The serous membrane that covers the lungs is called Pleura.
It is a type of serous membrane that lines the thoracic cavity and encloses the lungs, creating a space called the pleural cavity, where a small amount of fluid is produced. It comprises two layers, the visceral pleura, which is adjacent to the lung surface, and the parietal pleura, which lines the chest wall, the diaphragm, and the mediastinum.
The visceral pleura covers the lungs, extending into their fissures, and is continuous with the parietal pleura. The parietal pleura is continuous with the mediastinal pleura, which surrounds the mediastinum and the diaphragmatic pleura, which lines the diaphragm.
The pleura serves to protect the lungs by reducing friction between the lungs and chest wall and by creating a sealed compartment around the lungs, which prevents the entry of air or fluid into the pleural space.
When the pleura becomes inflamed, it is called pleurisy, which is characterized by sharp chest pain that worsens with deep breathing or coughing. Pleurisy may be caused by a bacterial or viral infection, pulmonary embolism, heart failure, lung cancer, or other conditions. It is diagnosed by a physical examination, chest X-ray or CT scan, and treated by addressing the underlying cause, pain management, and sometimes draining the fluid from the pleural space.
Therefore, the correct answer is D. Pleura.

The partition that results from the inward growth of the cell envelope from opposite directions is known as the septum.
What is septum?The septum is a physical barrier that forms within a dividing cell to facilitate the separation of its two daughter cells. It happens in both eukaryotes and prokaryotes. The process of cytokinesis or cell division is responsible for the formation of a septum. When a cell has replicated its DNA and reached the end of the cell cycle, it begins the process of cell division.
The division of a cell into two daughter cells is known as cytokinesis. It is done in several different ways by different organisms. In prokaryotes, the division process is different from that of eukaryotes. When a cell is about to split in two, a septum forms, which is a dividing line that separates the two cells as they are formed.
The septum results from the inward growth of the cell envelope from opposite directions. It develops around the cell's center and then narrows as it grows in the middle. When the septum has grown to the appropriate size, it breaks through the cell's envelope, separating the two cells from one another. The cell division is completed when the septum has divided the cell into two parts, each with its own genetic information.

A group of individuals that can interbreed in nature and produce viable offspring would be considered to be a species according to the biological species concept. The biological species concept is a classification framework in which a species is a group of individuals that can interbreed in nature and produce viable offspring.
According to this concept, individuals from two separate populations that are unable to interbreed or that produce sterile offspring are considered to be separate species. Furthermore, the biological species concept stresses the need for reproductive isolation in the development of species. This approach assumes that for a species to be classified as separate from another, there should be no gene flow or hybridization among the two in the natural environment. The Biological Species Concept (BSC) is a way of defining what a species is.
According to the Biological Species Concept, a species is defined as a group of organisms that can interbreed and produce fertile offspring under natural conditions, but which are reproductively isolated from other groups. This concept was first proposed by Ernst Mayr, a German biologist, in 1942.

The enzyme pp is activated by decreased cAMP levels to promote glycogen synthesis via the activation of PKA. Glycogen is a large, branched polymer of glucose, which is stored in liver and muscle tissues.
The glucose in glycogen is released through a process called glycogenolysis when energy is required for use. Glycogen synthesis takes place via the enzyme pp, which is activated when cAMP levels are reduced. Protein kinase A (PKA) is then activated via the pp enzyme, which activates glycogen synthase (GS).In the body, glycogen synthase (GS) is an enzyme that catalyzes the polymerization of glucose into glycogen in response to insulin. Glycogenolysis is the breakdown of glycogen back into glucose. Glycogenolysis is also controlled by an enzyme called glycogen phosphorylase (GP). When glucose levels in the body are low, glycogen is broken down into glucose to provide energy to cells. When glucose levels are high, glycogen is synthesized and stored for later use. Glycogen synthesis is regulated by a complex interplay of hormones and enzymes in response to the body's energy needs.

C) Chlorophyll liberates an electron.
D) Protons are moved across a membrane.
E) Cells lyse in a hypotonic environment.
According to the chemiosmotic mechanism, ATP is generated when (D) protons are moved across a membrane.
It suggests that ATP synthesis is caused by a gradient of protons established across the inner mitochondrial membrane or the thylakoid membrane in photosynthetic organisms through the redox reactions of the electron transfer chains.
The transfer of electrons through the electron transport chain is coupled with proton translocation across the membrane in the chemiosmotic mechanism. This activity establishes an electrochemical gradient across the membrane with protons building up on one side of the membrane.
To achieve ATP synthesis, this gradient of protons must be restored to equilibrium by moving the protons back to the other side of the membrane. The energy derived from this gradient is then utilized for ATP synthesis.

c. allowing H+ ions across the mitochondrial membrane without passing through the ATP synthase.
d. blocking oxygen diffusion into cells
e. blocking the pumping of H+ ions to the inside of the mitochondria
Cyanide and carbon monoxide block ATP synthesis by inhibiting ATP synthase. Cyanide and carbon monoxide are toxic substances. Thus, the correct option is A.
What is ATP synthesis?ATP synthesis is the process of producing ATP using energy from different sources such as glucose or lipids. The process occurs in the mitochondria of the cell. Cyanide and carbon monoxide are toxic substances that can inhibit ATP synthesis in the cell. Inhibiting ATP synthase is the way that cyanide and carbon monoxide block ATP synthesis. ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate. It is also responsible for creating a proton gradient across the inner mitochondrial membrane.
When this gradient is established, protons are pumped into the intermembrane space. This results in the formation of a proton-motive force that drives the phosphorylation of ADP to ATP. The blockage of ATP synthesis occurs as a result of the disruption of the proton gradient. Cyanide and carbon monoxide bind to cytochrome oxidase, an enzyme that is responsible for the transfer of electrons to oxygen during the electron transport chain. This causes the electrons to be trapped in the mitochondrial respiratory chain, which leads to a reduction in the proton gradient. Thus, ATP synthesis is inhibited.
Therefore, the correct option is A.
