What does Water do?
Why do we as humans need water? Why can’t we just go around all of our lives and do sports or activities without needing to drink water? What does water do for our bodies, and what happens if we drink too much/too little of it? We as humans need water because Water is essential to good health—and life. Up to 60 percent of an adult’s body weight and about 74 percent of a newborn’s body weight is water, making it the largest single substance in the human body. Water helps carry nutrients to the cells in your body, as well as carry waste products from the cells in your body. Athletes especially need water because water helps regulate body temperature by absorbing heat from your metabolism, as well as help lubricate the joints. Having water is a necessity, however there are complications if we drink too much and too little of it. Drinking too little water is dangerous because it can lead to dehydration. Dehydration can influence your mental functioning, your heart rate, and your ability to regulate body temperature and blood pressure. If you lose even 1 percent of your body weight in water, your physical performance is affected and you feel tired. If you lose 2 to 4 percent, your mental functioning is affected; a loss of more than 10 percent of your body weight is a medical emergency and if not reversed can lead to death. Sweating during exercise that is not compensated by drinking extra fluids; exercise even in cold weather can cause sweating. Hot, humid weather, High altitude, which causes rapid breathing and increased urine output, Illnesses such as poorly controlled diabetes, and illnesses that cause vomiting, diarrhea, or fever, Pregnancy, and Certain medications. Each of these conditions alone can contribute to dehydration; a combination of them can cause it more quickly. Although caffeine does cause you to urinate more frequently, the effect is short-term and does not typically cause dehydration. Both caffeinated and non-caffeinated...
...WhatDoes a Geneticist Do?
By Cindy Grigg
Directions: Fill in each blank with the word that best completes the reading comprehension.
Scientists who study genetics study genes and heredity: how certain characteristics are inherited by offspring because their parents had these characteristics. Do you have the same eye color as your mother or father? Do twins "run" in your family? These characteristics, or traits, are inherited. They are passed from your parents to you by genes. Genes (1) ____contain________ DNA that occupies a (2) _________specific_________ place on a chromosome. DNA (3) ___________Determines____________ a specific trait in the (4) ____________organism___________ . Even the fact that you were born a boy or a girl was determined by genes. DNA is found in the (5) __________nucleus_____________ of each cell. When a baby is made, one cell from the father joins with one cell from the mother. This tiny cell (6) __________contains_____________ all the information stored in DNA to make a new person - you! If you are a boy, you were given DNA from your father containing a "y" chromosome. If you are a girl, you were given DNA from your father...
WhatDoes Congress Do?
In order to best explain what Congress does, we can use the analytical lenses of constitutionalism, institutionalism and behavioralism. Before we can discuss what Congress does, it is important to understand the basic make up of our legislative body. We can view the basic makeup of Congress within the view of Constitutionalism.
The United States Constitution provides the structure of our legislative body. It gives us a bicameral legislature. This means that we have two chambers; the House of Representatives and the Senate. The Constitution contains rules that give the basic guidelines on how we elect our representatives, how long they will serve and the outline of how the legislative process works.
To arrive at Congress, one must be elected by his constituents. In order to be eligible to run for Congress, a candidate must be at least 25 years old for a House seat and 30 for a Senate seat. Candidates must be a U.S. citizen and must be a resident in the state in which they are running.
The size of Congress – 535 members – is set by the Constitution. There are 100 seats in the Senate and 435 seats in the House. Each state has two senators and at least one representative. The apportionment of the remainder of the seats in the House is based on the population as reported by the U.S. Census Bureau. Once elected to Congress, a member of the...
What is it and whatdoes it do?
What is a CVE? a list of information security vulnerabilities and exposures that aims to provide common names for publicly known cyber security issues. The goal of CVE is to make it easier to share data across separate vulnerability capabilities (tools, repositories, and services) with this "common enumeration."
An information security vulnerability is a mistake in software that can be directly used by a hacker to gain access to a system or network. See the Terminology page for a complete explanation of how this term is used on the CVE Web site
An information security exposure is a mistake in software that allows access to information or capabilities that can be used by a hacker as a stepping-stone into a system or network.
Isn’t CVE just another vulnerability database?
No. CVE is not a vulnerability database. CVE is designed to allow vulnerability databases and other capabilities to be linked together, and to facilitate the comparison of security tools and services. As such, CVE does not contain information such as risk, impact, fix information, or detailed technical information. CVE only contains the standard identifier number with status indicator, a brief description, and references to related vulnerability reports and advisories. (Note: The U.S. National Vulnerability Database (NVD) provides fix and other information for identifiers on the CVE List.)...
Don't wallow, shoot into the shower
A quick shower uses far less water than a long soak in the tub. Think twice before you have one!
Save your washing up for one wash
Instead of washing up as you go, save it up and do it in one go to minimise the amount of water you use. As one MoneySaver says, it's a great excuse to leave the washing up!
Conserve water and 'mulch' your garden plants
Mulching garden plants (covering with wood chippings or leaf mould) reduces the need for watering as they will retain moisture for longer. See the BBC's guide on how to mulch.
Love the shade - keep plants out of the sun
Moving pot plants and house plants out of the sun helps limit the amount of water they need once they've had their fair share of sunshine.
Watering the plants? Don't forget your roots
Use the simple trick of an upside-down water bottle with holes in it to get water direct to the roots of your plants - this should help save waste.
Turn it off - don't run the tap
When cleaning don't run the tap, instead use a wash bowl to rinse cloths.
Clean the car smartly
When you really get to the point you have to clean the car, use a bucket of hot soapy water and a watering can of clean water to rinse - no need to use a hose at all. Consider using waterless valeting products too.
Don't bathe pets, keep Fido dry
It can be bad for their...
Whatdoes a teacher do?
Before the start of the academic year the teacher is required to long-term plan, so there is an idea of what they plan to do throughout the year and that they are following the curriculum guidelines. The short term lesson plans are done on a weekly/daily basis. Plans are also put into place to accommodate any special needs. Classroom and outdoor activities are planned with the assistance of the teacher assist/volunteers.
At the start of the day it is up to the teacher/teaching assistant to ensure the classroom is ready for the children and all resources are available. A register needs to be taken at the start of each day, the teacher needs to ensure the children are attentive and are sitting on the carpet so they can hear their names being called. Any messing around and the teacher will deal with this in a calm manner. Time management skills are essential to ensure that they cover everything which has been planned for the day.
In addition to teaching the curriculum, teachers are required to assess children. In a classroom, the specific needs of students vary greatly - from developmentally delayed to talented and gifted. It is expected that the teacher will meet these individual needs. In order to assess the children the teacher may ask for assistance from the teaching assistant. Group and individual activities are planned to assess the children, reading, writing,...
What is Religion and whatdoes it do?
Whether religion is the basis for the noblest events in human history, or a negative force responsible for the worst atrocities in history it plays a significant role in human existence, it also provides order and structure goals for humanity. According to Oxford Dictionary religion could be defined as “a belief in superhuman controlling power in a personal God or gods entitled to obedience and worship”. Through scriptural quotations, human experience and evidence, people are able to witness how important religion is to human existence.
Because of religion, culture(s) is preserved; for example the Jewish culture. A religious person who indulgences in the religion of their choice can testify that decisions and crossroads they encounter are a reflection of their religion. So since these people are a participant in culture, their actions and reasoning contribute to culture. At one extreme we find people whose religious belief permeates their entire existence, who pattern their conduct closely on their religious beliefs, and who are quite literally prepared to die rather than betray them. Religion has little power to erase deeply-ingrained cultural traits. Thought experiment: suppose the Pope were to order all Irish Catholics to go to the authorities and reveal everything they knew about terrorist activities, under pain of mortal sin and excommunication....
...Drinking too much water can lead to hyponatremia, water intoxication, water poisoning and death
Liquid H2O is the sine qua non of life.
Making up about 66 percent of the human body, water runs through the blood, inhabits the cells, and lurks in the spaces between. At every moment water escapes the body through sweat, urination, defecation or exhaled breath, among other routes. Replacing these lost stores is essential but rehydration can be overdone. There is such a thing as a fatal water overdose.
The poison is the dose
Water can cause the brain to swell
share courtesy: http://news.bbc.co.uk
Drinking several litres over a relatively short period of time could be enough to cause water intoxication. Those most at risk include people taking ecstasy, as the drug increases thirst and facilitates the release of anti-diuretic hormones so more water is taken in but cannot be excreted. Also, elderly people because their kidney function may be impaired.
Strange but true; drinking too much water can kill.
In a hydration-obsessed culture, people can and do drink themselves to death.
As long as you are healthy and equipped with a thirst barometer unimpaired by old age or mind-altering drugs, follow Verbalis's advice, "drink to your thirst. It's the best indicator."
Beware of mindlessly drinking several...
...to produce more urine so the body weight can drop significantly so they fall into a certain category. Such sports like judo, horse racing, and weightlifting, when these drugs are taken give the athlete an unfair chance of beating their competitor(s). These also help an athlete to reduce the chances of detection of other drugs by diluting their urine. The main side effect of diuretics is dehydration but they can also cause headaches and dizziness and a loss in coordination or balance. This drug is also detected within the urine. Before, during and after exercise, it is essential that sportsmen and women take in a considerable amount of fluid, this is because dehydration can occur resulting in other side effects and also excessive loss of water effects the heart and kidneys, they could fail which mean this could be fatal to the athlete.
Narcotics help an athlete to push himself harder and further because his pain threshold is bigger, it helps him to continue exercising/ competing even when injury has occurred. Narcotics have similar effects to heroin or morphine. Narcotics are strong painkillers and they are usually competitors are tested for them when they compete. Many narcotics are illegal substances and not just in sport, these drugs are potentially addictive. Side effects from these drugs can seriously put an athletes performance in jeopardy because if the athlete continues to exercise, whilst injured it can cause further injury, even though...
