How does its magnetic field protect the Earth?

The Earth generates a magnetic field from the convection of molten metals, primarily iron and nickel, near its core. The twisting effect of these metals relative to the planet's spin generates a magnetic field that is usually strong and consistent. While the field is active, charged particles from the sun are deflected around the Earth along the field's lines of force. Some particles from the solar wind are carried along the field's lines to the north and south magnetic poles, where they are accelerated into the atmosphere and produce the aurora borealis and australialis. Withou..

What is the human life cycle?

Fertilization begins when a man's sperm cell enters a female's egg, creating a zygote. Inside the mother's uterus, cell division leads to the creation of a circulatory system, nervous system, heartbeat and organs. After the fetus grows and develops, it is ready for birth. The mother's body pushes the baby through the vagina, the birth process known as labor. When the baby is born, it is called an infant. Unlike many other mammals, the infant's brain continues to grow new neutrons until age 2. As children grow, they loose their baby teeth, which are replaced by their ad..

What are two organs found in the right upper quadrant of the body?

The body is divided into various regions for the purpose of description. The body has four abdominal quadrants and nine abdominal regions. Most of the organs and partial organs in the right upper quadrant function as part of the digestive system, but the right kidney deals with fluid regulation and excretion.

How do you convert 184 centimeters to feet?

Record your centimeter value to startFor your specific equation, you start by writing (or inputting into a calculator) the value of 184 centimeters.Divide your number of centimeters by the feet-conversion factorYou then divide 184 centimeters by the factor of 30.48.Take note of your final answerWhen you divide 184 centimeters by 30.48, you arrive at 6.04 feet, rounded. You may need to round depending upon how far out you are expected to report the decimal value in your answer.

What is an example of the word mitochondria used in a sentence?

Mitochondria are any cellular organelles that are located outside the nucleus of a cell. Mitochondria use cellular respiration to produce energy for these cells. They contain high levels of enzymes, fats and proteins.\n\nMitochondria have several other important cellular functions. These include generating heat, storing calcium used in cell signaling and regulating the growth of cells. \n\nThe word mitochondrion is New Latin and originates from the Greek words mitos, meaning thread, and chondrion, a diminutive word for grain. The first known use of mitochondria was in 1901.

What are some articles about cells?

"Latest in Heart Stem Cell Debate" is an article written by Kerry Grens on Oct. 26, 2015. In the article, the author reviews scientific studies on heart cells with the cKit marker that show the potential to regenerate cardiac tissue. "A Multitool for Cells" was published on Dec. 21, 2015 by Peter Ruegg. This article reviews the scientific discovery of a protein complex that scientists believe cells use to locate the source of a scent.

Is a gram bigger than an ounce?

In most cases, avoirdupois ounces are used. These are part of the system in common use in the United States. Troy ounces are used to measure precious metals and are not commonly used as a measurement outside of the commodities market. The United States is the only major market that still uses the ounce as an official unit of measure.

What occurs in a reaction between acetone and water?

When acetone is completely dissolved in water, any sample of the solution delivers equal parts acetone and water. Sometimes, dissolving acetone in water creates the appearance of bubbles. The bubbles are likely not an indication of the chemical reaction. Bubbles may be introduced through air that is trapped in the solution when acetone is poured into the water. Some solutions bubble because the chemical reaction between ingredients generates enough heat to boil; this is not the case with acetone and water.

How much is 100 centimes equal to?

In French-speaking countries, the centime is used to represent 1/100th of a unit of currency, just as 1 cent is 1/100th of a U.S. dollar. As for the value of a 100 centimes, compare the currency that the centime represents. If you are not in Europe, it may not be safe to assume that the centime is referring to 1/100th of a euro.

What is the yield strength of mild steel?

The yield strength of mild steel is 248 megapascal. Yield strength is the stress at which a material has undergone an arbitrarily selected amount of deformation, often 0.2 percent.This indicates that when the stress applied on mild steel is 248 megapascal, it shows a measurable amount of deformation, that is, 0.2 percent.The main purpose of yield strength is to describe and define the stress at which plastic deformation begins in a material, such as mild steel.
