Why are most people right-handed?

Although dyslexia and handedness are not related, researchers studying dyslexia found that a gene identified as PCSK6 also influenced handedness. Further research established that this gene does not work in isolation, but a network of genes contribute towards a propensity to left or right-handedness. These genes are also associated with the compartmentalization of the brain having to do with language ability. For most people, language ability is controlled by the left side of the brain and motor skills, such as handedness, are controlled by the right side. However, in left-handed people, this ..

What is the function of sensory nerves?

The nerve cells that make up the sensory nerves are commonly known as sensory neurons. These particular neurons are one of three different types of neurons that are found within the body. The other two neurons are known as relay neurons and motor neurons. Relay neurons carry messages from on segment of the central nervous system to another while motor neurons carry signals from the central nervous system to effectors, which is an organ that has a particular effect when it is stimulated. The message that is relayed throughout this process is commonly known as an impulse, and it is sent along ne..

What is DHMO?

Water consists of two hydrogen atoms (dihydrogen) and one oxygen atom (monoxide), thus the joke. Together, the words can sound scary to some, such as the "di-" in dihydrogen and the association of monoxide with "carbon monoxide."\nMany websites have written satirically about dihydrogen monoxide, thus creating the hoax. There is still debate over whether it is a formal or informal term, as scientists generally prefer to use hydrogen oxide as the chemical name for water without including the prefixes.

How do I describe the process of synapsis?

A synapsis occurs when the chromosomes form a pair of sister chromatids during the first phase of meiosis, which is referred to as prophase I. These sister chromatids connect to one another through RNA and protein combinations. During this process, they interlock and coil together. This is the crossover process. As this phase continues, the homologous chromosome pairs migrate toward either the left or right side of the cell. As this process moves to anaphase I, the synapsis ends. As it ends, the chromosome pairs separate. In later phases, these chromosomes are picked up by separate daughter ce..

What is the difference between 120v and 240v?

The standard rating for appliances in the United States is 120V, so most electrical outlets are 120V; however, some bigger appliances requiring more electrical power to operate use 220V or 240V. Most other countries on continents other than North America run on 220 or 240V power. This means that a voltage converter or step down transformer is needed to use a 120V rated appliance in a 240V outlet.

What is manganese nitrate?

It is soluble in water and a strong oxidizing agent, and it is used in industry to make other chemicals. It belongs to nitrate and nitrite inorganic compounds group, according to American Elements.\nManganese nitrate irritates eyes, mucous membrane and skin, and it is toxic when inhaled or ingested. When in vapor form, it can cause burns, death or severe injury.

What is the orbital notation for potassium?

Each shell is divided into subshells labeled s, p, d and f. The first shell contains two electrons, while the eight electrons in the second shell are distributed in two subshells: two electrons in the s-subshell and six in the p-subshell. The third shell has eight electrons distributed in a similar manner. The fourth shell has one electron in the s-subshell.\nThe single electron in the last shell is called the valence electron and gives potassium a valency of 1. Potassium readily gives away this single electron to form a positively charged potassium ion.

How many neutrons does carbon have?

Carbon-12, or carbon with six neutrons, is stable, and makes up about 99 percent of all carbon.The remaining 1 percent is mostly Carbon-13, the other stable isotope of carbon, which has seven neutrons. Carbon-14, with eight neutrons, occurs naturally in trace amounts and is often used to determine the age of very old objects, because carbon-14 decays at a slow, but consistent rate.

What are the ingredients used in making Tannerite?

Commercial Tannerite's oxidizer consists of 200-mesh ammonium nitrate and between 0 and 15 percent ammonium perchlorate, but the exact ratio is a trade secret. It is the rapid decomposition of this compound that gives Tannerite most of its explosive force.\nThe catalyst is made from three different compounds. The bulk of the catalyst, around 90 percent of it, consists of 600-mesh dark-flake aluminum powder. The remaining 10 percent is split evenly between 325-mesh titanium sponge and 200-mesh zirconium hydroxide.\nThe makers of Tannerite mix the oxidizer and the catalyst separately and bu..

What is Mars' distance from the Sun?

Mars, like the rest of the planets in the solar system, revolves around the sun in an elliptical orbit. When Mars reaches the point where it is closest to the sun in its orbit, the distance between them is 207 million kilometers. When it is at its farthest point, the distance between Mars and the sun is 249 million kilometers. One Mars year is equivalent to 687 Earth days or 669 Martian days.
