In the troposphere, CFCs are stable but in the stratosphere, CFCs are not stable and release damaging chlorine atoms when exposed to UV radiation.

Chlorofluorocarbons (CFCs) are compounds made up of carbon, chlorine, and fluorine atoms. They were once widely used in refrigerants, aerosol sprays, and foam insulation. However, because of their detrimental effects on the Earth's ozone layer, their use has been phased out.

In the stratosphere, CFCs are not stable and release damaging chlorine atoms when exposed to UV radiation. The chlorine atoms combine with ozone, resulting in a chain reaction that destroys the ozone layer, exposing the Earth's surface to harmful UV radiation.

Coal and natural gas are used to generate energy. However, their use can pollute the air, water, and soil by releasing gases and other materials. Options A (generation of electricity by burning coal) and B (generation of electricity by burning natural gas).

Coal is a fossil fuel that highly contributes to climatic change, polluting the air, water, and soil.

By burning it, its gases contribute to increasing the greenhouse effect and consequently producing global heat. This is affecting all forms of life that depend on these resources, including human beings.

During the coal combustion process, several particles are released into the air, polluting and being the cause of smog and acid rain.

Despite its reduced use in the last years, coal is still the principal fuel used by thermal, refineries, chemical, and still work industries.

Natural gas is a hydrocarbon composed of methane and other light hydrocarbons. As it is usually found in deep underground deposits, the origin of natural gas is associated with petroleum, and hence they share many similar energetic properties.

It is considered of better use since burning it implicates less environmental damage. When burning it to produce the same amount of energy, natural gas seems to emit fewer air pollutants, specifically CO₂, in comparison to oil or coal.

Options A and B are activities that cause pollution.

A. generation of electricity by burning coal

B. generation of electricity by burning natural gas

Answer: The digestive system is responsible for breaking down food and absorbing nutrients from it, while the respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide.

Explanation:

The digestive system consists of a number of organs that work together to process food and extract nutrients from it. These organs include the mouth, esophagus, stomach, small intestine, large intestine, and rectum. The digestive system starts with the mouth, where food is mechanically broken down by chewing and mixed with saliva, which contains enzymes that begin the process of breaking down food. The food is then swallowed and passes through the esophagus, which moves it to the stomach, where it is mixed with stomach acid and enzymes that continue the process of breaking down the food. The partially digested food is then moved to the small intestine, where it is further broken down and the nutrients are absorbed into the bloodstream. The remaining indigestible material is moved to the large intestine, where water is absorbed and the material is eliminated through the rectum.

The respiratory system consists of the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs. When we inhale, air passes through the nose or mouth, down the pharynx and larynx, and into the trachea. The trachea then splits into two bronchi, which lead to the left and right lungs. The lungs are made up of tiny air sacs called alveoli, where oxygen from the air we inhale is exchanged with carbon dioxide from the body's cells. The oxygen-rich blood is then carried back to the heart, where it is pumped to the rest of the body. When we exhale, the carbon dioxide is expelled from the body.

The given scenario describes a form of exploitation competition, where individuals of the same species are competing for a limited resource, in this case, the leaf.

Exploitation competition occurs when organisms indirectly compete with each other by reducing the availability of resources for other individuals. The caterpillars are consuming as much leaf as they can, leaving fewer resources for other individuals of the same species.
In contrast, interference competition occurs when individuals directly interfere with the ability of others to obtain resources, for example, when one organism actively prevents another from accessing a resource. Amensalism is a type of interaction where one organism is harmed while the other is neither helped nor harmed. Commensalism is an interaction where one organism benefits while the other is neither helped nor harmed. Finally, interspecific competition occurs between individuals of different species competing for the same resources.
Overall, the scenario describes an example of exploitation competition, where the caterpillars are indirectly competing with each other for the limited resource of the leaf.

Answer:

Spontaneous repair of peripheral nerves is made possible by Schwann cells, which surround the nerve fibers with an insulating layer, myelin. This fatty layer protects the nerves and increases the speed of transmission of nerve impulses.

Explanation:

Schwann cells are small elements that are created in order to form a layer around the axon of the nerves of the peripheral system. These cells surround the axon by an extensive layer of myelin that is discontinued by the presence of Ranvier's node. Myelin is a single cell organelle, a modified extension of the plasma membrane of the Schwann cell in the peripheral nerve. Its elaboration depends on the regulated expression of a set of genes in the myelinating glia, for which the Schwann cells require axonal contact, as well as to maintain the expression of these genes. Myelin acts as an electrical insulator that facilitates the conduction of the nerve impulse, it helps when the axons must regenerate, that is, when there is some injury or disease that prevents cell transmission. The goal is to help the nerve regenerate and grow again to reach the target tissues. Once the nerve is repaired, the cell regains its ability to produce myelin to cover the nerve with the insulating layer and allow the correct transmission of nerve impulses.

Energy requiring metabolic pathways that yield complex molecules from simpler precursors are: anabolic. The correct option is (B).

Anabolic pathways are those metabolic pathways in which simple molecules are combined to form more complex molecules. These pathways require energy, usually in the form of ATP, to drive the chemical reactions that synthesize complex molecules from simpler precursors.

Anabolic pathways play an important role in building the macromolecules needed for cellular structures and functions, such as proteins, nucleic acids, and complex carbohydrates. These pathways are also involved in the storage of energy in the form of glycogen, lipids, and other complex molecules.

Examples of anabolic pathways include protein synthesis, DNA replication, and glycogen synthesis. These pathways are often linked to catabolic pathways, which break down complex molecules into simpler ones and release energy.

Together, anabolic and catabolic pathways maintain the balance of chemical reactions in the cell, allowing it to grow, divide, and carry out its functions.

The Placenta is the structure through which a mother and an embryo exchange waste and nutrients.A placenta is a temporary organ that serves as the primary communication link between the developing embryo and the mother's body.

It has a large surface area that allows the exchange of gases, nutrients, and waste products between the mother's and the fetus' circulatory systems. Because of the existence of the placenta, the fetus's circulatory system does not have to be exposed to the mother's blood. The mother's and the fetus's blood do not mix directly. The placenta provides the growing fetus with all of its nutrient and oxygen requirements. The fetus sends carbon dioxide and other waste products back to the placenta, which removes them from the mother's body. The placenta is also responsible for the production of hormones that are necessary for the development of the baby's brain and other organs. It produces estrogen, progesterone, and human chorionic gonadotropin, among other hormones. The hormones are released into the mother's body and are transported to the developing fetus through the placenta.
