What is the morphology of Micrococcus luteus?

Micrococcus luteus is generally described as non-pathogenic, which means that it does not cause illnesses in people unless their immune systems are already compromised. Colonies of Micrococcus luteus typically grow on mammalian skin and are frequently found in or on the mouth and respiratory tracts of humans. These bacteria can also grow in soil and water as long as there is enough oxygen present.\nMicrococcus luteus is notable because of its fairly small genome size, especially when compared to other free-living bacteria. Its genome is only 2.5 million base pairs in size. Smaller genomes tend..

What do rhinoceroses eat?

Long grasses constitute as much as 40 percent of the black rhino's diet, but this species normally eats leaves, twigs and branches. White rhinos exclusively eat grass, which is why their heads appear lower to the ground as they walk. The main difference between the species is the shape of the animals' mouths.\n\nBlack rhinos have pointed upper lips, while white rhinos have square lips. The pointed lips are ideal for plucking leaves from branches.\n\nDigestion occurs towards the back of the rhinos' digestive tract. Bacteria ferment plant material in the stomach in the same way as..

What do you call an element or compound that enters into a chemical reaction?

A reactant is a reagent that is consumed during the reaction. For example, in the reaction NaCl + AgNO3 --> NaNO3 + AgCl, the reactants are NaCl and AgNO3. A solvent is used to help another chemical dissolve, but it is not itself consumed by the reaction. A catalyst is also not consumed by a reaction, but it instead is used to force a reaction between other elements or compounds to take place.

How many days can you survive without sleep?

Lab tests of rats in 1989 show near-death conditions or death came on in 11 to 32 days without sleep. Sleepio indicates that tests of sleep deprivation have failed to prove that lack of sleep directly caused death. Lack of sleep can contribute to lack of mental focus or deteriorating health, which may contribute to fatalities. Fatal familial insomnia is a rare, inherited medical condition considered terminal. One person was known to have died after six months without sleep, but the exact cause of death wasn't proven as sleep deprivation, according to Sleepio.

What are the environmental factors that affect kinetic energy and diffusion?

Diffusion occurs when molecules move randomly using thermal or kinetic energy. Molecules in a solution tend to achieve a state of equilibrium, becoming evenly distributed. In net diffusion, molecules move in a direction from higher to lower concentrations. If a membrane separates two areas of differing concentration of the substance, net diffusion occurs through the membrane.\nNet diffusion rates reflect the speed to reach equilibrium, not the speed of individual molecules. Temperature changes directly correlate to diffusion rates. Higher temperatures increase the kinetic energy of a substance..

How do you know when a volcano erupts?

Eruptive pulses are a one-time emission, lasting a few seconds to a few minutes. Eruptive phases are eruptions that continue for a few hours or days, switching between ash and lava expulsion. Eruptive episodes are several connected eruptive phases over the course of several days, months or years. In a single eruption, the style, strength and ejected material may change hour by hour.

What is filter paper used for?

There are different kinds of cellulose filter paper that each carry different qualitative and quantitative properties. Black band filter paper allows 100 mL of fluid to flow through it in about 20 to 30 seconds. It is designed for filtering thicker gelatinous solutions. White band filter paper allows 100 mL of fluid to flow through it in about 40 to 60 seconds. It is designed for filtering coarse crystalline solutions. Blue band filter paper allows 100 mL to flow through it in about 200 to 400 seconds. It is designed for filtering fine crystalline solutions.When selecting the proper filter pap..

How do sharks digest food?

Sharks frequently swallow things whole or in considerably large pieces. Because of this all of the breakdown must occur in the shark's U-shaped stomach. Some sharks, such as the Great White, have extensions in the esophagus that prevent food or prey from escaping before reaching the stomach. Enzymes and other acids in the stomach then work to form the ingested material into a thick, sludgy substance that is ready to be digested in the intestines. It is necessary for this soupy material to be as mushy as possible, because the valve leading from the shark's stomach to its intestines, t..

Does smell affect taste experiments?

In a taste experiment, the taste buds detect salty, sour, bitter or savory flavors, which then stimulate the sensory cells and transfer the taste information to the brain. The sensory neurons inside nasal passages detect the odors in the air, and this information is combined with data from taste buds to give the entire taste presentation. If something interferes with the ability to smell food, having an accurate taste perception is difficult.

What is an Exotic Angel plant?

A gardener that purchases an Exotic Angel plant is not only buying a well-known brand name, but is also purchasing a healthy plant. Although Exotic Angel plants come in a variety of species, the majority are easily recognized by the layman gardener and include ficus, asparagus, aloe and agave.\nAlthough each plant comes with specific care instructions and lighting requirements, Exotic Angel plants share many of the same care requirements. For instance, the plants need to be placed in a location that receives plenty of sun, as long as it is not direct light. They should be exposed to a humid en..
