What is the powerhouse of the cell?

Mitochondria are semi-autonomous cells, which means that they only rely partly on the cell for division and growth. Mitochondria are contained in two membranes and have their own DNA and ribosomes. In addition, mitochondria are capable of providing their own protein. Mitochondria are also able to divide to produce more mitochondria. Many degenerative conditions and diseases are a result of defects within the mitochondria, which is commonly known as mitochondrial disease.

Which part of the cell contains chromosomes?

Although the shape and number of chromosomes varies among living organisms, all chromosomes are tightly wound around histones so they fit inside a cell. Complex organisms, such as plants and animals, have a linear arrangement of chromosomes, whereas bacteria usually have a circular arrangement of one or two chromosomes. The cells of complex organisms contain smaller, circular chromosomes. Similar to the makeup of bacteria, the chromosomes reside in the mitochondria outside the nucleus.

What is the boiling point of butanol?

The other kinds of butanol are called isobutanol, sec-butanol and tert-butanol. Isobutanol has a boiling point of 226 F. Sec-butanol has a boiling point of 211 F. Tert-butanol has a boiling point of 180 F.\nStandard butanol, also known as 1-butanol, is an alcohol molecule made up of an unbranched chain of atoms. The isomers are alcohol molecules with various branching structures. The different shapes give the different kinds of butanol different chemical properties, although they are still made up of the same number and kind of atoms. This is why the isomers have different boiling points.

What you need to survive on the moon?

Individuals planning to live on the moon can acquire breathable air by using heat and electricity to obtain oxygen from the moon’s soil. Evidence suggests that the moon’s south pole may have buried ice. People can mine the ice as a source of water for drinking and irrigation. It’s also possible to use water as rocket fuel by turning it into oxygen and hydrogen.\nHowever, people have to import liquid hydrogen from Earth if there isn’t enough water on the moon. The element can react with oxygen obtained from the moon’s soil to produce water. This is likely the least expensive method to..

What causes a ruptured blood vessel?

DermApproved states that telangiectasias can appear as red, blue or purple blood vessels. The appearance of broken blood vessels usually occurs on the face, especially the cheeks, nose and chin, the upper chest and the neck. This is especially noticeable in people with fair skin types. A common symptom of broken blood vessels is the observation of splotchy marks. To prevent blood vessel dilation and broken blood vessels, it is advised to use gentle cleansers that are fragrance and allergen free. Astringents should be avoided as well.\nMoisturizers that offer protection from UV radiation are re..

What are some facts about the element neon?

Neon has an atomic weight of 20.1797 atomic mass units and a density of 0.0008999 grams per cubic centimeter. Its name originates from the Greek term "neos," meaning "new." It makes up less than 1 percent of the atmosphere on Earth, despite being the fourth most prevalent element in the entire universe. As of 2016, scientists do not know of any compounds neon forms with other elements, although evidence indicates the possibility of it forming compounds with the element fluorine.\nMany of the bright, glowing signs seen outside of businesses get their glow from neon contained inside of light tub..

What is the formula to convert kilometers to miles?

Kilometers and miles are both units of length. Kilometers are the main unit of length in the International System of Units, or the metric system. Since being adopted in France in 1795, this system of units is utilized throughout most of the world. Miles are a unit of length in the customary system of units. This system is utilized in the United States and a few other countries.

What are some fun ways to teach kids about plant parts using diagrams?

For example, at GoBotany.NewEnglandWild.org, a website oriented toward teaching, students begin the plant identification process on the Simple Key page by assigning their plant specimen to one of six major categories based on descriptions and photos of plants and plant parts common to each category. After the student chooses a category, a list of subcategories displays with each, including a list of key characteristics of plants in the subcategory. Many of these characteristics are hyperlinks, and clicking on them brings up plant part diagrams. This website's Teaching page features inform..

Is NaOH a strong base?

Sodium hydroxide is also known as caustic soda or lye. It is a white solid soluble in water, methanol and ethanol. It also absorbs moisture and carbon dioxide in the air. When sodium hydroxide dissolves in water, it produces a large amount of heat, which is a reaction termed as an exothermic reaction. The resulting solution is odorless and colorless.\nSodium hydroxide also reacts with acids such as hydrochloric acid to form salts. For example, when sodium hydroxide reacts with hydrochloric acid, the reaction produces water and sodium chloride.\nSodium hydroxide has many industrial uses. It is ..

What does a balanced chemical equation allow one to determine?

For example, the chemical equation N2 + 3H2 --> 2NH3 is one mole of nitrogen molecules plus three moles of hydrogen molecules that create two moles of ammonia. The equation is balanced because the same number of moles of nitrogen and hydrogen are on both sides of the equation. There are two moles of nitrogen gas and six moles of hydrogen gas as reactants and products.\nA mole is a chemical ratio that describes the weight of a substance based on the size of its atoms and molecules. One mole of a substance is 6.022 x 10^23 molecules or atoms. One mole of ammonia weighs about 17 grams, whereas si..
