The Xenia tornado was an F5. It killed more than thirty people and a significant portion of Xenia. It was a very tragic event.

It began in Bellbrook, Ohio at 4:42 pm and moved northeasterly out of Warren county into southeastern Montgomery, and finally into central Greene county where it entered the Arrowhead subdivision and basically destroyed it. It continued through Xenia and the downtown area killing five people in the A&W Root Beer stand and headed for Central State University.

When it was over at least thirty-two people had been killed and subsequently two more firefighters died after attempting to fight a furniture store fire two days later. More than 1,600 were injured and thousands were left homeless. Weatherman Gil Whitney was one of the many heroes of that day who spotted the hook echo at WHIO-7 television station and went on the air to alert the viewers.

Jupiter is the largest planet in our solar system.

A young baby frog is a tadpole. A tadpole is adapted to live in water. For breathing, it has gills, which helps it remain inside water until it grows up to become a frog. Gill are breathing organs of fish also, and the mode of living of a tadpole is similar to that of a fish. When it becomes a frog, it is capable of breathing both in air and in water. For breathing in air, a frog develops lungs and for breathing inside water the skin is used.

One of the other names of the big dipper is Ursa Major.

There were a total of 17 Apollo missions, with Apollo 7 being the first manned mission and Apollo 17 being the final mission that landed on the Moon.

Countries near the equator, like the Philippines, typically have two seasons - wet and dry - due to their proximity to the sun. Areas farther from the equator experience four seasons because of the tilt of the Earth's axis, which causes variations in temperature and daylight throughout the year.

Magnetization of a needle is a physical change because it does not involve any chemical reactions. The alignment of the magnetic domains within the needle is rearranged to make it magnetic, but the composition of the needle remains the same.

Though the Moon always shows just one face to Earth, it revolves around the Earth in about 28 days. You would expect that 14 of those [Earth] days on the Moon would be Sunlit and 14 in darkness. [one fortnight for sunlight and the same for night]

So a Moon day takes about 14 times 24 Earth hours, and as many for a night on the Moon.

Mount Taal is approximately 1,020' (311 m) above sea level. Mount Taal is located in the Philippines and currently has 47 craters.

DNA is copied in a process called DNA replication. During DNA replication, the two strands of the DNA molecule separate. Then free DNA nucleotides pair with their complimentary nucleotides according to the base-pairing rule on each of the old strands of DNA. Once the process is complete, the result is two identical DNA molecules, each with one old strand of DNA and one new strand of DNA. Refer to the related link for an illustration.

The small-angle formula is θ = 2 * arctan(d / 2D), where θ is the angular diameter, d is the physical diameter, and D is the distance from the observer. When Mars is closest to Earth, its angular diameter is around 25 arcseconds. This is smaller compared to the maximum angular diameter of Jupiter, which can reach up to around 49 arcseconds due to its larger physical size.

A colloid is a heterogeneous mixture where the particles are intermediate in size between a solution and a suspension, making them visible only with the aid of a microscope. Due to the small size of the particles, they do not settle out upon standing, resulting in a stable mixture.

The antonym of study is neglect or ignore.

Chloroplasts are the organelles found only in plants that use sunlight to perform photosynthesis, which converts carbon dioxide and water into oxygen and glucose.

Typhoons can be predicted to some extent using advanced meteorological forecasting techniques. Meteorologists can track weather patterns and use computer models to predict the path and intensity of a typhoon. However, there are still uncertainties involved in predicting the exact trajectory and strength of a typhoon.

which photosystem (p680or P700) splits water? P680

A half moon appears when only half of the moon's illuminated side is visible from Earth. This occurs when the moon is at a 90-degree angle relative to the Earth and the sun, known as the first quarter or third quarter moon.

The speed of a spaceship can vary widely depending on its design and purpose. For example, the Voyager 1 spacecraft has reached speeds of over 38,000 miles per hour, while the New Horizons spacecraft reached speeds of over 36,000 miles per hour during its mission to Pluto. Some theoretical spacecraft designs, such as those using ion propulsion or antimatter engines, could potentially travel at much faster speeds.

Elements in the same group or column on the periodic table have similar properties. This is because they have the same number of valence electrons, which determines their chemical behavior. For example, all elements in Group 1 (such as lithium, sodium, potassium) share similar properties due to having one valence electron.

The cells in the retina and the cells that line your air-passages have only one thing in common: they are often seen in close proximity to each other in homework questions about what the relationship between retinal cells and air-passage cells might be.

it was made by Alfred Pandori in 1985 (Common Era [CE]) AD.

The subscript number after the preceding element in a compound tells how many atoms of that element are in a molecule or formula unit of the compound. For example, the molecular formula for water, H2O indicates that there are 2 atoms of hydrogen and 1 atom of oxygen in one molecule of water. The formula unit for the ionic compound calcium chloride, CaCl2, indicates that there are 1 calcium ion and 2 chloride ions in a formula unit of calcium chloride.

Fungi and bacteria break down organic matter in compost through a process called decomposition, releasing nutrients that plants can use. They thrive in the moist, oxygen-rich environment of compost piles, breaking down complex organic compounds into simpler forms. This breakdown process helps to transform the organic material into a nutrient-rich soil amendment.

Leather is a natural resource derived from animal hides. It is primarily used for making clothing, footwear, accessories, and furniture due to its durability and flexibility.

The title of the first modern scientist is often attributed to Galileo Galilei. Galileo was an Italian mathematician, astronomer, and physicist who made significant contributions to the fields of physics, astronomy, and the scientific method during the 16th and 17th centuries. His work laid the foundation for the scientific revolution.
