What happens when an ecosystem is destroyed?

Destroying the ecosystem causes rising of temperatures that may be too much for living organisms on the planet. It leads to deterioration of biodiversity that includes different types of animals and plants species. When habitats are destroyed, some species become extinct, hurting the food chain. Destruction of the ecosystem contributes to global warming that causes the rising of the sea level as a result of melting glaciers. Clearing of forests exposes the land to soil erosion that renders arable land unfit for production. Without nutrients and water in the soil, plants die. This situation dec..

Where is Meteor Crater in Arizona?

According to the official website, Meteor Crater is the world's best-preserved meteorite impact site, dating from a collision that occurred 50,000 years ago. The crater measures close to a mile across and is more than 550 feet deep. The visitors center houses an 80-seat theater and an air-conditioned indoor viewing area, with access to several miles of outdoor hiking trails.

What is Mercury's period of revolution?

Mercury is similar to the size of Earth's moon and is the smallest planet in the solar system. It is a rocky planet with a thin atmosphere of oxygen, sodium, hydrogen, helium and potassium. Mercury is the closest planet to the sun and can reach temperatures of 800 degrees Fahrenheit during the day. The sun appears three times bigger from the surface of Mercury than it does from the Earth. The surface gravity is also much weaker than the Earth, so a person weighing 100 pounds on Earth would only weigh 38 pounds on Mercury.

How do you derive Q=CV?

Capacitance is described as charge storage, which is also C=Q/V, and is illustrated by parallel plate arrangement. From the equation C=Q/V, the units are in coulomb/volt, which is equal to the Farad. Q is the magnitude of charge stored on each plate. V is the voltage applied to the plates. Two parallel plates are the most common capacitor. When the plates are largest and closest together, the greatest capacitance occurs. Capacitance can be increased by inserting a dielectric material between the two plates.

How does lightning form?

According to the PBS website, lightning contains a large amount of energy and heats up the surrounding air up to 54,000 degrees Fahrenheit. Since light travels at a rate of 186,000 miles per second, far faster than sound, people see lightning before they hear thunder.\nNASA's SciJinks website notes that lightning often happens between or within clouds. Lightning can be seen from space. NASA's GOES-R Geostationary Lightning Mapper is designed to follow and study lightning that occurs all over the Western Hemisphere.\nLightning can also be dangerous, adds National Geographic. Every per..

What parts of the body does otorhinolaryngology treat?

Otorhinolaryngology, also known as ENT, is the oldest medical specialty in the United States, according to MedicineNet. Specialists in this field practice as general ENT specialists or further specialize in pediatric ENT, facial and reconstructive surgery, head and neck surgery, laryngology, or rhinology.\nIssues treated by otorhinolaryngologists range from common ear infections, sinusitis and tonsillitis to more serious conditions, such as head and neck tumors, notes Advanced ENT and Allergy.

Why did DNA technology lead to more use of cladistics?

Cladistics places organisms in clades – family trees composed of the species in line with its ancestors and descendants. Branches off the direct line become new clades. A cladogram captures this information in a graphical representation of lineages and branching.\nThe speed at which DNA sequencing identifies organisms is overwhelming traditional species-based taxonomy approaches. Cladistics positions organisms on a genomic map but does not account for the evidence of species of new organisms nor for the recording of their genomic profile. Genetic coding provides a method to capture genetic i..

What are some famous Hubble Space Telescope images?

The 1999 image of planetary nebula IC 418 gave scientists a glimpse of the complexity of the nebula, contrary to the round and featureless images of the former star scientists had before. Many scientists considered nebulae to be simple, but images like this one showed microstructures and irregular shapes among nebulae. As of 2015, scientists are still trying to figure out what created this nebula's structure.\nThe 2004 to 2006 images of the dust belt near the star Fomalhaut revealed an unexpected shape for the belt, and led to inquiries into its structure and creation. Photos of Uranus an..

What are anatomy and physiology?

Students in anatomy will learn about the structure of and relationship between the parts of the body. There are different subsets of anatomy, including:Gross anatomy, which is the study of body parts that are visible to the naked eye. Some examples are the heart and lungs.Histology is the study of tissues at the microscopic level.Cytology studies cells at the microscopic level.Physiology students study the functions of the body as a whole as well as the functions of the different body parts. Neurophysiology is the division that studies how the nervous system functions. In a college or universi..

How long does it take blood to congeal?

There are 13 different clotting factors involved in blood coagulation, according to the National Hemophilia Foundation. If there is a deficiency in production, or if the body produces a defective form, then an individual may develop a bleeding disorder. Depending on how extreme the condition is, the disorder can cause mild symptoms such as nosebleeds to severe symptoms such as internal bleeding. Medications, such as aspirin, heparin and warfarin, in the bloodstream also impact coagulation.
