Information Science and Libraries

The smallest life form discovered until today 2010 is an Archaea microbe, roughly 200 nanometers across (the size of a large virus, which is not considered to be alive because of its inability to reproduce independently) found in an abandoned mine in Northern California in 2006 by Brett Baker working with Professor Jill Banfield.

Margin of error in science is where they are doing statics based on a sample known as a representative subset. Samples are picked based on the best information given. But since there is always a chance that not all information or details have been given in selecting the sample it makes it impossible to retrieve a 'true' representative subset. So margin of error in science is how well the scientist selected a sample that will allow them to predict what will happen with what they are studying.

To measure the mass of a container, place the empty container on a digital scale and record the reading. Then, add the items you want to measure inside the container and take the new reading. The difference between the two readings will give you the mass of the items in the container.

Metals have few valence electrons and tend to lose these electrons to form positive ions. This electron loss allows metals to achieve a stable electron configuration similar to the nearest noble gas, leading to the formation of positive ions.

Inertia is the tendency of an object to resist changes in its state of motion. When an object is moving and a stopping force like friction is applied, the inertia of the object causes it to continue moving until the stopping force overcomes its motion, eventually bringing the object to a stop. In this case, the greater the inertia of the object, the more force is needed to overcome its motion and bring it to a stop.

Solid expansion can lead to structural damage in buildings or infrastructure, causing cracks or distortion. It can also disrupt foundations, roads, and pipelines. Additionally, solid expansion can trigger landslides or rockfalls in mountainous regions, posing a threat to nearby communities.

Friction opposes the motion of objects, which can affect their inertia by slowing them down or preventing them from moving. Inertia is the tendency of objects to resist changes in their state of motion, so friction can either help overcome inertia by bringing an object to rest, or maintain its state of motion by providing a force in the opposite direction.

Expansion and contraction can cause rocks to crack or break apart. When rocks heat up, they expand, and when they cool down, they contract. Over time, this cycle of expansion and contraction can weaken the rock and lead to weathering and erosion.

Seasonal grasslands can be found in places where there are drastic changes in the weather from one season to the next. For example, it could be found in the tundra and parts of the northern steppes, where the grassland turns to an icy desert in winter. It can also be found in North-Central Africa south of the Sahara Desert, in a region called the Sahel, where a deserted landscape could turn into a grassland during the rainy season.

Solubility depends on the interaction between the solute and solvent molecules. Factors that influence solubility include temperature, pressure, polarity of the solute and solvent, and the presence of any common ions. Ultimately, solubility is determined by whether the forces holding the solute molecules together are weaker or stronger than the forces between the solute and solvent molecules.

Neptune was discovered by German astronomer Johann Galle and French mathematician Urbain Le Verrier in 1846. Le Verrier had calculated the planet's existence based on discrepancies in the orbit of Uranus, and Galle confirmed its existence by observing it through a telescope.

Scientists typically communicate the results of an experiment through scientific journals, presentations at conferences, or by publishing their findings in peer-reviewed research papers. This allows other scientists to review, replicate, and build upon the work.

It is a simple device. A variable electronic resister, called a thermistor, is used and is on the end of the cord. The resister varies it's resistance value depending on temperature. The probe must be placed in the area (outside) where you want the temperature. There is a second one in the unit itself and will show the inside temperature.

The name of the hardest solid is a diamond; it is the hardest object known to humankind.

A volcano is formed by pressure building up below the Earth's crust. Magma forces it way through weaknesses in the earth's crust. When the magma emerges it is called lava. When it cools, it solidifies into rock,or it may emerge though thin cracks,which are called fissure.Or it may be forced though wider pipes,that starts to build up, to a volcano.

Plants without green leaves, like the purple velvet vine, can make food through a process called heterotrophy. They obtain nutrients from other sources, such as decaying organic matter or by forming symbiotic relationships with fungi. These plants rely on alternative methods to obtain the energy needed for growth and survival.

Monochromatic refers to light composed of a single wavelength, creating a single color. Polychromatic, on the other hand, includes multiple wavelengths and therefore multiple colors. Monochromatic light appears uniform in color, while polychromatic light can be a mixture of colors.

The measurement of how much mass is contained in a given volume is called density. Density is calculated by dividing the mass of an object by its volume.

Things that can be observed with the senses are known as empirical evidence. This includes physical objects, sounds, tastes, smells, and textures that can be perceived through sight, hearing, taste, smell, and touch. Observing these tangible elements can provide concrete evidence for various phenomena.

Artificial flavors are not organic as they are synthetic compounds created in a laboratory, and not derived from natural sources. Organic flavors are made from organic ingredients that have been organically grown or processed.

Generally, liquids with lower viscosity and higher thermal conductivity tend to freeze more quickly. This means that liquids like water or milk, which have low viscosity and high thermal conductivity, will freeze faster than liquids like oil or honey.

A monochromatic source is a source of light of a discrete wavelength. White light is a mixture photons with wavlengths from 390 to 750 nm (what the human eye can detect). The monochrmatic light will have a specific wavelength. For example all photons have wavelength 200 nm.

A heterogeneous mixture has an uneven distribution of particles. In this type of mixture, the different substances are not uniformly mixed, making it easy to distinguish and separate the components. Examples include salad, cereal with milk, and a mixture of sand and gravel.
