When you use the same histone protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (5 points) a. The histone protein has fewer basic amino acids than albumin. b. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Answer:
A. The histone protein has fewer basic amino acids than albumin
Note: The question is incomplete. The complete question is given below:
You use the Bradford (coomassie) assay to determine the concentration of a whey protein. You use bovine albumin as your standard. You determine the histone protein concentration to be 3 mg/ml. When you use the same whey protein as your standard, you determine the histone protein concentration to be 5 mg/ml. Explain the discrepancy (pick ONE answer): (2 points) The histone protein has fewer basic amino acids than albumin. The histone protein has more acidic amino acids than albumin c. The histone protein has more basic amino acids than albumin d. The histone protein contains more methionine than albumin
Explanation:
The Bradford assay measures the concentration of proteins in a a protein sample using a color change that occurs from brown to blue when the protein in the sample binds to Coomassie dye. The Coomassie dye specifically binds to basic and aromatic amino acids in the protein. A standard curve is created using absorbance data from samples of proteins of known concentrations. The spectrophotometer is set to read at 595 nm in the Bradford assay as the peak absorbance of Coomassie Blue once bound to proteins occurs at 595 nm.
The higher the concentration of proteins, the higher the color intensity and the higher the absorbance values.
Since when bovine serum albumin was used as standard, the sample protein concentration was lesser than when the protein sample was used as standard, this means that the sample protein binds less to Coomassie dye as a standard thereby giving a higher sample protein concentration than the BSA standard. Therefore, the histone protein has fewer basic amino acids than albumin.

In muscle tissue, what is the reactant of lactic acid fermentation and the product that builds up during intense exercise?
The reactant of lactic acid fermentation and the product that builds up during intense exercise is glucose.
Homolactic Fermentation in Muscle CellsLactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. Glucose is the simple sugar reactant used in this type of homolactic fermentation, instead of lactose used in the case of bacteria. This process of energy production is employed by muscle cells when oxygen levels are low, such as during periods of extreme exercise.Learn more:

Which of the following statements is true?
Mitosis produces four identical daughter cells from one parent cell.
Sexual reproduction occurs much more quickly than asexual reproduction.
Meiosis creates four nonidentical daughter cells from one parent cell.
Asexual reproduction occurs when an egg cell is fertilized by a sperm cell.
Answer:
Meiosis creates four nonidentical daughter cells from one parent cell.
Explanation:
Mitosis produces TWO identical daughter cells from one parent cell. This one is vice versa, Sexual reproduction occurs much more SLOWLY than asexual reproduction. Asexual reproduction occurs quickly. SEXUAL REPRODUCTION occurs when an egg cell is fertilized by a sperm cell.

8) Outline what you would need to know to answer the following question: of all the proteins that exist on earth at this time, what fraction of them have a known structure
Answer:
To solve this question, it is necessary to consider the number of protein structures that have been empirically verified and the number of Open reading frames predicted from sequencing data
Explanation:
The most common methodologies used to determine protein 3D structure are nuclear magnetic resonance (NMR) and X-ray crystallography. Although both methods are efficient, the determination of 3D protein structures in physiological conditions is a time and cost-consuming task. Moreover, due to recent advances in bioinformatics and sequencing methodologies, the amount of protein Open Reading Frames predicted from sequencing data (especially obtained from Next Sequencing Generation studies) is many times higher. Indeed, less than 5% of sequenced proteins have an empirically validated 3D structure.

2. Think about an animal like a rhinoceros, a deer, or an antelope. What parts of their body other than their hair must be composed of quite similar material to your nails and hair
Answer:
horns and hooves
Explanation:
horns and hooves are made of kerotin, just like nails and hair.
Keratin is the protein that composes the external layers of the epidermis. It can be found in elements like feathers, nails, and hair. Other parts of the body that might be composed of keratin are horns and hooves.
-------------------------------------
Keratin is a fibrous protein that can be found in epithelial cells that cover internal and external surfaces.
Keratin is the main component of horns, hooves, feathers, hair, and nails.
Horns are hollow and pointed structures that emerge from the skull of the animal.
Animals get born hornless. As they grow they develop these structures. Most of them complete the development near the reproductive stage of the animal.
At sexual maturity age, competitive interaction increases, and animals use them to defend themselves and hurt the opponent. Males of some species also use them to attract females.
Hooves are very developed nails that cover the ugunaltes' fingers. These animals only use the extreme of the fingers to walk.
Like all nails, hooves grow continuously and wears out as the animal walks or runs.

Answer:
For your body to cool down one method is to sweat.
Explanation: Your sweat glands release sweat, which cools your skin as it evaporates. This helps lower your internal temperature
To keep warm your body shivers and your blood pressure decrease, it brings the blood back to the heart to keep you warm, also in you blood, your hormones create glucungons that makes the liver shoot out glucose to keep you warm. To keep cool you body sweats and in you blood the hormones create something called insulin that makes you cell take in the glucose in you blood.(Fun Fact: the things that I just said are negative feedback).
