What is a monocular microscope used for?

The invention of the microscope has lead to the discovery of otherwise imperceptible organisms, such as cells and bacteria. Compound microscopes utilize microscope slides, which are often made of silver or glass, where the specimen is mounted. Once the microscope's lenses are focused on the subject, the microscope produces a flat virtual image that requires some degree of analysis on the part of the observer.

Where do the enzymatic reactions of the Calvin cycle take place?

The Calvin cycle refers to the metabolic pathway found in plants, where carbon dioxide is processed to a carbohydrate. It plays a key role during photosynthesis. During this reaction, the cycle uses nicotinamide adenine dinucleotide phosphate, or NADPH2, for the electrons needed in making sugar, and adenosine triphosphate, or ATP, as a power source. The Calvin cycle is divided into three major stages: a carboxylation phase, reduction phase and regeneration phase.During the carboxylation phase, carbon diffuses into the stroma of the plants, and it is then fixed by the carboxylation of the compo..

What are some types of lime?

High-quality agricultural lime contains crushed limestone with a 37- to 40-percent calcium consistency. Heating limestone drives out carbon dioxide and creates burnt lime. Treating burnt lime with water creates hydrated lime, which is used primarily in construction. Magnesite, consisting of crushed magnesium carbonate rock, contains virtually no calcium. When treating acidic soil already sufficient in calcium, some farmers use burnt magnesite. It contains about 50 percent magnesium, around twice as much as high quality magnesite, says the NSW DPI.

What is a citrate test?

Using citrate leads to an increase in pH as alkaline byproducts accumulate in the microbe, according to the producers of VirtualUnknown Microbiology. Simmons citrate agar slant is used as the medium. It contains sodium citrate and mineral salts that supply carbon, and it contains ammonium phosphate as a nitrogen source. A pH indicator used for the test is brom thymol blue. When the pH is neutral, the color turns green, yellow means the pH is acidic and blue equals an alkaline pH.

Can we predict earthquakes?

In areas along large fault lines, where earthquakes occur more frequently, scientists can estimate the average length of time between major earthquakes. On the San Andreas fault, for example, there is usually a large-scale earthquake every 100 years. Many scientists subscribe to the theory that the next earthquake is likely to happen when the strain released by the previous earthquake is re-established.\nShort-term earthquake prediction is much more difficult to accomplish. There are some precursors to warn the community, but it is difficult to observe them and to determine if the precursors a..

What is Venus conjunct Pluto?

Venus conjunct Pluto is a type of aspect meaning. Aspect meanings have specific readings of personality traits that differ from each other.\nIf an individual has the aspect of Venus conjunct Pluto, they may display passion and deep emotions, while having a magnetic personality. The individual may cause others to feel emotions on a similar level as they do. They should take special care to avoid turning relationships into superfluous affairs that may reflect negatively on themselves and others.

What is the oil mixture for an Evinrude outboard motor?

Evinrude was founded by Ole Evinrude in Milwaukee, Wisconsin, in 1907. Evinrude filed for bankruptcy in 2000 and was bought by a Canadian company by the name of Bombardier Recreational Products. Evinrude produces two-stroke direct fuel-injected motors that vary between 25 and 300 horsepower. Carburetors were used in Evinrude engines until the late 1990s, when direct fuel-injection technology was made available.

What is the top of the foot called?

The top of the foot has a major tendon called the extensor hallucis longus. This tendon starts in the leg and extends all the way down past the ankle and ends at the big toe. This is the main cord that allows people to use their big toe and flex the ankle. The extensor digitorum longus also runs down the leg and through the foot. This is the tendon that allows all of the other toes on the foot to move freely.

How does a cactus make its own food?

Producing food in the arid desert region is not easy for cacti. They use a modified form of photosynthesis scientists call CAM photosynthesis. This process allows them to open the pores in their leaves to collect the carbon dioxide necessary for converting sunlight into glucose. They then close these pores and store the carbon dioxide internally until sunrise.\nCacti also have specialized root systems that allow them to gather moisture quickly from the limited amount of desert rain. The root system is broad but shallow. In some cacti, the first few drops of rain trigger the growth of fine root..

How is light transmitted through glass?

The electrons in glass are arranged on different levels and can change from level to level, but such a change requires energy. Photons carry energy from visible light as they encounter glass, but this energy is not enough to move the electrons in the glass to a higher level. As a result, the photons do not interact with the electrons in the glass at all and simply pass through. This process is known as transmission, and it gives glass its transparent appearance.\nOne of the reasons why visible light will pass through glass but not through other materials is because the molecules in glass requi..
