The statement is true. Damage to this serous membrane can cause the lungs to collapse.  In conclusion, damage to this serous membrane can cause the lungs to collapse.

The pleural membrane or serous membrane is a delicate and protective serous membrane that covers the lungs and internal chest wall. It has two layers: a parietal pleura that lines the chest wall and a visceral pleura that envelops the lung. The pleural cavity, a potential space filled with serous fluid, is formed by these two layers of serous membranes. Pleural effusion, pleurisy, and pneumothorax are common diseases that can affect the pleural membrane.

Pneumothorax is a condition that occurs when air enters the pleural cavity, causing the lung to collapse. Damage to the pleural membrane can cause pneumothorax. It can happen if the pleural membrane is pierced by a rib or a broken rib, or as a result of chest injury from blunt trauma, such as in a car accident or a hard fall. This injury can cause a hole in the pleural cavity, allowing air to escape from the lungs, causing it to collapse.

The global variation in sea level brought about by change in the volume of water occupying the ocean basins that is eustasy.

Sea level rise is therefore a climate change phenomenon that increases the volume of ocean water, primarily as a result of the melting of ice sheets and glaciers and the thermal expansion of water. Global sea levels are rising as a result of human-induced global warming, and the recent rate of rise is unprecedented in the last 2,500 years. Sea level rise is mainly caused by two factors related to global warming.

As the planet warms sea levels rise for two reasons. First, as temperatures rise land-based ice such as glaciers and ice sheets melt and the melted water flows into the sea causing sea levels to rise. Second warm water expands and takes up more space than cold water increasing the volume of ocean water. The major physical impacts of sea-level rise include coastal erosion, delta inundation, and flooding and loss of many wetlands and marshes.

The calcium channels in the sarcoplasmic reticulum closes due to the rising concentration of cytosolic calcium and hence, the the calcium release eventually stops.

The sarcoplasmic reticulum's calcium channels close when the amount of cytosolic calcium increases. A decrease in cytosolic calcium concentration causes calcium to separate from troponin and causes tropomyosin to reposition itself. The sarcoplasmic reticulum releases calcium ions in response to the action potential, activating troponin and inducing muscle contraction.

The brain impulses cause the release of neurotransmitters, which reduce the voltage difference across cell membranes and result in depolarisation. An action potential is then produced once the depolarization travels through the T tubules and along the sarcolemma.

the answer you are looking for is B. Glucose is broken down into two pyruvate molecules.

this process occurs during glycolysis

Glucose is broken down into two pyruvate molecules.

What is Krebs cycle ?

A sequence of reactions in the living organism in which oxidation of acetic acid or acetyl equivalent provides energy for storage in phosphate bonds (as in ATP) — called also citric acid cycle, tricarboxylic acid cycle.

What is the end product of Krebs cycle ?

At the end of the Krebs cycle, the final product is oxaloacetic acid. This is identical to the oxaloacetic acid that begins the cycle. Now the molecule is ready to accept another acetyl-CoA molecule to begin another turn of the cycle.

In which process glucose breaks into pyruvate molecule ?

Glycolysis is the process by which glucose is broken down within the cytoplasm of a cell to form pyruvate. Under aerobic conditions, pyruvate can diffuse into mitochondria, where it enters the citric acid cycle and generates reducing equivalents in the form of NADH and FADH2.

The function of each lichen part is as follows: the fungal partner (mycobiont) provides structure and protection, absorbs water and nutrients, and anchors the lichen to its substrate. The photosynthetic partner (photobiont) carries out photosynthesis, capturing sunlight and converting it into energy to produce food for both partners. Together, they form the lichen thallus, allowing lichens to survive in various environments.

Lichens are unique organisms that result from a symbiotic relationship between a fungus and an alga or a cyanobacterium. The lichen body consists of two main parts: the fungal partner, known as the mycobiont, and the photosynthetic partner, known as the photobiont.

The mycobiont provides structure and protection for the lichen. It absorbs water and nutrients from the environment, allowing the lichen to survive in various habitats. The mycobiont also plays a role in anchoring the lichen to its substrate.

The photobiont, on the other hand, carries out photosynthesis. It captures sunlight and converts it into energy, which is used to produce food for both partners. The photobiont is typically an alga or a cyanobacterium, and its photosynthetic activity is essential for the survival of the lichen.

Together, the mycobiont and the photobiont form the lichen thallus, which is the visible part of the lichen. The thallus can have various forms, such as crustose, foliose, or fruticose, depending on the arrangement and growth pattern of the fungal and photosynthetic components.

Lichens are remarkable organisms that can survive in extreme environments, including deserts and polar regions. Their ability to tolerate harsh conditions is due to the combined efforts of the mycobiont and the photobiont, which work together to ensure the lichen's survival.

The organism's colonies appear green with black centers on the agar, indicating a potential characteristic of pigment production in the organism.

The green color observed in the organism's colonies suggests the presence of a pigment produced by the organism. Pigments are substances that absorb certain wavelengths of light and reflect others, giving objects their characteristic colors. In this case, the organism likely produces a green pigment that imparts color to its colonies.

The presence of black centers within the green colonies suggests the accumulation or concentration of a different pigment or compound in the center region. This could be due to various factors such as differential growth, accumulation of metabolic by-products, or the production of a secondary pigment.

Identifying the specific organism based solely on the appearance of its colonies on agar is challenging without additional information. Further investigation, such as microscopic examination, biochemical tests, or genetic analysis, would be necessary to determine the exact species or characteristics of the organism responsible for the observed green colonies with black centers.

The rate of change of the volume of the balloon (sphere) is 150π cubic cm/min. The formula for the volume of a sphere is given by; V = (4/3)πr³.

Given that the circumference of a balloon (sphere) is increasing at a rate of 3π cm/min and the radius is 5 cm, we have to find the rate of change of the volume of the balloon. We know that the formula for the volume of a sphere is given by; V = (4/3)πr³. Differentiating with respect to time gives; dV/dt = 4πr² × dr/dt

We know that the circumference of a sphere is given by; C = 2πr

Differentiating with respect to time gives; dC/dt = 2π × dr/dt

Now we can find the value of dr/dt from the above expression; dr/dt = dC/dt ÷ 2πPutting the given value in the above expression, we have ;dr/dt = 3π ÷ 2πdr/dt = 3/2 cm/min

Now substituting the value of r and dr/dt in the expression for dV/dt; dV/dt = 4πr² × dr/dt dV/dt = 4π(5)² × (3/2) dV/dt = 150π

Therefore, the rate of change of the volume of the balloon (sphere) is 150π cubic cm/min.
