the production of alcohol by yeast cells is the result of

Answers

Answer:

Fermentation

Explanation:

Hope this helps!

The production of alcohol by yeast cells is the result of anaerobic respiration. The correct option is D).

What are anaerobic respirations?

All living cells undergo respiration, a chemical activity that releases energy from glucose. Without oxygen, anaerobic respiration occurs and produces less energy but does it more quickly. Fermentation refers to anaerobic respiration in microorganisms.

When you work out vigorously, your muscles engage in anaerobic respiration. Compared to aerobic respiration, less energy is released because glucose is not completely broken down.

During intense activity, lactic acid accumulates in the muscles. Later, the lactic acid must be oxidized to produce carbon dioxide and water.

Therefore, the correct option is D) Anaerobic respiration.

Plants using the CAM pathway occur in many locations but are most common in very arid locations, such as deserts. What deserts occur in North America and where are these deserts located?

Answers

The desert that occurs in North America is the Great Basin Desert and it is located at Nevada of North America.

CAM pathway, which is also called Crassulacean Acid Metabolism, is a pathway that involves carbon fixation that occurs in plants growing in arid areas.

With this pathway these plants are able to photosynthesize during the day, but only exchange gases at night.

An arid habitat is an environment that is characterized by extreme lack of water, example is the desert.

what would happen to the carrying capacity of the ecosystem & why

Q-a volcano covers an area with 2 feet of lava

Answers

Answer:

The carrying capacity would shoot downward.

Explanation:

The area would no-longer be able to support organisms or the ground until the lava cools off. Even after then, any plants that may have been there will be gone, meaning that the ecosystem can now support less herbivores, as well as less primary producers (plants).

Less plants, means less herbivores, which means less of the animals that eat the herbivores (secondary and tertiary consumers).

Answers

Answer:

I believe it would be B.) Quick drop in dissolved oxygen

Quick drop in dissolved oxygen is a possible consequence of solid pollutants in a lake or river.

What is Biological Oxygen Demand?

Biochemical oxygen demand (BOD) is the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic conditions.

Solid pollutants in freshwater bodies like river and lake generally corresponds to organic wastes such as leaves, flowers and clothes which lead to increase in number of microorganisms in these water  that further results in increase of BOD.

Drastic increase in microorganisms lead to drop in amount of dissolved oxygen in water, thus the possible consequence of solid pollutants in a lake or river is quick drop in dissolved oxygen.

what is the cell wall function and factory part or worker?

Answers

Answer:

Major cell parts function just like the structures and people who work together in a factory. Cells have strong cell walls and a cytoskeleton to keep their shape; the walls are made of fiber for protection just like a factory building has sturdy walls for support.

The cell wall serves as a protective and structural layer surrounding plant, fungal, and bacterial cells. It provides rigidity, support, and defense against external pressures and pathogens.

In various species, the cell wall serves as a robust outer layer. Its primary component in plants is cellulose, which helps to preserve cell structure, limit excessive water absorption, and promote growth. Chitin is found in the cell wall of fungi, providing both structural integrity and protection.

Bacteria have a variety of cell wall compositions; peptidoglycan, for example, is an essential part of many bacterial cell walls. Along with other cellular components, this "factory-like" part of the cell performs its functions. It is comparable to a factory's base, supporting the cell's framework, and worker, guarding against threats and preserving the cell's overall operation.

Explanation:

Photosynthesis is a chemical reaction that takes place to convert light energy. The photosynthetic light-dependent reaction forms glucose, ATP, and NADP⁺. Thus, option A is correct.

What is a light-dependent reaction?

A light-dependent reaction is a photosynthetic reaction that occurs in the presence of sunlight and produces chemical energy in the form of NADPH and ATP.

The products of the photosynthetic light-dependent reaction are used in light-independent reactions. In light-dependent, the photosystem gets excited and produces ATP from ETC, leading to reduction of NADP⁺ and photolysis of the water molecule.

Therefore, ADP and NADP+ are produced at the intermediary stage of the light-dependent reaction which makes them different from the light-independent reaction.

The Vedas is:A. writings from the Mauryan EmpireB. the polytheistic religion of IndiaC. wisdom literature and philosophy in SanskritD. religious prayers and ritual of China (Suited for Spacewalks - Adapted from NASA) Following Gemini, the Apollo program added a new dimension in spacesuit design because actual spacewalks, on the surface of the Moon, were now to occur for the first time. As with Mercury and Gemini space garments, Apollo suits had to serve as a backup pressure system to the space capsule. Besides allowing flexibility in the shoulder and arm areas, they also had to permit movements of the legs and waist. Astronauts needed to be able to bend and stoop to pick up samples on the Moon. Suits had to function both in microgravity and in the one-sixth gravity of the Moon's surface. Furthermore, when walking on the Moon, Apollo astronauts needed the flexibility to roam freely without dragging a cumbersome combination oxygen line and tether. A self-contained portable life-support system was needed. The Apollo spacesuit began with a garment that used water as a coolant. The garment, similar to long johns but laced with a network of thin walled plastic tubing, circulated cooling water around the astronaut to prevent overheating. A multi-layered pressure garment was worn on top of the cooling suit. The innermost layer of this garment was a comfort layer of lightweight nylon with fabric ventilation ducts. On top of this was a layer of neoprene-coated nylon surrounded by a nylon restraint layer. This layer contained the pressure inside the suit. Improved mobility was achieved by bellow-like joints of formed rubber with built-in restraint cables at the waist, elbows, shoulders, wrist, knees, and ankles. On top of the pressure layer were five layers of aluminized Mylar for heat protection, mixed with four spacing layers of non-woven Dacron. Above these were two layers of material for additional thermal protection and a non-flammable layer of Teflon coated in a fibrous cloth. The outermost layer of the suit was white Teflon cloth. The last two layers were flame resistant. In total, the suit layers provided pressure, served as a protection against heat and cold, and protected the wearer against micrometeoroid impacts and the wear and tear of walking on the Moon. Capping off the suit was a communications headset and a clear plastic pressure helmet. Slipped over the top of the helmet was an assembly consisting of sun-filtering visors and adjustable blinders for sunlight protection. The final items of the Apollo spacesuit were lunar protective boots, a portable life-support system, and custom-sized gloves with molded silicone-rubber fingertips that provided some degree of fingertip sensitivity in handling equipment. The life-support system, a backpack unit, provided oxygen for breathing and pressurization, water for cooling, and radio communications for lunar surface excursions lasting up to eight hours. Furthermore, back inside the lunar lander the life-support system could be recharged with more oxygen and battery power for additional Moonwalks. During the Apollo program, 12 astronauts spent a total of 161 hours of extravehicular activities on the Moon's surface. Additional extravehicular activities were spent in microgravity while the astronauts were in transit from the Moon to Earth. During a total of four hours, one astronaut, the command module pilot, left the capsule to retrieve photographic film. There was no need for the portable life-support system away from the Moon, as those astronauts were connected to the spacecraft by umbilical tether lines supplying them with oxygen.Drag each label to the correct location on the image.
