What type of membrane lines the compartments of the ventral body cavity and produces a lubricant that allows organs to move agai

JulijaS [17]

Answer:

Answer is Serous membrane.

Explanation:

The serous membrane is known to be or can be described as a thin membrane usually consisting of two layers which are separated by a space filled with serous fluid, which is derived from the serum.

The serous membrane are lying the cavity of some certain internal organs of the body, such as the lung and the heart. The fluid produced by the serous membrane,[ serous fluid], serves as lubricant to reduce friction occurring from muscle movement.

Examples of serous membrane are peritoneum and pericardium.

Volgvan

Answer:

Only one of the three statement is true; and that is,

(ii.) Different metabolic end products result from the two types of fermentation

Explanation:

Fermentation is the process by which organic molecules such as glucose are broken down into smaller molecules to extract energy as ATP in the absence of oxygen.

Fermentation is carried out by many organisms including man.

In man, fermentation occurs in very active skeletal muscles such as in an athlete running. It involves the reduction of pyruvate produced from the glycolytic pathway to lactate in the muscles. The net yield of ATP from glucose breakdown to produce lactate is 2 ATP molecules.

In microorganisms such as yeast, the fermentation product of py ruvate derived from glycolysis is ethanol and carbon dioxide, CO₂. The net ATP yield in fermentation of glucose in yeast cells is also 2 ATP molecules.

From the options provided in the questions, the correct option is:

Only one of the three statement is true and that is that, ii. Different metabolic end products result from the two types of fermentation.
