Which of the following statements about maltose are correct?

Biology
2 answers:
amm18123 years ago

Answer: The three statements are correct.

Explanation: Maltose is a disaccharide consisting of two D-glucose (monosaccharide) units joined covalently by an O-glycosidic bond between carbon 1 (C-1) of one glucose unit and carbon 4 (C-4) of another glucose unit. O-glycosidic bond is formed when a hydroxyl group of one sugar reacts with the anorexic carbon of another sugar molecule.

Maltose dissolves in water, therefore it is soluble in water.

Maltose is a reducing disaccharide because the anomeric carbon atom (C-1) of the second glucose residue can be oxidized to a carboxyl group. Thus maltose is reducing sugar because it is capable of reducing ferric or cupric ion. Reducing sugars reduce cupric Cu2+ or ferric ions Fe3+ and have their carbonyl carbon oxidized to a carboxyl group.

Answer:

All the three statements about maltose are correct.

Explanation:

1) Maltose is formed from the combination of two same type of monosaccharide i. e. two glucose molecules.

2) Maltose is soluble in water. Its solubility value is 1.080 g/mL.

3) Maltose is a reducing sugar because it act as a reducing agent due to the presence of aldehyde group with glucose molecules.

Additional compounds can be added to agar before sterilization (or sometimes after). an example of this is "milk agar," in which
Marat540 [252]

The lactose-digesting bacteria like to grow on milk agar .Bacillus cereus growth and survival were examined during the production of cheese of the Gouda variety. Approximately 102 B. cereus spores per milliliter of cheese milk were intentionally added to pasteurized milk before it was used to make the cheese in the pilot plant.

"milk agar," in which 2% nonfat powdered milk is added to the agar base. lactose-digesting bacteria like to grow on milk agar. Surface plating on B. cereus selective medium was used to count B. cereus, while lactic acid bacteria were counted on lactic agar and MRS agar (de Man-Rogosa-Sharpe). Samples of the milk before renneting, the curd at cutting, the half-whey removal, the final whey removal, the hooping of the curd, the cheese after pressing, the cheese after brining, after one week, after two weeks, after four weeks, and after six weeks were all taken for microbiological analysis. The growth of lactic acid bacteria during cheese production was unaffected by B. cereus.

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cell
Marrrta [24]

Answer:

M phase: 4.8 hr

Prophase: 2.4 hr

Prometaphase: 0.72 hr

Metaphase: 0.24 hr

Anaphase: 0.84 hr

Telophase: 0.6 hr

Explanation:

Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase,  Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:

M phase: 40/200 = 0.2 x 24 hr = 4.8 hr

Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr

Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr

Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr

Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr

Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr
