Answer:

Their structure is related to their function.

Explanation:

Protein structure is related to their function. Therefore, the correct option is option D among all the given options.

Proteins are huge biomolecular and macromolecular structures made up of one or even more long amino acid residue chains. Proteins serve a wide range of roles inside animals, including catalyzing metabolic events, DNA replication, reacting to stimuli, provides support to organisms and cells including transporting chemicals.

Proteins differ largely in their amino acid sequence, which is determined by the genetic code from their genes and generally culminates with protein folding into such a particular 3D structure that dictates its function. Protein structure is related to their function.

Therefore, the correct option is option D.

The reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

If you added 40.0 mL of Vitamin C stock solution instead of 25.0 mL when preparing Solution, the reaction rate is affected because of the lower amount of reactant for the chemical reaction. If the reactants are present in larger amount then the products are also produced in large concentration.

So we can conclude that the reaction rate is affected if the vitamin C is added in lower quantity due to lower amount of reactants.

Fission is when the parent atom splits into two daughter products. Whereas atom with a mass number is lower by 4 and an atomic number is lower by 2.

Fission outcomes emit beta radiation, while actinides mainly emit alpha radiation. Many of each also radiate gamma radiation.

The beta decays form an isobaric, fission-product decay chain for each mass number.

Thus, Fission is when the parent atom splits into two daughter products.

The man has been missing for two days. The average temperature the previous 48 hours was 50° fahrenheit. 12-24 hours is the time. body was discovered.

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is a part of several measurements that are used to compare the length of events or the gaps between them.

To compare how long they last, to order events, and to measure how quickly things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as an a fourth dimension. A body was discovered in the woods. The man has been missing for two days.

Explanation:

On the reactant side, XeO3 is a strong oxidizing agent. It can be a solid or gas. Most likely it is in a solid state.

H+ and Br- combine to form HBr which is a weak acid. So H+ and Br- are in an aqueous state.

On the product side, both Br2 and Xe are not very soluble in water. They will be in gaseous state and H2O is water i.e. liquid state.

If 30 grams of KCl is dissolved at 10°C, 14 g of KCl should be added to make a saturated solution at 60 °C.

A saturated solution is a solution in which there is so much solute that if there was any more, it would not dissolve. Its concentration is the same as the solubility at that temperature.

At 10 °C, the solubility is 31.2 g KCl/100 g H₂O.

30 g KCl × 100 g H₂O/31.2 g KCl = 96 g H₂O

At 60 °C, the solubility is 45.8 g KCl/100 g H₂O.

96 g H₂O × 45.8 g KCl/100 g H₂O = 44 g KCl

44 g - 30 g = 14 g

Based on the fgiven K_{a} values of the acids, the equilibrim concentrations of[tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex] is dtermined using ICE tables.

An acid dissociation constant, [tex]K_{a}[/tex] of an acid is a measure of the strength of the acid in solution. The larger the [tex]K_{a}[/tex] value of an acid, the stronger the acid, therefore, acid dissociation constants are usually apply to only weak acids because strong acids have exceedingly large [tex]K_{a}[/tex] values.

It is written as a  qoutient of the equilibrium concentrations of the aqueous species in the acid solution.

For the weak acids such as [tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex], their equilibrim concentrations are determined using their [tex]K_{a}[/tex] values and an ICE table.

The pH of solutions are estimated using indicators such as methyl orange, methyl red and phenolphthalein. The colors of indicators change according to the pH of the solution

Acidic solutions have pH less than 7 while alkaline solutions have pH greater than 7.

Therefore, acids have low pH and weak acids have low [tex]K_{a}[/tex] values.

Answer:In general, the gross composition of cow's milk in the U.S. is 87.7% water, 4.9% lactose (carbohydrate), 3.4% fat, 3.3% protein, and 0.7% minerals (referred to as ash).

Explanation:

i got it ccorerct

Answer:

The milk of goats and sheep is similar in composition to that of cows.

Milk protein consists mainly of casein, and it exists in several classes: α, β, etc. If milk pH falls below 4.6, the casein precipitates. Although casein represents 80–85% of total milk protein, when precipitation occurs, the liquid portion is referred to as whey.

The remaining proteins are found in whey, and they include serum albumin, immunoglobulins, α-lactalbumin, etc. Milk carbohydrate is lactose, and its content is fairly consistent among breeds of milk cows at around 5.0%.

lactose is the main sugar; smaller quantities of glucose and citric acid exist. The fat content varies between ca. 3.5 and 5.0% depending upon cattle breed.

The ash content of around 0.7% consists of a relatively high level of Ca2+ and a lower level of Fe2+.

The pH of fresh whole milk is around 6.6 but it may reach ca. 6.8 from a cow that has mastitis.

Mastitis is an infection of the udder that is most often caused by Streptococcus agalactiae and S. Uberois but sometimes by Staphylococcus aureus or Streptococcus dysgalactiae.

Fresh milk of mastitis cows mainly has leucocytes (white blood cells) >106/ml as compared to nonmetastatic milk which has 70,000/ml leucocytes.

Milk contains a very adequate supply of B vitamins with pantothenic acid and riboflavin being the two most abundant. Vitamins A and D are added for human consumption, and their presence has no known effect on the activity of microorganisms.

Overall, the chemical composition of whole cow’s milk makes it an ideal growth medium for heterotrophic microorganisms, including the nutritionally fastidious Gram-positive lactic acid bacteria. However, the milk microbiota utilizes these constituents and brings about its spoilage.
