q, respectively, and the expected genotype frequencies under HWE as p^2 (AA), 2pq (AB), and q^2 (BB).

Given the genotyping data, we can analyze the observed genotype frequencies and calculate the expected frequencies. Let's say we obtained the following counts:

AA: 45 individuals

AB: 60 individuals

BB: 15 individuals

To determine the allele frequencies, we can calculate the allele counts. Let's denote the frequency of allele A as p and allele B as q.

Count(A) = 2 * AA + AB = 2 * 45 + 60 = 150

Count(B) = 2 * BB + AB = 2 * 15 + 60 = 90

Total count = Count(A) + Count(B) = 150 + 90 = 240

p = Count(A) / Total count = 150 / 240 = 0.625

q = Count(B) / Total count = 90 / 240 = 0.375

Now, we can calculate the expected genotype frequencies under HWE:

p^2 = (0.625)^2 = 0.390625

2pq = 2 * 0.625 * 0.375 = 0.46875

q^2 = (0.375)^2 = 0.140625

To determine whether the population is in HWE, we can perform a chi-square test using the observed and expected genotype frequencies.

Observed:

AA: 45 individuals

AB: 60 individuals

BB: 15 individuals

Expected (calculated above):

AA: (0.390625) * 120 = 46.875

AB: (0.46875) * 120 = 56.25

BB: (0.140625) * 120 = 16.875

To conduct the chi-square test, we compare the observed and expected frequencies for each genotype and calculate the chi-square statistic:

Chi-square = Σ [(Observed - Expected)^2 / Expected]

Calculating for each genotype:

AA: [(45 - 46.875)^2 / 46.875] = 0.07602

AB: [(60 - 56.25)^2 / 56.25] = 0.26765

BB: [(15 - 16.875)^2 / 16.875] = 0.10741

Summing the values:

Chi-square = 0.07602 + 0.26765 + 0.10741 = 0.45108

Degrees of freedom (df) = Number of genotypes - 1 = 3 - 1 = 2

To determine whether the population is in HWE, we compare the chi-square statistic with the critical value from the chi-square distribution table for the given significance level and degrees of freedom. If the calculated chi-square value exceeds the critical value, we reject the null hypothesis of HWE.

Alternatively, we can use statistical software or an online chi-square calculator to obtain the p-value associated with the calculated chi-square value. If the p-value is below the chosen significance level (e.g., 0.05), we reject the null hypothesis.

Further analysis:

If the population is not in HWE, it suggests that there are deviations from the expected genotype frequencies. The deviations could indicate factors such as non-random mating, genetic drift, selection, mutation, or migration.

To explore the deviations further and understand the factors contributing to the population's deviation from HWE, additional investigations can be conducted. These might include:

1.  Investigating mating patterns: Assessing whether individuals are preferentially mating with individuals of certain genotypes or from specific breeding units.

2.  Genetic drift: Analyzing the population size and potential bottlenecks or founder effects that could contribute to deviations from HWE.

3.  Selection: Examining whether natural selection is acting on the Ab locus, leading to deviations from expected genotype frequencies.

4.  Mutation and migration: Assessing the potential impact of new mutations or migration from other populations on the observed genotype frequencies.

By conducting these additional investigations, we can gain a better understanding of the factors influencing the population's deviation from HWE and further test the original hypothesis.

The physical difference between the two stars of spectral class B5 is that the star with broad hydrogen lines has a higher temperature and faster rotation compared to the star with narrow hydrogen lines.

The width of the hydrogen lines in a star's spectrum provides information about its physical properties. In this case, the star with broad hydrogen lines indicates a higher temperature and faster rotation compared to the star with narrow hydrogen lines.

The broadening of spectral lines is primarily caused by two factors: temperature and rotation. Higher temperatures lead to increased thermal motion of particles in the star, resulting in broader spectral lines. Therefore, the star with broad hydrogen lines has a higher temperature than the star with narrow hydrogen lines.

Additionally, the rotation of a star can also affect the broadening of spectral lines. A faster rotation produces a larger Doppler shift, which leads to broader lines in the spectrum. Therefore, the star with broad hydrogen lines is likely rotating at a higher speed than the star with narrow hydrogen lines.

Overall, the presence of broad and narrow hydrogen lines in the spectra of these B5 stars suggests differences in temperature and rotation, indicating variations in their physical characteristics.

Explanation:

Feeder groups are categories of organisms based on their primary source of food. The most common feeder groups are: carnivores, herbivores, omnivores, insectivores, frugivores, granivores, nectarivores, planktivores, and detritivores. Carnivores feed primarily on animal tissue, herbivores feed primarily on plants, and omnivores feed on both animal and plant tissue. Insectivores feed primarily on insects, frugivores feed primarily on fruits, granivores feed primarily on grains, nectarivores feed primarily on nectar, and planktivores filter small organisms from water. Detritivores feed primarily on decaying plant or animal material. Some organisms, such as parasites, feed on a live host organism. It is important to understand these feeder groups and their associated diets in order to better understand the ecological roles and relationships of different organisms in their ecosystems.
